I have the tendancy to shift to neutral alot at red lights. Also, I switch to manual mode a lot when trying to accelarate. When stopped at lights, I switch to neutral, and sometimes I let the car roll back before putting it in Drive. is this harmful for Trans? Sometimes I tend to start out in S3"3rd gear", rather than ED "Economy Drive", and I tend to switch to Drive and back to S3. And at time sI go to S2 to s3 to D. and M1 to M2 M3 M4. Am I messing up my Trans?! Hope not. It's less than year old, and I kinda used to do the same with the previous one, but not sure my driving habits made it go bad..it was the original on the car..91 525i and i bought it in 98. Replaced Trans in late 1999. I guess bottom line, does switching between the E, S, and M mode harmful? I am used to stick shifts, and I tend to play with this one like one. Any tips for making this Trans last a long time?
