Frequently Asked Questions
Do I need a mechanic to install this part?
While professional installation is always an option, many savvy DIYers can install this TCM. It’s typically located in the engine compartment on the LH side. The key is to disconnect the battery before you begin. Because it’s pre-programmed, the most complex part of the job is already done for you.
Will this part require any additional programming from a dealership?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before shipping it. This makes it a true plug-and-play solution, allowing you to skip the time and expense of a trip to the dealer.
How do I know for sure that my TCM is the problem?
The most common indicators are diagnostic trouble codes (like P0700), the vehicle being stuck in ‘limp mode,’ and erratic or harsh shifting that isn’t related to low fluid levels or mechanical failure. If you’re experiencing a combination of these symptoms, a failing TCM is the most likely culprit.
Is this a genuine GM part?
This is a high-quality replacement module built to meet or exceed OEM (Original Equipment Manufacturer) specifications for fit, form, and function, ensuring dependable and long-lasting performance.
What happens if I continue driving with a bad TCM?
Continuing to drive with a faulty TCM can lead to more severe and expensive mechanical damage to your transmission. Poor shifting can cause excessive wear on clutches and bands, and incorrect line pressure can lead to overheating. It’s best to address the issue promptly to avoid a much larger repair bill.
Do I need to return my old part?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle, making the repair process simpler and more convenient for you.
