68RFE MM3 Tuning

Extend your transmission life and increase your fuel economy with PPEI Transmission tuning! A MUST for tuned trucks with additional torque. The refined shift points get rid of the low RPM "lazy" feel these trucks have that force the driver to stab the throttle for a downshift. For vehicles with larger turbochargers, PPEI transmission tuning is a must to get the engine back into an RPM range to match the torque curve of the new turbo. Along with the improved shift points, PPEI also refines the torque converter lockup strategy to put the power to the ground much more efficiently for improved fuel economy by eliminating unnecessary slip in the torque converter, which also drives down heat in typical "unlocked" conditions. Lastly, the increase in line pressure PPEI provides increases the holding capacity in the transmission by clamping the clutch packs together with more force, allowing tuned trucks (or trucks towing heavy) to have the confidence they need to enjoy their truck for years to come. This tuning package can be installed using an EFILive AutoCal V2/3, FlashScan V2/3, HPTuners MPVI2/3 or EZ LYNK AutoAgent 2/3.
