Is Your GM Vehicle Shifting Erratically or Stuck in Limp Mode?
There’s nothing more frustrating than a vehicle you can’t rely on. If you’re dealing with harsh, delayed shifting, a check engine light that won’t go away, or your vehicle being stuck in one gear, a faulty Transmission Control Module (TCM) is the most likely culprit. This critical component is the brain of your automatic transmission, and when it fails, it can make driving stressful and unsafe. Our VIN Programmed GM T42 TCM 24234503 is the definitive, hassle-free solution to restore your vehicle’s performance and your peace of mind.

- Harsh or unpredictable gear shifts
- Vehicle stuck in “limp mode” (usually 2nd or 3rd gear)
- Delayed engagement when shifting from Park to Drive or Reverse
- Check Engine Light or Transmission Warning Light is on
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, P0753, P0758, or other solenoid-related codes

An Expert’s Insight: Why VIN Programming is Non-Negotiable
“As a technician with over 20 years of experience, I’ve seen countless drivers try to save a few dollars with a non-programmed module from a junkyard. It almost never ends well. Your vehicle’s transmission, engine, and even anti-lock brake system are all interconnected. VIN programming isn’t just about making the part work; it’s about loading the precise software and calibrations that allow the TCM to communicate perfectly with your specific vehicle’s other systems. Skipping this step leads to persistent error codes, poor performance, and sometimes, damage to the transmission itself. Our pre-programmed VIN Programmed GM T42 TCM 24234503 eliminates that risk entirely, giving you a dealership-level repair without the dealership price tag.”
Frequently Asked Questions
What exactly does a VIN-programmed TCM do?
VIN programming loads your vehicle’s specific software and calibration files onto the module before it ships. This ensures the TCM works perfectly with your engine, transmission type, and other electronic systems right out of the box, eliminating the need for additional, costly programming at a dealership.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a straightforward installation. The TCM is typically located in the engine compartment and is easy to access. The process usually involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Most installations take under 30 minutes.
Will this clear my check engine light?
This module will resolve the underlying electronic fault causing transmission-related trouble codes. After installation, you should disconnect the battery for 15 minutes or use a standard OBD2 scan tool to clear any stored codes. If the light was on due to the TCM, it will stay off.
How do I know for sure that my TCM is the problem?
The most common indicators are transmission-specific diagnostic codes (like P0700 series), being stuck in limp mode, and erratic shifting that isn’t related to low fluid levels. If you are experiencing these symptoms, the TCM is the most probable cause.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module, saving you the time and hassle of shipping it back.
