6L80 Valve Body 2007, remanufactured and ready to install. Fits the 6L80. Ships fast from the USA.
A 2007 Silverado, Tahoe, Suburban, Yukon or Escalade running the 6L80 that starts shifting harshly, slips between gears, hesitates on engagement, or has a stored pressure or solenoid performance code usually needs the valve body, and 2007 was early enough in this transmission's production run that the original units are now old enough to have worn bores and tired solenoids. This is a standalone, remanufactured 6L80 valve body built specifically for 2007 applications, bench-tested before it ships.
The valve body is the hydraulic brain of the 6L80. Pump pressure enters the valve body and is routed through a network of precision-machined bores and spool valves that apply and release each clutch pack and band in sequence. On the 6L80 the valve body also carries the shift and pressure control solenoids that the TEHCM commands electronically, so the condition of the bores and valves inside the valve body directly determines whether each shift is clean, delayed, harsh, or missing entirely. On a 2007 unit specifically, the regulator valve bores and bore-plug retainers are the parts most likely to have worn enough to leak pressure after this many years of service.
Sonnax's technical writeup on GM 6L45/50, 6L80/90 no-movement conditions ties several of these exact complaints, including burnt clutches from a sticking 3-5-R clutch regulator valve, directly to bore and bore-plug wear inside the valve body rather than to the clutch packs themselves, which is why replacing the valve body resolves problems that look like a failing transmission but are really a hydraulic control issue.
Pull codes with a scan tool first. If you are seeing a specific pressure control or shift solenoid performance code alongside the shift complaint, that strongly points at the valve body rather than a mechanical clutch failure. Our 6L80 Valve Body Problems: Symptoms, How to Test, and Replacement guide covers the line pressure and solenoid resistance checks that confirm a valve body is the actual cause before you spend money on the part. If the shift problem is paired with a torque converter shudder specifically, also check our 6L80 Pump Failure Symptoms and Replacement guide, since a worn pump can produce similar symptoms and is a different repair.
This valve body is listed for the 6L80 in 2007 model-year applications. The 6L80 saw several internal revisions even within a single model year depending on build date and application, so match the casting markings and connector pattern on your original unit before ordering, or send us your VIN so we can confirm the exact revision your vehicle needs. You can check the full 6L80 parts collection for other year ranges and revisions if 2007 does not turn out to be the exact match your casting numbers call for.
Drop the pan and change the fluid and filter at the same time you install this valve body. Metal shavings or friction material from the worn-out original unit will still be sitting in the pan and the old fluid, and running that debris through a fresh valve body is a common way to shorten a good part's life right after installing it. Use Dexron VI ATF, torque the valve body bolts in the correct sequence to GM spec rather than just snugging them down evenly, and run the adaptive relearn procedure after the swap so the TEHCM's shift timing matches the new valve body instead of the worn-out one it replaced. If you are doing clutch work at the same time, our 6L80 Clutch Module and BorgWarner 6L80 Friction Clutch Module Kit are common pairings for a 2007 unit at this mileage, and our 6L80 Transmission Oil Pan Kit with Drain Plug and Filter covers the pan and filter side of the service.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This is the hydraulic valve body itself for a 2007 6L80. If your original unit's TEHCM is also bad, confirm separately whether you need a combined valve-body-and-TEHCM assembly or can reuse your existing module.
Harsh or flared shifts paired with a stored pressure control or shift solenoid performance code point at the valve body. Torque converter shudder alone, without shift timing complaints, is more often the pump or converter, which is a separate check.
Yes. Change the fluid and filter at the same time using Dexron VI ATF. Old fluid carries debris from the failed original valve body, and that debris will shorten the life of the new one if it isn't flushed out.
The 6L80 had internal revisions within single model years, so match your old unit's casting markings and connector style, or send us your VIN before ordering to confirm this is the correct revision for your specific build.
Yes, this unit carries a 1-year warranty as a remanufactured, bench-tested part.
You should run the transmission's adaptive relearn procedure after installation, which typically requires a scan tool capable of resetting adaptive shift values, or a documented drive cycle if your tool does not support a direct reset.
