H&S Overdrive for Dodge 6.7L Cummins

Transmission Tuning unlock code for your 07.5-12 Dodge Cummins 68RFE! This is a very easy and economical way to help your 68 last. A finely tuned engine is worthless if that power cannot be transferred to the ground. In order to meet the high horsepower and torque output of the 6.7 Cummins engine, we have modified the transmission tuning software to better "put the power to the ground". H&S Overdrive software is specifically tailored to H&S engine tuning and will ensure that you get the best performance and reliability out of your transmission.

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.

Black Maxx, Mini Maxx, and XRT Pro owners will have the ability to load the H&S Overdrive Transmission software.
