Thread: Transmission acting weird during startup

So when I crank the car it starts perfect...When I shift into Reverse it feels like there is no pressure, but if I give it gas it goes in reverse no problem...When i shift from reverse into drive The RPMs go up to around 1200 (from 900) and the car wants to pull without any gas...It only does this when its a cold start...I just had this tranny rebuilt a year ago, and the fluid is still nice and bright red (and filled to a good level). I took it to the shop and they said there is nothing wrong, but I figured id ask some advice from you guys.

thought i would put my 2 cents in on this one... my car does the same thing minus me having to give it some throttle to get it into reverse. I was told to check the IAC on the throttle body and clean it. I plan on doing this later tonight. Ill let you know if this solves the problem

I'm having the same problem Having to give it gas to get it to shift into reverse from a cold start. It's actually freaked me out.
