A truck like your Silverado or Sierra is built for tough work and dependable performance, but a faulty Transmission Control Module (TCM) can bring everything to a grinding halt. If you’re experiencing harsh shifting, hesitation, or dashboard warning lights, you’re not just losing performance—you’re losing confidence in your vehicle. This pre-programmed TCM is the definitive solution, designed to restore your truck’s factory-perfect shifting and get you back on the road with peace of mind.
Common Symptoms of a Failing TCM & Your Direct Solution
A failing TCM can manifest in several frustrating ways. You might notice your truck slamming into gear, refusing to shift, or getting stuck in ‘limp mode’. Often, this is accompanied by a Check Engine Light or a ‘Service Transmission’ warning.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is essential because the Transmission Control Module must be programmed to communicate with the specific engine, electronics, and options package in your truck. This VIN-matching process ensures a seamless, error-free installation and proper transmission function.
Is this a simple plug-and-play installation?
Yes. Because we pre-program the module to your VIN before shipping, it is ready for installation right out of the box. No further programming or trips to the dealership are required. Simply have the old module swapped with this new one, and you’re ready to go.
What happens if I don’t replace a bad TCM?
Ignoring a failing TCM can lead to more severe problems. Continued erratic shifting can cause premature wear and internal damage to your transmission. It can also result in poor fuel economy, unpredictable performance, and the risk of being stranded if the vehicle enters limp mode or refuses to shift at all.
How do I confirm this part fits my vehicle?
This module fits a range of GM models listed in the compatibility chart, including the 2019-2020 Silverado 1500 TCM application. The most crucial step is providing your VIN. Our programming process verifies the exact fitment for your specific truck, guaranteeing compatibility.
Will this fix my ‘Service Transmission’ light?
In most cases, yes. If the warning light and associated codes (like U0101 or P0700) are caused by a failing TCM, this part is the correct solution to resolve the issue and clear the warnings from your dashboard.
