Due to the design of the 6L80 / 6L90 TEHCM, it’s not possible to simply replace a failed component like a 6L80 / 6L90 pressure switch or solenoid. Instead, you have to install a remanufactured GM Transmission Control Module 24275873 to make sure that all of the components work together properly and wear at the same rate. There are of course, many aftermarket kits that say they can allow you to replace individual components on the TEHCM. But that will only offer a short-term fix, because other components within the TEHCM may be damaged or worn as well. If you replace say, a pressure switch. It will start operating in a much higher capacity than the other switches on the TEHCM, which can lead to increased wear and component failure.
What Transmission Do I Have?
The 6L80 / 6L90 TEHCM is located inside of the transmission on the 6L80 / 6L90 valve body. Objectively, it is a fairly simple repair: simply remove the transmission pan, remove the valve body, unbolt the TEHCM from the valve body and install the new one. But it does take a bit of experience to not damage anything on the valve body or inside the transmission during the install. You must also have the correct tools and a clean workspace to do the job. If you try to go to the cheap route and just replace an individual solenoid or pressure switch, you’ll have to pay the labor charge all over again when one of the other components fail. So if you want to keep your vehicle on the road for as long as possible. And avoid paying more money to fix transmission problems that could have been avoided, you should consider upgrading to a remanufactured GM Transmission Control Module 24275873 from a company like Street Smart Transmission.
Remanufactured GM Transmission Control Module 24275873
Each Street Smart Transmission 6L80 / 6L90 TEHCM build starts with a thorough test of the electrical and communications system. If the core fails, it’s either repaired or completely discarded. Next, all of the pressure switches are replaced with upgraded switches that can withstand heat, vibration and stress much better than the OE pressure switches. New solenoid retainers, filter plates, fluid conduits, pushrods, O-rings and connectors seals are also installed (each remanufactured TEHCM comes with all gaskets, seals and grommets that will be needed for the installation). Once complete, each remanufactured GM Transmission Control Module then undergoes an automated vehicle simulation test, that accurately re-creates on-road driving conditions. This ensures full functionality and a hassle-free installation.
