The A40 Transmission Control Module found in the 2006-2008 2500/3500 Duramax is prone to failure. The internal circuit board fails and is not serviceable.  When this failure occurs you may observe messages such as Range Shift Inhibited, Service Brake System, Service Stabilatrak, or might experience loss of gear shift indicator on dash, slamming into Drive or Reverse, and DTC U0101 for loss of communication with TCM.

 

This repair at a dealership can cost upwards of $1000 and can take a couple days to get repaired.  Our TCM will have you back on the road quickly while saving you money.  Plus you'll receive a much better warranty.

 

Will Not Work in 4500 or 5500 trucks.

Awesome product and support. It was much harder to diagnose the problem of the failed OEM unit than it was to replace it. Watch the video and in less time it takes to watch it you’ve replaced it!
