BMW Drivetrain Parts for BMW E36 (1992-1998) M3

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Even after rebuilding your manual transmission shifter with brand new BMW components or installing a short shift kit, your shifts will still be at the mercy of soft factory bushings. Designed with 100% comfort and low manufacturing costs in mind, BMW's factory carrier bushing offers a freedom of movement on all axis, resulting in "factory installed slop".

The ZF S5D 320Z 5-speed transmission is known for its robust design, exceptional durability, and impressive power-handling capability. Unfortunately, as these transmissions age, shifter-related issues have become increasingly common. Problems such as difficulty selecting gears, a sticky shifter, or a decline in shift quality are often the result of worn detent springs, pins, and bushings. These components are essential for precise gear engagement and proper shifter centering, making their replacement a critical step in maintaining optimal performance.

Replacing detents requires specialized tools known as "drifts," which are notoriously hard to find. Fortunately, we've developed a complete Detent Tool Kit, featuring five precision-engineered drifts designed for exact fitment in the ZF transmission's detent bores. This toolset makes detent replacement straightforward and minimizes the risk of damage to internal transmission components.

Features

Complete Tool Kit: Includes five precision-machined drifts specifically designed for the ZF 5-speed transmission’s detent bores and caps. Hassle-Free Detent Replacement: Simplifies the process of removing and installing detents with professional-grade precision. Protects Your Investment: Reduces the risk of damaging internal transmission components during service. Durable Construction: Made from heavy-duty 1045 steel for exceptional strength and long-lasting reliability.

Give your factory clutch a heavier motorsport feel or make your extremely tough clutch more drivable! If you have an E36 there is absolutely no reason you don't have this clutch pedal! Your factory E36 clutch pedal is made of flimsy plastic with no adjustment at all, leaving you to the mercy of the clutch you have.

Our Turner Performance Adjustable Clutch Pedal is a rigid design that gives you the ability to fully adjust your clutch feel and performance. With both upper and lower adjustments this is the best pedal on the market to fine tune your clutch pedal just the way you like it. The upper eccentric provides an adjustable pedal ratio to fine tune clutch pedal effort(how heavy the pedal feels). The lower adjustment is to change the position of the clutch assist spring, this allows you to choose where the clutch assisting spring engages. Changing where the spring engages will move the area of tension on your clutch from lower, middle to higher for maximum adjustment.

Your race car no longer needs to have a clutch that makes the car undriveable on the street. Your track car can now be your daily driver or weekend cruiser.

Features:

Adjustable throw
Capable of quicker shifts
Three lower mounting points for the spring to adjust where the assistance engages
Eccentric mount for master cylinder to adjust leverage ratio and pedal feel(weight/force needed to engage the clutch)
Self lubricating bronze bushings
All necessary hardware required for installation
Pedal body and pedal are constructed from 6061-T6 aluminum and type II black anodized for a great finish
NOTE: This Clutch Pedal does not include the Compression spring and the original spring must be reused. If you'd like to purchase a new spring, please see:

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

FEATURES & BENEFITS

Simplifies bleeding the BMW clutch hydraulic system by reducing trapped air in the slave cylinder Eliminates excessive pedal pumping and inconsistent clutch feel Helps achieve firm, consistent clutch pedal engagement Crafted from high-quality aluminum for strength and longevity Durable black anodized finish resists wear and corrosion Designed for both DIY enthusiasts and professional technicians PRODUCT DEVELOPMENT

Our Clutch Slave Cylinder Bleeder Tool was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

Sometimes choosing the correct shift kit proves difficult when you dual-purpose your favorite vehicle, we understand this well. The early days for any race enthusiast usually begins with a car that is needed to daily drive and setup to get out on the track. What becomes difficult is properly modifying that car to feel comfortable in both situations which is why we took this view on our new short shift line. This upgraded lever is a quick swap option to replace the standard shift lever that come with our kits so you can keep your hands closer to the wheel while shifting at high speeds. Designed from anodized aluminum this lever looks great in any interior for the daily driver who simply prefers the taller lever look and feel.

NOTE THAT THESE ARE DESIGNED TO WORK WITH TURNER MOTORSPORT SHORT SHIFTERS ONLY - We wanted to give you the option to buy one separately, in case you changed your mind after buying our short shifter.

