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.

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.

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

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.
