I have a 72 gmc with a 350 and an auto tranny, a turbo 350 i think, and its been giving me grief. The lever that comes off of the drivers side of the tranny that rocks back and forth to shift gears keeps jumping off. The lever that connects the shift linkage to tranny seems to want to keep jumping off. this might sound confusing, but the bottom prong that the shift linkage connects to, which has a spring that seems to retain the linkage on the shaft, seems to be jumping. it only does it when i really drop the hammer and the rearend gets traction.I dont know if anyone has any clue what im talking about, but i really dont know what gives.I reconnected the linkage, and worked it back and forth for while, and wathced it. i took it for a spin, and the moment i really gave it to her, bang, it was off agin.Is one prong on the shift rocker supposed to be shorter than the other? my top one is shorter, while the bottom one is longer. Is this right? im really sorry bout the long post, but its really important. this thing is my only transport right now, so till i get it fixed its the good old footmobile. thanx alot guys. sorry if im confusin
thanx in advance
