Please Note Before You Buy: This will NOT work with the V2 H&S unit. This sale is final. Please read the listing carefully to make sure this applies to your vehicle/tuner. ----- 2006-2012 Dodge Cummins 48/68RFE - Prolong the life of your automatic transmission with H&S's Overdrive Transmission software. This code unlocks the ability to build a custom transmission tune to compliment the engine tuning on H&S Mini Maxx or XRT Pro tuners. Once you have read ALL of the product info BELOW and are ready to purchase, then please enter the LAST 6 digits of your Dodge Cummins's VIN number as a note when completing your purchase. 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). One of the biggest complaints about the stock 68RFE transmission is the early shifting. 5th and 6th gears will come in early and cause a "dead pedal" or even a transmission "shudder". These conditions worsen with performance engine tuning and can cause unnecessary damage to your transmission. H&S modifies those 5th and 6th gear shift points to greatly reduce these annoying problems. 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. This unlock code is provided to you within a few hours of receiving your VIN. We cannot complete your order without the last 6 digits of your VIN! Vehicle Applications: 2006-2012 Dodge Cummins 5.9L/6.7L 48/68RFE (2500/3500 only)
