- The vehicle being stuck in “limp mode” (often 2nd or 3rd gear).
- An illuminated Check Engine Light or Transmission Warning Light.
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- Failure to upshift or downshift, leading to poor acceleration and fuel economy.
- Complete loss of communication with the transmission.

An Expert’s Note on VIN Programming
Why is VIN-specific programming so critical? Your vehicle’s transmission behavior is governed by hundreds of parameters unique to its engine, axle ratio, and tire size. A generic or non-programmed module can’t account for these variables, often leading to persistent shifting issues or even damage. Our process ensures the programmed 24230461 TCM you receive has the exact factory calibration file for your vehicle, making it a true, reliable, and correct repair.
Installation & Fitment
Installation is straightforward for a DIYer or professional technician, typically taking less than 30 minutes. The TCM is located in the engine compartment, with common locations being on the RH side, next to the battery, or under the air cleaner box, depending on your model. Simply disconnect the battery, swap the module, and reconnect. We recommend using a scan tool to clear any stored fault codes after installation. With this programmed 24230461 TCM, you get a hassle-free fix for your GM truck, van, or SUV.
