I have a 77 F150, 351V8, rear wheel drive, C6 transmission. You can pull up to a stop sign and it will slip in 1st gear. You gas it to pull off, the engine turns, then the gear grabs. Ideas?
You stop at a light still in drive, you pull off and the engine starts to spin but
the transmission grabs after that. It is around a second after you hit the gas. I
have changed the transmission module, and really don't know what else to do.
