6HP26 transmission service - saturday fun

Send the valve body to a professional and have it vac tested at the same time, as well as new solenoids.

When I bought my zip kit I found a shop that could vac test it. They end up finding that a lube valve was also worn and replaced it at the same time. Very cost effective too.

You will be pleased, just follow the sonnax zip kit steps and read up on the zf boxes, some good tips there, plus also here on AULRO from others who have done the same.
