Frequently Asked Questions
Is this TCM really plug-and-play?
Yes. We program the module to the specific Vehicle Identification Number (VIN) you provide during checkout. This ensures it communicates perfectly with your Avalanche’s other computer systems right out of the box, with no additional programming required.
Where is the TCM located on my 2007-2008 Avalanche?
On the 2007-2008 Avalanche 1500, the T42 TCM is typically located in the engine compartment, next to the battery. Always disconnect the battery before beginning the replacement process.
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 (like a faulty solenoid circuit inside the module), you should always diagnose any other specific codes that accompany it. After installation, be sure to clear all codes with a scan tool.
Do I need to return my old TCM?
No. There is no core charge or need to send your old part back to us. You can dispose of it at your convenience, making for a hassle-free repair process.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe issues. Poor shifting can cause premature wear on clutches and other internal transmission components, potentially leading to a much more expensive mechanical failure down the road. Addressing it early with a new 2007-2008 Avalanche 1500 TCM 24235732 is the smart choice.
