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.

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

Red Line 70W/80W GL-4 MTL gear oil (SAE 5W30/10W30 engine oil viscosity) designed for use in BMW manual transmissions. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. The MTL can be used as a replacement for the factory MTF or MTF-LT2 used by BMW. Add MTL to older BMWs that have become tough to shift will restore shift smoothness. Many experts agree that this is best lubricant to use in BMW manual transmissions. Sold by the quart.

Red Line 75W90 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/90 is the weight most commonly used in BMW differentials since the 1960s, including the factory clutch-type limited-slip diffs (exceptions being M3/M5/M6 cars since 2001). We use 75W90 in nearly all BMW chassis and the custom differentials that we sell. It's great for the street where the polyol-ester base has natural lubricity and friction modifiers lead to smoother and quieter operation with lower operating temps than the factory fluid. We also use it in some track cars that don't already use the more aggressive 75/90NS fluid (without friction modifiers).

Recommended or exceeds specifications for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763. Matches the specifications for the factory BMW SAF-XO diff fluid (#07512293972).

RED LINE MT-90 is designed to provide excellent protection and improved shiftability for manual transmissions and transaxles. MTL and MT-90 have cured the problem of hard shifting in numerous transmissions which have notoriously difficult shifting. The secret to their success is two-fold. First, they have the appropriate coefficient of friction for most manual transmission synchronizers. Many gear oils, engine oils, and ATFs are too slippery for proper synchro engagement. Secondly, the viscosity characteristics of MTL and MT-90 allow proper shifting over the entire temperature range which the transmission will experience. The synthetic base oils used have a very high viscosity index which provides relatively constant viscosity as temperature changes. MTL is a low 75W, almost a 70W, at very low temperatures and a high 80W, nearly an 85W, at elevated temperatures, providing adequate viscosity to prevent wear and deaden gear noise. MT-90 is a thicker 75W90 version of MTL. The shear stability and oxidation stability of these products are excellent, thus the physical characteristics of Red Line MTL and MT-90 will change little with use.

Red Line 75W140 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/140 is a specialized weight used for BMW M3, M5, and M6 models with the M Variable limited slip diff (all M models since 2001). Red Line fluid is used in nearly all E46 M3, E92 M3, E60 M5 we service as well as the custom differentials that we sell. It's great for the street where the polyol-ester base has natural lubricity and friction modifiers lead to smoother and quieter operation with lower operating temps than the factory fluid. We also use it in the track cars we build and prep. It may also be used in other specialized situations where a regular 75/90 will be too thin at elevated temperatures and your diff builder has approved a heavier weight oil.

Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360. An alternative to the very expensive factory BMW SAF-XJ+FM diff fluid (#83222282583).

Metal particles can accumulate due to various conditions such as normal wear, machining operations, casting flaws, and stress usage, leading to excessive wear of vital components. ECS Tuning's Magnetic Plugs help alleviate this concern by trapping these particles, thus safeguarding the internal components of your drivetrain. With a convenient 17mm hex head design, these plugs eliminate the need for special tools required for OEM plugs.

Key Benefits:

  • Removes abrasive metal particles from drivetrain fluid
  • Prevents excessive wear to internal components
  • Meticulously engineered for a perfect fit
  • Features a permanent magnet for efficient particle capture
  • Convenient 17mm hex head design for easy installation

We don't believe in "lifetime fluids". With BMW transmission life seemingly becoming shorter with each generation, we think it's just good-ole' common sense to replace the fluid at regular intervals (35-50,000 miles). Let's face it: transmission fluid at 50, 70, or 100,000 miles is not going to be as effective as when it left the factory. And if you drive your BMW like a driving machine and not like hearse, you'll want the extra protection that regular fluid changes offer.

In our TMS Service bays we use Red Line Synthetic Oils. Theyhave been enormously effective on the racetrack - helping us to win dozens of races and championships. And their track-record on the street is second-to-none. Red Line Oil is designed not to be a 'lifetime' fluid with compromises inperformance made for longevity. Red Line is simply designed to be the best lubricant you can use in any application. Red Line D4 ATF oil meets the requirements where Dexron III and Mercon fluids are specified. The 75/90 gear lube exceeds API GL5 standards.

We have been using Red Line Oil in our street cars and race cars for years. Hands-down, it is the Number One brand of high performance lubricant for BMWs. We put Red Line Oil in our 80,000 mile street M3 and noticed smoother shifts, especially on 1-2 and 2-3 shifts. Also, our short shift kit is less notchy! For our E46 M3 racecars we used RedLine in the transmission and diff. Some of our races can go as along as 6 hours and we're happy report outstanding results. To clear up any confusion this package is what we recommend for the E46 M3. Not only do we not believe in 'lifetime' fluids, we believe that Red Line fluid will give you smoother shifts and as good or better protection for your transmission and diff internals than the factory fluids (factory fluid is also not available in a quart-sized container - we've tried).This package includes two quarts of ATF D4 and two quarts of 75/140.

A sloppy shifter is one of the common complaints of older BMWs. In addition to the shifter linkage the transmission mounts contribute to rough and clunky shifting. BMW transmission mounts are rubber and get softer over time. This allows the transmission to dance around which changes the geometry of the shift linkage and could make it harder to shift. These urethane transmission bushings are stiffer than the stock rubber mounts and won't let the transmission shift around as much. The round design also has more surface area than the stock mounts which helps spread the load. Because the urethane is stiffer, expect more vibration to make its way into the shift lever area. Engine motor mounts should also be considered as a cause for driveline vibration, transmission movement, and poor shifting. Consider replacing your motor mounts at the same time as your tranny mounts.

Price is for the pair of transmission mounts with hardware.

A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. Recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90. We have been using RedLine Oil in our street cars and race cars for years. Hands-down, it is the Number One brand of high performance lubricant for BMWs.

Synthetic D4 ATF is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. ATF D4 is similar to Red Line's MTL formula and can be used in many BMW manual transmissions where MTF or MTF-LT2 is called for. The D4 ATF provides significantly improved gear protection than most OEM oils. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure.

Features:

  • Provides G-4 level gear protection (suitable for transmissions and transaxles, like the Corvette T-56).
  • Provides smooth and consistent shifts.
  • More stable than petroleum fluids; suitable for extended drain intervals.
  • Does not varnish at high temperatures.
  • Improved cold weather characteristics.

    This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability.
