Slipping engagement, oil leaks at the gaskets or an overdrive that refuses to shift into a higher gear are classic symptoms when the J-type in a B20-equipped 140 or 164 starts to wear out. This category gathers wear and sealing parts to troubleshoot and rebuild the overdrive without replacing the entire unit.

The group includes o-rings and gaskets to stop leaks, bearings and lock rings for disassembly, as well as balls, plugs and nuts in the hydraulic and valve section. There is also a gearbox pad that absorbs vibrations and keeps the power transmission in place. A common checkpoint during a rebuild is precisely the seals and the oil level – leaking oil and contaminated hydraulics are often the reason why engagement becomes weak or fails entirely on a B20 car.
