Please Note:This is a highly complex repair most remanufacturers don’t have the capabilities or expertise to handle. Combined with the fact the part is on backorder from the dealer with no ETA, this has created a very high demand for this service.

Due to this demand, we are experiencing a backlog which is creating further delays. Our team is working hard to get as many of these modules repaired as possible, but please be patient.

Furthermore, there are some TCMs which have issues with the flash data. There’s no way of knowing if this is the case before testing. While there’s no additional cost to resolve these issues, it will take longer to resolve.

Features:

Plug & Play: The software and settings will not be modified, making this module plug and play. No software reload, coding or calibration is required after installation.

Completely Reworked PCB: All internal circuit boards are tested at the component level. Any known prone-to-failure parts that are close to the maximum tolerance are automatically replaced.

Quality Tested: All TCMs undergo rigorous tests on our specialized custom-built CAN-bus driven test bed. All functions, DTCs, and software are checked and verified for proper operation.

Lifetime Limited Warranty: This module comes with our Lifetime Limited Warranty. Please see here for more information.

TCM Flash Programming Failures

Flash memory corruption amounts to about 40% of Duramax Transmission Control Modules. As a result, the TCM will lose communication with the rest of the vehicle’s network. Such a failure means that the software in your TCM has crashed and can not be recovered. In these cases, we will replace the flash chip and reprogram it with software that matches your Vehicle Identification Number (VIN). This procedure is performed using the original GM TDS online service. Once this is completed, your TCM will be updated with the latest software available from GM. TCM TDS Re-programming is done at no additional cost to you. Re-programmed units are plug and play, as long as they are installed in the original vehicle.

This also means that if you had your TCM tuned by the outside company, your tune will be lost and the TCM will be restored to the factory software level. You can always opt to re-tune your module again after it is installed in the vehicle. XeMODeX is not responsible for any tuning costs. We will only program the TCM with the original factory software.