Features:

Compatible with stock shift boot fits nicely into the machined groove at the bottom of the lever to maintain a clean look in the interior.
Machined from 6061-T6 aluminum and type II anodized for exceptional durability and corrosion resistance.
Available in either black or clear anodize to match your vehicle’s interior.
Rally shift knob is machined from black delrin.
Unlike aluminum, delrin will not hold heat so on those hot days you won’t have to worry about burning your hand on a knob that’s been baking in the sun.
Shift knob is threaded onto the end of the shift lever utilizing a standard ⅜-16 thread to allow for easy removal and attachment of your favorite beer tap or other accessory.
“Quick Change” height adjustable upper shift lever design allows for quick swapping between optional “OE” style and “Rally Style” upper shift levers.
22mm adjustment range to fine tune shifter throw and feel.

The ULTIMATE shifter upgrade for your BMW! Experience more precise throws, less shift lever travel, and an all-around transformation in your shifting experience.

For dozens of years, enthusiasts have critiqued the imprecise and vague feeling of BMW manual transmissions. Plagued with long throws, fore and aft play in gear, and a generally loose feeling, your OEM BMW shifter leaves much to be desired. While most standard carrier-mount short throw shifter kits will aid in reducing throw length and eliminating side-to-side play in gear, some enthusiasts long for a hardcore, race-inspired shifter that completely removes play and excessive throw length. At Turner Motorsport we share the same desire and set out to offer the ULTIMATE upgrade with this Performance Chassis Mount Short Shifter.

WHY UPGRADE?

Factory BMW shifter assemblies are complex by nature. The main component of this assembly is the shift carrier, a cast aluminum piece positioned inside the transmission tunnel that incorporates bushings at both ends for mounting. Like most factory parts, these bushings are designed to reduce NVH (noise, vibration, and harshness) transmission to the cabin. To the spirited driver, however, these bushings translate to flex and vagueness in the shift lever. Moreover, because this carrier is mounted to both the transmission and the body, the entire shifter assembly will "float" with the driveline, further increasing the vague and imprecise feeling of your shifter.

Our Performance Chassis Mount Short Shifter removes the shift carrier assembly entirely—removing any prospect of flex caused by bushings or driveline movement. By contrast, this chassis mount shifter offers a drastic reduction in shift lever travel, vagueness, and side-to-side play. An elevated base allows for moving the fulcrum point upwards, resulting in a much shorter and more precise throw. Shift times are further reduced by a tall, "rally style" shift lever, used to aid in leverage while also bringing the lever closer to the steering wheel. Our design incorporates a proprietary centering spring design, which is adjustable for increasing or decreasing self-centering force. In short, this design eliminates all the drawbacks of your factory BMW shifter, translating to more control, greater precision, shorter throws, and faster shift times.

FEATURES & BENEFITS

Reduced Throw: Modified shifter geometry and heightened fulcrum point translate to a shorter shift lever throw
Improved Shifter Feel: Eliminating the shift carrier and associated bushings drastically reduces "slop" and side-to-side play in the shift lever
Increased Precision: Mounting the shifter to the chassis allows for little to no variation in gear selection
Universal Fitment: Fits many BMW chassis with the provided base plate and hardware (see "Fits These Cars" for exact fitment information)
DESIGN

6061 aluminum, 4130 steel, and 316 stainless steel construction
A type-II black anodized finish
Adjustable self-centering spring
"Rally Style" shift lever
Spherical bearing pivot with maintenance-free brass insert
Product Development:

Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer and rigorous long term product testing.

If allowed in the rules these solid aluminum transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

Product features and benefits:

  • Crisper throttle response, positive shifter location, direct power transfer
  • Precision machined billet 6061-T6 aluminum housing
  • Grade 10.9 stud - fear not, big turbo owners
  • Engineered in-house and made in America

We have always loved BMWs, but one of their shortcomings has always been shifter throw and feel. Even driving your BMW home from the dealership, you might realize that the shifter throw leaves something to be desired when you find your right hand in your backseat when shifting into fourth gear. Things only go downhill from here, as these cars increase in age and mileage shifts feel less and less precise. Here at Turner, we CAD design everything in house and source the best materials to give you a truly amazing product and enhance the driving experience in your ultimate driving machine. After extensive testing and development, we are proud to present you with our Turner Motorsport short shifter. We wanted to develop something that could fit any BMW owner’s preferences - our engineering team decided this could be designed a height and throw adjustable short shifter that also features a “Quick Change” rally lever extension that allows you to easily swap back and forth between OE height shifter and the longer, rally lever you see in the product photos. Why the rally lever extension? Having the added height allows you to keep both hands closer to the wheel through shifts - this is especially helpful on the track, but we like it in our daily drivers too.

