a friend of mine just bought a 93 stang with a 2.3 and it has some tranny issues.he said it will go into all the forward gears but will not go into reverse.when in the foward gears it doesnt pull very hard though. he also said that it has a leak.any ideas on what could be wrong with it other than being low on tranny fluid.can it be fixed easy or is it time for a new tranny?
