It's easy to restore and extend vehicle shift quality with Zip Kits. Uniquely designed Sonnax parts target the root cause of valve body complaints and stop critical circuit pressure losses in the most common problem areas of the transmission.

See what people are saying about Zip Kits:
I installed our first Zip Kit on a U140F, nice kit and additional information. What was really nice: to have at your fingertips the vacuum testing locations and the effects of the wear in that bore. Without this information I might not have vacuum tested and missed this problem. Nice kit, Sonnax."
We had a 2008 Range Rover diesel 157,500km with drivability issues. We stripped the v/b and fitted all components from Zip Kit, reinstalled v/b, new ATF and new filter, then road tested the vehicle home. Well done, boys, this Range Rover drives 100%. I didn't even reset the adaptation, it drives real good."
