looks like I need new tranny for 325ci with 146K on it. Car is running good but when car is run for 20 min or more and stopped for 15-20 and shut off - on restart and in D or R - heavy shift where it really thuds in the rear thru the automatic gear changes. Never happens on cold start.

mechanic witnessed but quoted $4700 for rebuilt tranny out of CA - 2 year warrenty and includes parts and labor. Some opinions think this is high. I really could use some advice here. Been reading that this is typical for 3 series with even less miles than me.
