6L80 valve body for 2006-2017, OEM and ready to install. Ships fast from the USA.
If your 2006-2017 Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Camaro or Corvette with the 6L80 is shifting harsh, flaring between gears, dropping into limp mode, or has thrown P0716, P0717 or P0751, the problem is usually inside the valve body and the control module bolted to it, not the gear sets. This listing is the complete assembly, OEM part number 24275873, with the TEHCM (Transmission Electro-Hydraulic Control Module) already attached so you are not pairing a separate module and hoping they talk to each other correctly.
The 6L80 has no external shift solenoids or a separate wiring harness running to loose solenoids the way older hydraulic transmissions did. Every shift and pressure solenoid, the pressure switches, and the transmission's onboard computer are built into the TEHCM, which clips directly onto the valve body. Line pressure from the pump routes through the valve body's bores and spool valves, and the TEHCM commands exactly how much pressure goes to each clutch pack to make 1-2-3-4, 3-5-R and 4-5-6 apply at the right time. Because the control module and the hydraulic valve body are a matched, function-tested pair here, you are replacing both failure points at once instead of guessing which one caused the complaint.
These are the same complaints General Motors addresses in Service Bulletin 22-NA-182 covering harsh shift, shudder and flare conditions on 6L80/6L90-equipped trucks and SUVs, and the same failure points detailed in Sonnax's writeup on GM 6L45/50, 6L80/90 no-movement conditions, where a worn clutch regulator valve bore plug produces the exact pressure-control codes listed above.
Before you replace the whole assembly, pull the stored codes with a scanner and check whether they point at a specific solenoid circuit or at input speed sensor signal loss, since a bad connector pin or wiring chafe can mimic an internal TEHCM fault. Our 6L80 Valve Body Problems: Symptoms, How to Test, and Replacement guide walks through the pressure and resistance checks that separate a true internal valve body or TEHCM failure from a wiring or connector issue, and our 6L80 Shift Solenoid Symptoms and Replacement guide covers what actually fails inside the module versus what only looks like a solenoid problem.
This assembly is listed for the 6L80 across 2006-2017 applications. GM revised the valve body and TEHCM several times over that span, so match the casting markings and connector style on your old unit, or send us your year, make, model and VIN before ordering to confirm this is the correct revision for your specific build. Browse the full 6L80 parts collection if you need to cross-check other valve body revisions or confirm which one your vehicle actually left the factory with.
Drop the pan, change the fluid and filter at the same time you install this assembly so that metal or friction debris from the failed unit does not immediately contaminate the replacement, torque the valve body bolts in the correct sequence to GM spec, and reconnect the TEHCM harness carefully since the pins are easy to bend. After installation, run the transmission's adaptive relearn procedure (a scan tool reset or the documented drive cycle) so the new module's pressure tables match your vehicle instead of running on the old unit's learned values. We carry a 6L80E Transmission Master Rebuild Kit with Filter if you are doing the fluid and filter service at the same time, and a dedicated GM ATF Filler Adapter to fill the 6L80 correctly through its side fill port, since this transmission does not use a dipstick.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The TEHCM is already attached to this valve body. OEM part number 24275873 is the combined assembly, so you are installing one matched unit rather than pairing a module and valve body from two different sources.
If P0717 is coming from a failed input speed sensor circuit inside the TEHCM or a worn valve body bore, yes. If the code is being caused by a damaged connector, chafed harness wire, or a bad sensor outside this assembly, replacing the valve body will not clear it, so check the wiring first.
The 6L80 uses Dexron VI ATF. You should change the fluid and filter whenever you replace the valve body, since old fluid often carries the debris that caused the original failure, and running that debris through a new TEHCM shortens its life.
Run the adaptive relearn procedure after installation. The TEHCM stores learned pressure and shift timing values, and without a relearn the transmission can shift harshly or inconsistently even with a good valve body installed.
The 6L80 went through multiple internal revisions across that range. Match your old unit's casting markings and connector style, or send us your VIN before ordering, since GM changed components within the 2006-2017 window and the wrong revision will not seat or connect correctly.
It is a bolt-in assembly accessible from the bottom of the transmission pan, so an experienced DIY mechanic with the correct torque sequence and a scan tool for the relearn can do this job. If you are not comfortable with transmission electronics or do not have scan tool access for the relearn, a shop is the safer route.
