H&S Performance Software Unlock, Dodge (2007.5-12) 6.7L Cummins
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". This condition worsens 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 use their existing units to load the H&S Overdrive Transmission software. Using the H&S downloads section, you will simply update your tuner (Black Maxx or Mini Maxx) to the latest software level (from the H&S website). Once the tuner is updated, the transmission tuning software is ready to be unlocked.
After this software is purchased, you will receive an e-mail from H&S Performance containing your H&S Overdrive Unlock Code. If you have not received your unlock code within 24 hours after purchase, please contact H&S customer service.
