I think it's unlikely that it's a transmission problem. You don't say what
it is, but 330i only had the 5 speed manual for the '00/'01/'02 model years.
The early years of the electronic throttle had a couple of problems - one
a new throttle potentiometer, which was mostly done under warranty. The
engine program tries to keep the same rpm, and sometimes glitches - I most
often see this (even though I've had the throttle replaced) from start in
FloydR '01 330xi
