Is Your GM Truck or SUV Plagued by Transmission Problems?
There’s nothing more frustrating than a vehicle you can’t rely on, especially when it’s your daily driver or workhorse. If your Chevrolet Silverado, GMC Savana, or Tahoe is suffering from harsh, erratic shifting, getting stuck in gear, or flashing a persistent check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. Ignoring these signs can lead to more severe transmission damage and costly repairs. Get back on the road with confidence by installing our professionally programmed T42 transmission control module.
Common Symptoms & Your Direct Solution
A faulty TCM can manifest in numerous ways, disrupting your vehicle’s performance and safety. If you’re experiencing any of the following, this part is the definitive solution you need:
- Harsh or Delayed Shifting: Abrupt gear changes, banging into gear, or a noticeable lag when accelerating.
- Limp Mode Activation: The vehicle gets stuck in a single gear (usually 2nd or 3rd) to prevent further damage.
- Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dash.
- Diagnostic Trouble Codes (DTCs): Your mechanic finds codes like P0700, P0750, or other solenoid-related faults.
- Poor Fuel Economy: The transmission isn’t shifting at optimal points, causing the engine to work harder and burn more fuel.
This programmed T42 transmission control module is engineered to resolve these issues directly. Because it arrives pre-configured to your vehicle’s specific VIN, it restores the precise communication needed between your engine and transmission for smooth, efficient operation right out of the box.

An Expert’s Note on VIN Programming
Why is pre-programming so important? A blank TCM from a parts store is just a paperweight until it’s programmed by a dealer. That process can be costly and time-consuming. More importantly, we program your module with the latest software updates available from General Motors for your specific VIN. These updates often contain critical improvements that fix factory bugs, enhance shift logic, and improve transmission longevityโbenefits you won’t get from a simple ‘relearn’ procedure. This programmed T42 transmission control module ensures you’re getting the best possible performance from day one.
By replacing your old, failing unit with this reliable, pre-configured programmed T42 transmission control module, you’re not just fixing a partโyou’re restoring the dependability and performance of your vehicle. Don’t let transmission troubles keep you off the road. Order today and experience the difference a quality, ready-to-install part makes.
Frequently Asked Questions
What does ‘VIN programmed’ actually mean?
It means we load the module with the specific software and calibration files from GM that match your vehicle’s unique Vehicle Identification Number (VIN). This makes the module a direct, plug-and-play replacement, as if it came from the factory for your specific truck or SUV. No additional programming is required.
Do I need any special tools for installation?
Installation is straightforward for a DIYer with basic hand tools. The TCM is typically located in the engine bay and is accessible. You’ll need a socket set to remove the mounting bolts and care when disconnecting the electrical connectors. Disconnecting the battery beforehand is highly recommended.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, it’s important to have the vehicle scanned for other, more specific codes (like solenoid circuit faults) to confirm the TCM is the root cause.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep or dispose of your old module without the hassle of returning it, saving you time and money.
How do I know this is the right part for my vehicle?
This T42 TCM is compatible with a wide range of 2006-2014 GM vehicles equipped with 4-speed automatic transmissions like the 4L60E and 4L80E. Please check the compatibility list on this page or match the service number on your original part to the numbers listed in our description to ensure a perfect fit.
