Transmission slip? not sure
I have a 2003 Ford Ranger Edge FX2 4.0 Auto. Just changed the engine and as soon as i have it running the transmission seems to be slipping, I think. It shifts fine but when i get around 40mph, 2000rpm it seens to be slipping. i can give it gas and it will smooth out until the engine itdels back to around 2000rpm driving.If I take off fast or floor it it shifts through all the gears fine.just does it on a normal smooth drive.
