Thanks for the tips. Was the tranny replaced by the dealer or you had to pay for it?

Is the tranny covered under the CPO? My car has 70K miles on it.

Sometimes, the hydraulic system in these cars can accumulate moisture over time and or, the fluid gets dirty- this can cause the clutch to not disengage properly which can create the notchy feeling you are getting.

Both of those things are super cheap to do and should be done first. It cant hurt!

Then, if that does not fix the issue, it could be the clutch. Worst case scenario, the transmission...

I replaced the trans in my 08 m3 at 5200 miles!!!! due to a bad 2nd gear syncro
