t/c won't unlock
I pulled up to a light this afternoon and noticed that my truck was acting funny, i looked at my pyro and it was creeping up to 800 degrees so i shifted into neutral and the temp came down. The light turned green and i shifted into drive and the truck died, I tried it 5 times and reverse worked so i backed into a lot and put the truck in 4 lo then the truck went foreward. I can drive in 4 lo and shift into 2 hi and everything is fine except that when i stop the pyro temps rise and i have to stand on the brakes to stay stopped. The t/c is not unlocking, is there an electrical problem or did i blow up a sprag or something? no codes no leaks and no warrenty on the t/c
