Frequently Asked Questions
What does a pre-programmed TCM mean for me?
It means the module arrives ready for installation right out of the box. We use your vehicle’s VIN to load the latest GM software specific to your Express 2500. This eliminates the need for expensive and time-consuming programming at a dealership, making the repair process faster and more straightforward.
Do I need to send my old module back?
No. This part is sold without a core charge. You can keep your old part, saving you the hassle and cost of return shipping.
Will this fix a P0700 diagnostic trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause of a P0700 and related codes (like solenoid faults), you should always ensure the transmission’s mechanical and wiring components are in good condition. After installation, be sure to clear all codes with a scan tool.
How difficult is the installation on an Express van?
Installation is typically straightforward. On most Express vans, the TCM is located in the engine compartment on the right-hand side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Most mechanics or experienced DIYers can complete the job in under 30 minutes.
Is this compatible with other GM trucks and vans?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 GM vehicles equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L80E. This includes models like the Silverado, Sierra, Tahoe, Yukon, and Savana. We program it specifically for the vehicle you order it for.
