End Transmission Headaches and Get Back on the Road
Is your Saturn Aura, Chevy Silverado, or GMC Yukon suffering from erratic shifting, getting stuck in gear, or flashing a persistent check engine light?

Expert Insight: The Power of Pre-Programming
In modern vehicles, the TCM is the brain of the transmission, communicating constantly with the engine computer. When you install a generic, unprogrammed module, the car simply won’t know what to do, leading to immediate errors or a no-start condition. Our VIN programming service writes your vehicle’s unique operational data directly onto the GM T42 TCM 24239926 before it ships. This ensures perfect communication between components from the moment you turn the key, just like the original part from the factory.
Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s specific identification number (VIN) and the latest GM software onto the module before we ship it. This makes the TCM a perfect match for your car’s engine, transmission, and options, allowing for a simple plug-and-play installation without any need for a dealership visit.
Is this part difficult to install?
For someone with basic mechanical skills, installation is straightforward and often takes less than 30 minutes. The TCM is typically located in the engine bay. Always remember to disconnect the battery before starting the job to ensure safety and help reset the vehicle’s computer systems.
Will this fix my check engine light and error codes?
Yes, this module is designed to resolve the internal electronic faults that cause common transmission-related DTCs like P0700. After installation, we recommend using a standard OBD2 scan tool to clear any stored codes from the vehicle’s memory.
Where is the TCM located on my vehicle?
The location varies by model. Common locations include next to the battery (Silverado/Tahoe), on the LH frame rail (Aura/Malibu), or under the air cleaner box (Impala/LaCrosse). Your vehicle’s service manual can provide the exact location.
Do I need to send my old part back?
No. There is no core charge for this part. You can keep or dispose of your old module, making the process hassle-free.
