Shortly after i bought my truck i was driving and the overdrive stopped working. It ran about 2200 rpms or so at 55mph, when normal was at about 15-1600 . However the overdrive light did not blink or come on but you could hit the button and the light would come on then you could hit it again to shut it off.
Then a few days after it started going into overdrive again. Then about 2 months after that it happened again where it wouldnt shift into overdrive. This time the overdrive button did blink. Periodically this happens. Its been about 3 months since this has happened though.
The last time i had overdrive issues my reverse went out as well. Wouldnt kick into overdrive nor shift into reverse. Some days the reverse would work some days it wouldnt, as well as the overdrive. When in reverse it would back up about 10 feet then just stop n rev high rpms. I did realize if i didnt hit the gas pedal my truck would roll in reverse . Once i did hit it, it would lock up most of the time.
Truck has been perfectly fine for 3 months now w/o any work being done. I can go in reverse as fast as id like and kicks in overdrive each time. Any ideas to why this happened? torque converter maybe? idk about the reverse. Could these problems be related? sorry for the long explination.
