When I shift into reverse it hesitates for a few seconds then slides in. This is not normal for my truck after it has warmed up. It has always went right into reverse with no delay and its shifted in hard every time, no slideing about it. Also it has felt like ive been driveing around with the brakes on.(yes I checked)It seems to shift fine going from 1st to od. Any ideas would be greatly appreciated.

Thanks, Mooseman
