Our ZF Transmission Detent Repair Kit is the ideal solution for a very common, but easy-to-fix, problem with the 5-speed ZF transmission used on the E36 328i/M3, E46 328i, E46 330i, Z3 2.8/3.0i, Z4 2.5i, and MZ3.

Does your shifter have a problem returning to center? Does it get stuck around the 1-2 gate or 5th? Or does the shifter seem to resist going between gears? If so the problem lies with worn detent springs and pins inside the transmission. It's a well known problem that not only affects ergonomics but can lead to mis-shifts, especially on track. This kit solves that potential costly problem...

Proper centering of the shifter, and having it remain in a consistent spot, is critical for hitting the right gear during spirited driving or while on track. The problems are exacerbated in track and race conditions while the transmission shifts and twists under load (stiffer or solid bushings are a must!). As the transmission and shift linkage bind up the likelihood of a over-revving mis-shift increases substantially. While the BMW ZF 5-speed transmission is incredibly durable, this is a common issue for high-mileage transmissions, and you should plan on including this kit in any track preparation. Our kit helps to restore proper action for improved shifting accuracy, making your transmission feel new again.
