trans won't downshift ?
My auto trans won't shift into first gear unless you use the gear shifter. The truck is throwing a vechile speed sensor malfunction code, and I was wondering if anybody could tell me if I have a bad throttle position sensor or is my trans about to go out. I also checked the fluid and it looks good. Any help would be appreciated.
