so, last night i was driving. i got off the freeway and slowed down. hit the gas and my rpms flared from 0 - 2500 several times. it was so hard it made my car jolt. wtf? is this my tranny trying to down shift and going out? god dammit... if so do you guys think it is under warranty? 2001 cls 85k auto. just had a new tranny put in 2 years ago.... again, god dammit.
