Restore Peak Performance to Your Allison Transmission
How does the VIN programming work?
After you complete your purchase, simply send us your vehicle’s 17-digit VIN. Our technicians will use it to load the latest, most compatible GM software onto the module. This ensures it communicates perfectly with your truck’s engine and other systems right out of the box.
Is this a plug-and-play part?
Yes! Because we program it to your VIN before shipping, no additional programming or dealer visits are required. You can install it yourself and be back on the road immediately.
What tools do I need for installation?
You’ll only need basic hand tools, typically a socket set to remove the mounting bolts and a wrench for the battery terminal. No specialized diagnostic equipment is needed.
Do I need to return my old TCM (core charge)?
This listing does not require a core return. You can keep your old part, though we always recommend recycling old electronics responsibly.
Will this fix my specific transmission problem?
This module corrects issues directly caused by a failing TCM, such as the symptoms listed above. While it is a very common point of failure, always ensure your vehicle has been properly diagnosed. Problems with internal transmission components or wiring will not be solved by replacing the TCM.
