The A518 in my 92 is really actin up. I just put the truck back together after buying it wrecked so i don't know much about it.
When i shift from neutral to drive or reverse the truck pretty much stalls under its own power. It will move if i get tricky with the throttle but it's basically runnin like a locked up converter would. I know that the 518 has a non-lockup TC and all the linkage seems to be fine and im pretty much clueless now. Could it be something stuck in the valve body? The truck did sit for almost 2 yrs. Im gettin really frustrated with it so any help would be appreciated. Thanks in advance.
