Hello guys, I have 94 gmc 6.5 3500 with a 4L80. My problem is that I can put it in reverse. And push the accelerator sometimes it moves and sometimes it doesn't. There is no strange noises and the fun part is when I mash peddle to the floor with it in gear the engine does rev up. Shifting it to drive does the same thing but not as frequent. Any suggestions would appreciated.
