2002 xj8 120400 miles just changed the transmission fluid and filter. I drained fluid which was black so changed filter refilled then ran for 200 miles . decided to remove filter again and remove valve body cleaned everything put all back with new filter refilled with Pentosin ATF 1 now problem when I first put it in drive to go, it slips for the first 2-to 300 yards then it shifts great took on freeway no problems only dose it on cold start what did I do wrong.??? I never had a problem with the transmission before with the dirty fluid. any Idea what I did wrong thanks jrb53

 

Maybe the Pentosin doesn't work the same?

 

The Pentosin ATF 1 is the correct fluid. I use it in WV/Audi 01M and 01V as well as the ZF 5HP24.

Maybe the valve body was reassembled incorrectly and/or leaking somewhere???

Thanks Motorcarman I was thinking the same thing. just dreading getting under car again. will post when I have it done

 

Best of Luck, did you fit the modified valve in the gearbox?

 

Hi Stu no did not change anything. What modified valve are you talking about. is this something I need to do ???? never had any problems with tranny before changing fluid

I've got the Transgo valve ready to go in my car, it really is a recommended thing to do to preserve you from heartache later on. Best of Luck to you.
