After 3D scanning a lot of gearboxes we found that almost every gearbox had its own dimensions. Different bore sizes, mounting bolt size, hole of sets, no hole ofset. Not sure what the ZF engineers been up to be honest.
So we ended up with three different designs, all verified on the following gearboxes so far
Most probably they fit any other BMW 8HP gearbox as well, just send us a message and we will help you out.
It is important to note that the transmission fluid should not exceed 140°C.
