How does Allison 1000 TCM Tuning help with towing?

TCM Tuning is the modification to the programming calibration of a Transmission Control Module (TCM).  Ever since 2001 when the Duramax was first offered in the 2500 and 3500 GMC and Chevy  HD truck it has been paired with the Allison 1000 transmission. 

These trucks are designed for towing and if you use it that way, you can probably think of a few ways you would like your transmission to act differently.  That is where TCM Tuning may be able to help.

Common Complaints About Stock Transmission Tuning:

  • "When I try to pass and I am in 6th gear, it is very reluctant to downshift."
  • "While merging on the express way it seemed to take a long time to get from one gear to the next. It's even worse with a trailer on."
  • "Even with tow haul mode on the truck doesn't seem to shift well since I put these larger tires on."
