Replace your failed transmission control module with an OEM 2001-2005 Chevrolet Silverado / GMC Sierra TCM, programmed to your vehicle before it ships.

This module is a direct replacement for units carrying part number 29537441. Every unit is refurbished, bench-tested against OEM specification, and flashed with the latest calibration.

Fitment note: Allison 1000 five speed.

Match the number on your existing module

These modules are identified by the part number printed on the label of your original unit. Read it and check it against the number above before ordering. If the label is unreadable, send us your VIN and we will identify the correct unit.

Confirm it is the TCM before you buy

Harsh shifting, limp mode or a transmission stuck in one gear are commonly blamed on mechanical failure, and owners pay for rebuilds that were never needed. Codes in the P0700 to P0799 range point at the transmission control system, and a complete loss of communication with the module on a scan tool is strong evidence the module itself has failed. Check fluid level and condition first – low or burnt fluid produces the same symptoms.

No core charge, and no core to send back

There is no core charge on this module, no deposit and nothing to return. Keep your old unit, and your lifetime warranty starts the day it ships.
