00 Monte Carlo 3.4L, I bought it 2 months ago and it started to whine kinda loud, sounded like PS but it was shifting solid and everything and then 3 weeks go by and it starts slipping on a cold start(just rev up until it gets warm and thinks its ready) put a new tranny filter in and runs good but still has whine...you wouldn't have to wait at all on cold starts to throw it in drive and go, now couple weeks go by and it starts doing the cold start issues again and now its slipping after every stop and go, and shifts hard and nasty into 2nd...3rd is fine....which should I do....I'm gonna drop the pan right now and report back... I'll also take vid of sound before I start the pan
