Improve your 2001, 2002, 2003, 2004, 2004.5 or 2005 LB7 / LLY's reliability by utilizing our in-house designed and tested kit coupled with our established transmission tuning. We calibrate firmness and timing of shifts, so you’ll be guaranteed to feel the smoothness and better shift quality missing on the 5 speed Allison. If you’re like the rest of us here at Duramaxtuner using our trucks as daily drivers, the added gear helps take the wear and tear off your engine while cruising at high speeds. It keeps your RPMs at the most efficient curve of the rev range, giving it the best ride possible!

  • Take your '01-'05 Allison to another level by adding a sixth gear!
  • Custom TCM tuning for your specific truck
  • Double Overdrive = 14% RPM reduction
  • All new valve body, wiring harness, and solenoids
  • Gear indicator works on Edge CTS monitor
  • Works with high idle, retrofit tap shifters
