Hi there, Can anybody verify if an automatic transmission 4HP18 (by ZF) from Audi A6 can replace original 4HP18 in Saab 9000 MY 92? Mine began having problems with 3rd and 4th gear. Kick down is not working properly and while slowing down to almost a stop transmission begins to vibrate similar to a manual transmission in a high gear at a very low speed. It is similar while accelerating from a stop with a transmission in "D" position. Similar vibration occurs shortly after reaching around 20mph. While accelerating from stop and upshifting from "2" through "3" and "D" everything seems to work OK. Any ideas on how to solve it? Many thanx in advance.
Don
