Sounds like you have a issue with the pressure regulator valve in the transmission. Thats very common on those when the pressure becomes too low you will get a delay or no reverse till you give the engine gas. It will also cause the transmission to slip and set incorrect gear ratio codes indicating a slipping clutch pack. The first thing you need to do is buy a transmission pressure gauge test kit if your going to fix this yourself. You will also need a air compressor to air check each gears clutch piston and the reverse servo piston. Otherwise you will have to take it to a transmission shop and usually theywant to take it apart and rebuild the transmission before testing anything.