The 6-speed Getrag 420G transmission, found in the European E36 M3 Evolution and E46 M3, has become an increasingly popular swap amongst E36 owners. Its increased strength, longevity, and overdrive sixth gear make it a great choice for both track cars and daily drivers. Unfortunately, many of the components needed to complete this transplant have become hard to source. Despite increased demand from enthusiasts, BMW has blocked the sale of European E36 M3 parts into North America.

With this in mind, our team of engineers went to work designing a direct replacement and upgrade for the unavailable, 420G-specific shifter arm. Precision-machined from 6061-T6 billet aluminum and clear anodized, our replacement carrier is durable, lightweight, and built to last. It is dimensionally identical to the OEM carrier, ensuring compatibility with the OEM shift carrier bushing, shift lever, and our Double-Adjustable Short Throw Shifter Kit (T#557266).

Features & Benefits:

6061-T6 billet aluminum construction provides excellent durability and longevity Mil-spec clear anodized for superior corrosion resistance Dimensionally identical to its OEM counterpart, ensuring compatibility with all factory shifter components Confirmed compatibility with the Turner Motorsport Double-Adjustable Short-Throw Shifter Kit (T#557266) Product Development:

Its increased strength, longevity, and overdrive sixth gear make it a great choice for both track cars and daily drivers. Unfortunately, many of the components needed to complete this transplant have become hard to source. Despite increased demand from enthusiasts, BMW has blocked the sale of European E36 M3 parts into North America.

Recognizing this issue, we set out to develop a replacement for the unavailable, 420G-specific selector rod. Like all OEM selector rods, the factory part uses single-shear attachment, allowing for deflection within the shifter linkage. The result? Vague, imprecise gear selections that detract from your overall driving experience. The dual-shear selector rod (DSSR) design spreads the torsional force of gear selections across the selector rod joint, reducing deflection for increased precision. Our dual-shear selector rod is precision-machined from durable 304 stainless steel to further reduce deflection and resist corrosion.

Features & Benefits:

Provides a more positive feel in the shifter by reducing play in the linkage due to minimized deflection Manufactured from 304 stainless steel for superior corrosion resistance and durability Replacement for 25112228055 (European E36 M3 Evolution) Works with the OEM shift lever and OE-style short-throw shifter kits Kit Includes:

Single piece 6061 construction, optimized cooling, provisions for temp sensor, and external cooler with removable air duct.

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing our diff cover can handle anything you throw at it. Not only is it an absolute masterpiece to look at but the billet diff cover checks all the boxes for features needed. Reinforced mounting ears for strength and stability, never again will you break an ear off your diff cover like the factory units are known to do. Each ear is not only unified with the one-piece billet cover but also feature added material for the highest durability possible. This diff cover is cool, literally, the entire construction was designed with optimized cooling in mind. External fins are strategically placed on the rear face, bottom, and between the mounting ears of the cover, serving as effective heat sinks for optimal heat dissipation. This ensures stable temperatures, promoting longevity for both the fluid and your differential. Additionally, the internal design ensures continuous oiling and lubrication to the ring gear, maintaining its stability and preventing fatigue by controlling heat more effectively. An internal baffle at the cover's corner helps maintain proper pressure and prevents cavitation.

All of the OEM features were retained along with the upgrades. The mounting surface was designed to be compatible with both the OEM gasket or RTV of your choosing, some people don't trust the gaskets and we get it. You can transfer your speed sensor directly to your upgraded billet cover and it even features a provision for the sensor wire mounting. Factory bushing geometry allows you to use any E36 diff busing including rubber, poly, and even solid mounts. The drain and fill plugs on the diff cover are upgraded to -6AN using the provided high-pressure fittings with replaceable o-rings. The drain and fill plugs can now also be used for expanding to an external oil cooler allowing you to further expand the fluid capacity for optimized cooling and service intervals. To keep an eye on things from the driver seat is 1/8 NPT provision for temp sensors, this product from Turner has you covered at every turn.

