2006 - 2007 GM 6.6L LBZ Duramax | Transmission Tuning by PPEIPP-LBZ-TT
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 – not cool and a fuel economy killer! For vehicles with larger turbochargers, ppei transmission tuning is a must to get the engine back into a 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 eliminated unnecessary slip in the torque converter – which also drives down heat in typical “unlocked” conditions.
We at PPEI take pride in our work and if there is anything you wish to have changed in your transmission calibration, we are here to make it fit your driving style - "Custom Fit"!
This can be installed with EFILIVE and HPTuners.
I wasn’t sure what to expect with these but it made my trans feel completely different. It holds each gear longer and feels way better than stock
Shifts alot better now 35 inch tires no more lugging in 6th gear and better converter lock up also seems to help shifting havent limped trans since the tune
All around great tunes ECU/TCM both are perfect and Thomas and Logan were very helpful would highly recommend.
Got the trans and computer tunes. Wow! Just WOW! The transmission shifts so well and perfect! The #2 turbo brake is very useful when towing and I get my best MPG 24mpg HWY on tune 3! Tune 5 really wakes it up. I think these tunes saved my transmission. A+++++++
amazing transmission tuning program. The changes come in very smooth as when it starts to slow down when losing speed. I recommend it 100%
