Looking for parts for your BMW automatic transmission or manual transmission? You'll find many of the parts available to service your BMW's transmission here. While internal transmission servicing and rebuilding should be done by professionals, there are a lot of things on the outside of the transmission that you can service or replace yourself. These include gearbox seals, o-rings, gaskets, automatic transmission filters, backup light switches, mounting bolts, flanges, collar nuts, screw plugs, Mechatronics, and more.

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

The ZF 320z S5D is a common swap choice among BMW enthusiasts due to its reliable and robust nature. Unfortunately, it does have a weakness. The detent pins and springs that live inside of the transmission are known to wear down over time, often causing the shift lever to lean towards the 5th gear position when in neutral.

This full-service kit consists of everything you need to replace the failing detents in your ZF transmission. The kit contains only Genuine ZF components, all of which are sure to provide you with smooth shifting and operation for years to come.

This kit includes the following items:

3 Shift Pin Kits - 23117525048
2 Slide Bushings - 23117533395
2 Gearbox sealing lids - 23311224825
1 Shifter detent pin - 23311224849
1 Shifter detent pin - 23317502165
2 Lock Rings - 23317531374
3 Spring Retention Plates - 23317637524
5 Detent Drift/Punch Tools - 054834LA01AKT
Remedying the ZF's detent issue is a must for any enthusiast planning to get the most out of their transmission. Proper centering is essential for quick and smooth shifting, both being desirable features in any application. This kit is easy to install with several DIY guides existing online. A set of "drift" tools are included for proper installation.

Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Automatic transmission Level II kit contains what you need to do an automatic transmission fluid and filter service. For limited time includes a FREE bottle of Redline WaterWetter®! WaterWetter® is a unique wetting agent that reduces coolant temperatures by as much as 30°F. Pour it into your cooling system to provide rust and corrosion protection in plain water for racing engines, and to improve coolant heat transfer properties. Add it to new or used antifreeze to improve the heat transfer of both ethylene and propylene glycol antifreeze/coolants. Compatible with aluminum, cast iron, copper, brass and bronze components. Kit Includes: Automatic transmission filter with hardware Oil pan gasket Drain plug with sealing washer Fill plug with sealing washer 8 quarts Redline D4 automatic transmission fluid FREE bottle of Redline WaterWetter®

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.
