The most helpful product to date are your Zip Kits. Your Zip Kits hit the valve body issues right on the head. Thank you very much for this product.

Over the years of using Sonnax I have come to really appreciate the continual good work Sonnax puts into our industry and their products. The Zip Kit is my favorite product.
W. Swanson
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.
