Think my tc is going bad. It keeps unlocking when I mash the pedal to pass a car. I have a t/c for a 2001 4x4 Cummins. It's new never used. I wondered if anyone knows if it will work in my 05?. I posted in 3rd Gen but no reply. That forum is always really quiet to be honest. Hoping there's a good tranny guy here. Thanks in advance.
