Buddy had a issue today with his truck. He said while on the highway a wrench light came on in the dash but everything was driving fine. He got off the highway and stopped at a red light. Once the light went green the truck would not accelerate in any gear. The RPM's would just shoot up but the truck would not move. He turned the car off and back on and was able to move the car in 1st until he came to a stop and the same thing happened. Any ideas?
