If you own a diesel engine tuner, chances are that your transmission is being neglected and isn’t compensating for the increase of horsepower/torque, causing premature burnouts and costly repairs (we all know Dodge’s record).
If you are a 2006-2012 Dodge Cummins driver (2500/3500 only), then you’re in luck - the Cummins Overdrive transmission software will do just that. The transmission tuning software is already built-in to your tuner and can be activated simply by purchasing this unlock code.
No downloads are required - all the data is already inside your tuner. This code simply unlocks the ability to access it. Click on the appropriate manual for your tuner below to review details related to your specific year/model.
