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?

Asked by donnie222 Oct 05, 2015 at 02:36 PM about the Ford F-150

Question type: Maintenance & Repair

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.

Thanks for the idea Kelly. I have not tried fluid and filters yet. I just bought the truck about a month ago, and had to change the power steering, alternator, transmission module, oil, and some wiring. This is an automatic c6 tranmission. I think I forgot to say it was automatic. I'll try fluid and filters over the weekend.
