Enhance your driving experience and extend the lifespan of your Allison transmission with PPEI’s Transmission Tuning, specifically designed for the 2001 - 2004 LB7 Duramax. PPEI’s 5-Speed Allison transmission tuning is a game-changer for your LB7 Duramax, whether you seek optimal performance or overall reliability.

Key Features:

  • Adaptive Shift Strategy: Tailored to improve the overall performance of your LB7 Duramax’s Allison 5-speed transmission, our tuning adjusts shift points dynamically, ensuring a smoother and more responsive driving experience.
  • Refined Shift Points: Say goodbye to the low RPM "Lazy" feel. Our tuning eliminates the need for aggressive throttle inputs for downshifts, enhancing fuel efficiency and drivability, especially for trucks with larger tires and, most importantly, LB7 Duramax trucks equipped with aftermarket turbos.
  • Turbo Lag Reduction: Experience reduced turbo lag with optimized upshifts and downshifts, keeping your engine in the ideal RPM range for maximum efficiency and power delivery.
  • Torque Converter Lock-Up Refinement: Our transmission calibration fine-tunes the torque converter lock-up strategy, delivering power to the ground more efficiently. This not only boosts fuel economy but also reduces heat build-up in typical unlocked conditions.
  • Customizable to Your Needs: At PPEI, we understand that every driver is unique. If you have specific requirements or preferences for your transmission calibration, our team is ready to customize it to fit your driving style.

Incredible Tech Support

I should have ordered the transmission tune when I purchased the truck, it is incredible. I upgraded the injectors, added a 4" exaust, and an air dog lift punp, but the transmission tune feels best. The truck goes and just keeps going, smooth as butter. But it wasn't easy, I am not very computer savvy and struggled to load the program. Tech Support walked me through it, and even when I couldn't follow directions they stayed calm and helped me get my truck running better than factory!
