Hello e39-ers, thank you for welcoming an e46er over here. I have been enlisted to help a friend buy an e39 with an auto transmission. Disclosure: I know nothing about auto trannys (my e46 is MT).
Anyway, we took the car (2000 528i w/ about 150k) for a drive, and I wanted to give it some, ahem, spirited driving. Car felt and ran great, with one concern. At one point, first gear wound up as it does, and when it switched to 2nd, it felt as if it was vibrating for a few seconds, almost like something was slipping or trying to grab. The car ran fine, so it was in gear alright, but just for a few seconds, there was a vibration. I think it's transmission related because I only noticed it when the car would shift from a lower gear at a high rpm to the next gear. Could be a flex disc, I suppose, but then why would it only happen for a few seconds right when the car changed to a lower gear?
Any thoughts? Sign of a bigger transmission problem?
