I'm having problems with my transmission. I own a 1968 Mustang with a C-4 transmission. The engine when it is cold will go into reverse with some hesitation, but not drive .When the engine is hot (or warm)it will go into drive fine, but not reverse. The car does not leak at all from anywhere and i recently changed the fluids and filters in the transmission. Occasionally on random days the car will have decent power, but mostly it lacks it. Does anyone have a guess as to what specifically it could be? Any help would be greatly appreciated

Check your band adjustment...???

 

Yep, take it to a tranny shop and have them check the bands. You may even have a pump going south.
