Description

The 5-Speed Allison 1000 transmission used in the 2004.5-2005 2500 and 3500 HD Chevrolet Silverado and GMC Sierra equipped with the LLY Duramax earned their reputation for excellence largely because of the advanced electronic control provided by the TCM (Transmission Control Module). Changing that factory calibration is especially important when you modify your truck and/or install ECM Tuning. Custom TCM Tuning gives you quicker shift changes, smoother operation, and an overall better driving experience.

DuramaxTuner's Custom TCM tuning will decrease time between shifts and improve clutch holding capacity by increasing line pressure electronically. This will make a more durable, better feeling, and better driving transmission. It can also help keep the engine in the ideal RPM range to utilize all of its potential power. 5-Speed transmission tuning can be utilized to enhance performance of both stock and built transmissions.

What’s the difference between Mild and Aggressive Transmission Tuning?

Smooth Shift Points are the best choice if you . . .

  • Want a similar feeling shift schedule to stock
  • Have a near-stock truck with stock tire size and stock turbo 
  • Installed a Box Tuner
  • Use your truck as a daily commuter
  • Want to get the best fuel economy possible

Aggressive/Elevated Shift Points are the best choice for if you . . .

  • Have an upgraded turbocharger
  • Run 35”+ size tires
  • Prefer higher RPM operation or holding the gear longer
  • Installed custom engine (ECM) tuning 

 Why do you need TCM Tuning?

  • Works with any ECM Tuning to provide smooth shifting and superior driveability
  • Torque converter lockup strategy helps put power to the ground when you need it most
  • Improves clutch holding capacity with increased line pressure
  • Makes your truck feel more powerful
  • Prevents short-shifting in performance applications
  • Ensures your engine is operating within its preferred rev range / power band

TCM Tuning is especially important for trucks with:

  • Any ECM Tuning, Box Tuner, or Throttle Booster
  • Larger tires (35”+)
  • Modified turbo(s)
  • Built transmission
  • Any modification that impacts operating RPMs

Towing & Performance

  • Makes full use of the wider torque curve provided by ECM Tuning
  • Keeps your truck in its power band when lugging up a grade
  • Improved Acceleration - Quicker shifts mean less time between gears and more time putting power to the ground
  • Optimizes the benefits of your other aftermarket performance parts
