2009 ram 1500 transmission stuck in 4 gear
Just installed predatorX 87 octane tune. Now transmission is in 4 gear and won't shift. Reverted back to stock tune with no success.

Transmission is in limp mode. You'll have to clear the codes. If it happens again chances are you have a transmission issue and it's just a coincidence it happened after loading the tune.Vicinsa wrote: Fri Jul 24, 2026 2:51 pm Just installed predatorX 87 octane tune.
