Ok, so i replaced my 4l60e. While it was still on the jack stands I ran it through the gears, the wheels moved and everything seemed fine so I took it off the stands. Then I put it in reverse and the car wouldn't move so I ran through the gears again. Still nothing. I'm hoping you guys can give me some kind of idea whats going on. Thanks for any help.

 

How is the fluid level and is this a fresh build?

 

fluid is good trans was used

 

Pull a cooler line and make sure its pumping fluid.

 

ok ill do that but before i installed the trans i spun the converter to make sure the pump was pumping do you think a clogged cooler line would cause the prob? and thanks a lot for helping truble shoot this.
