Restore Flawless Shifting and Performance in Your GM Truck or SUV
If you’re dealing with the frustration of a transmission that slams into gear, hesitates, or refuses to shift properly in your 2015-2016 GMC Yukon XL 1500, the Transmission Control Module (TCM) is the most likely culprit. As the electronic brain of your transmission, a failing TCM can turn a smooth, powerful ride into an unpredictable and stressful experience. I’ve seen it countless times in the shop: a perfectly good transmission crippled by a faulty module, leading to check engine lights and limp mode that leaves you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the biggest headache out of the repair process. Instead of you paying for an expensive tow to the dealership and then hundreds more for programming, we handle it all for you. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the latest, most stable GM software specific to your Yukon XL. When it arrives at your door, it’s truly plug-and-play.
Why Choose a Pre-Programmed 2015-2016 Yukon XL TCM?
Modern transmissions, especially the 8-speed (M5U) and 6-speed (MW7) units found in these GM vehicles, are incredibly complex. The TCM orchestrates every shift with precision based on data from dozens of sensors. When it fails, communication breaks down, leading to the issues you’re experiencing. Our solution directly addresses this by providing a reliable module that’s already synced to your vehicle’s specific configuration. This ensures all transmission parameters, shift points, and torque converter lockup strategies work exactly as the factory intended, restoring the smooth operation you expect.
Case Study: The ‘Limp Mode’ Yukon XL
A customer brought in a 2015 Yukon XL stuck in what we call ‘limp mode’—it wouldn’t shift out of 3rd gear. The dashboard was lit up with a ‘Service Transmission’ warning and the check engine light. A scan revealed code U0100 (Lost Communication with ECM/PCM) and P0700 (Transmission Control System Malfunction). The owner feared a complete transmission rebuild costing thousands. After verifying the wiring and connectors were intact, we identified the TCM as the point of failure. Instead of a costly dealer part and programming fee, we installed one of our pre-programmed modules. The entire swap took less than 30 minutes. After clearing the codes, the Yukon shifted perfectly on the test drive, saving the customer over $800 and a week of downtime.
Is Your Yukon Exhibiting These Transmission Issues?
- âś” Harsh or delayed shifting, especially between 1st and 2nd gear.
- âś” The vehicle feels like it’s starting in the wrong gear.
- âś” Getting stuck in one gear (Limp Mode).
- âś” A ‘Service Transmission’ or ‘Shift to Park’ message on the dash.
- âś” Check Engine Light with transmission-related codes like P0700, P0606, or U0100.
- âś” Unexplained hesitation or jerking during acceleration.
- âś” Inaccurate gear indicator on the instrument cluster.
A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.
- âś” Locate the TCM: On the 2015-2016 Yukon XL, the TCM is typically mounted on the driver’s side (LH) of the radiator support or fan shroud. It’s a silver box with large electrical connectors.
- âś” Disconnect the Module: Carefully release the locking tabs on the electrical connectors and pull them straight out. Be gentle to avoid damaging the pins or wiring harness.
- âś” Remove the Old TCM: Unbolt the old module from its mounting bracket. You’ll likely need a basic socket set for this.
- âś” Install the New TCM: Mount your new, pre-programmed module in place of the old one and tighten the bolts.
- âś” Reconnect Everything: Firmly plug the electrical connectors back into the new TCM until they click into place. Reconnect the negative battery terminal.
- âś” Final Steps: Start the vehicle. The check engine light may still be on. It’s recommended to clear any stored diagnostic trouble codes (DTCs) with a standard OBD2 scanner. Take the vehicle for a test drive to confirm smooth shifting.

Frequently Asked Questions
Do I need to take my vehicle to the dealer for programming after installation?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This makes the installation a simple plug-and-play process, saving you time and money.
Where is the TCM located on my 2015 Yukon XL?
On the 2015-2016 Yukon XL 1500, the Transmission Control Module is located on the driver’s side (LH) of the radiator.
What information do you need from me to program the module?
After you place your order, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we have this information to ensure correct programming.
Will this fix my transmission’s harsh shifting and check engine light?
A faulty TCM is the most common cause of erratic shifting, limp mode, and transmission-related fault codes (like U0100 or P0700) on these vehicles. Replacing it with this pre-programmed unit is the definitive solution for these specific electronic failures.
Is this part compatible with part number 24276411?
Yes, this module is a direct, interchangeable replacement for both 24272004 and 24276411.
