I am the guy who is considering the purchase of a 735iL with the 4 speed Auto Tranny. I did an archive search on tranny problems and it seems like the 88's have the most problems. My potential car has 157,000 miles on it and in my test drive showed no obvious problems with it. However, I don't know if I can expect a major tranny repair sometime soon. If the 89's have a history of tranny problems I may decide to avoid this purchase. The car really seems nice though. Thanks in advance for any help or advice.