Why the upgrade?

If you're new to differential covers used in earlier generations like the E30, you'll find significant improvements in the OEM E36 cover. Unlike the E30's single mount design, the E36 features a dual mount design, which was introduced to address common issues such as broken mounts due to worn-out bushings and aggressive driving. This upgrade significantly enhanced durability and reliability.

While the factory E36 differential cover was a significant improvement with its dual mounts compared to the previous generation, there are still some shortcomings that the original cover doesn't address. Most factory differential covers, including those on the E36, are cast from aluminum. However, due to the porous nature of cast aluminum, the mounting ears on these covers cannot withstand the intense shocks typical in motorsport or in vehicles with significantly increased power.

Upgrading to our Reinforced Billet Differential cover gives you the strength you need to push your car to its limits without worrying about snapping a diff mount from clutch kicking or other shocks to the drivetrain. In addition to its enhanced strength, this differential cover includes numerous other upgrades and conveniences. These include improved cooling and lubrication for the ring gear, upgraded fill and drain plugs, and the option to expand an external oil cooler for extreme motorsport usage. Designed to complement both upgraded daily drivers and extensively modified track cars, it also boasts a visually appealing design.

Key Benefits:

Reinforced mounting ears for strength and stability - never again will you break an ear off during an aggressive drive or track event
External fins on the back side, bottom, and mounting ears on the casing for maximum cooling and consistent fluid temps

Made in the USA If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. We originally developed these mounts for E36 and E46 World Challenge racing but they also work perfect in BMW Modified and SCCA club racing and SpecE46 (SE46). These are machined from solid aluminum and have zero deflection. The engine torque will cause a rubber or urethane mount to flex or deflect. The stiffer the material the less movement there is and the more torque is passed through the driveline (instead of being wasted winding up the mount). At the transmission end the flex-free solid mounts will give smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We have designed these mounts so the engine is 5mm lower and the transmission is 1mm lower than the factory mounts. This helps lower the center of gravity for better balance and handling. We very strongly recommend using the transmission and engine mounts together as a complete kit. Mixing a rubber mount with a metal mount will cause undue stress on the mouting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used. This kit fits the E36, E46, Z3, and Z4 6 cylinder models listed below, including M3 models.

These are a no-compromise design for all-out racing use. Full solid aluminum mounts should not be used on street-driven cars. Because there is no material to absorb vibration these will be quite harsh for regular street use (track cars don't care about noise).

Subframe reinforcement kits are very strongly recommended to go along with these solid motor mounts to reduce the risk of damage to the subframe. The motor mount section of the subframe should be reinforced to prevent stress and failure of the subframe.

Adapt an N54 or N55 GS6-53BZ transmission to your M5x/S5x engine to unlock superior torque capacity and optimized gear ratios.

Engineered for the BMW enthusiast who demands more strength and better gear ratios, the Turner Motorsport Transmission Swap Flywheel Kit provides a direct solution for mating a modern N54 or N55 6-speed gearbox to your M20, M5X, or S5X engine. This kit bridges the gap between generations, allowing you to run a high-capacity GS6-53BZ transmission without the typical fabrication nightmares.

The technical core of this kit is our dual-geometry flywheel. By utilizing this specialized design, you can retain your engine-side stock starter while using the factory clutch and throw-out bearing from your donor transmission. This ensures a precise fit and a firm, factory-like shifting feel that can handle significantly more power than older 5-speed setups. To guarantee a fitment, we’ve included a precision drill guide for bellhousing alignment and a universal pilot bearing pin to simplify the installation process.

Features and benefits:

Compatible with the starter from your original motor.
Uses factory clutch and throwout bearing from the donor transmission (GS6-53BZ).
Comes with necessary tools and a provided drill guide to adapt the top transmission mounting holes.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This kit includes the transmission filter and gasket. This item fits the following BMWs: 1995-1999 E36 BMW M3 S50 S52
