6L80 Valve Body, remanufactured and ready to install. Fits the 6L80. Ships fast from the USA.
Chevrolet and GMC trucks, SUVs and performance cars built on the 6L80 all share the same complaint list when the valve body wears out: harsh or flared shifts, slipping, a torque converter that shudders under light throttle, and a check-engine light with a solenoid or pressure code behind it. This listing is a remanufactured 6L80 valve body, bench-tested and ready to install, built for owners who are replacing the part across the full run of 6L80 production rather than one narrow year range.
GM used the 6L80 from 2006 through 2020 across the Silverado, Tahoe, Suburban, Camaro, Corvette and GMC Sierra, Yukon and Cadillac Escalade, and revised the valve body's internal castings and connectors more than once along the way. Because this listing is not broken out by a single year range, confirming the exact casting and connector match before you install it matters more here than it does on a narrow-year listing, and is covered in the fitment section below.
Line pressure from the pump arrives at the valve body first. From there, a field of precision-machined bores and spool valves routes that pressure to apply each clutch pack and band in the correct order, and because the 6L80 is electronically controlled, the same unit carries the shift and pressure control solenoids the computer uses to time every shift. Wear in the clutch regulator and boost valve bores, not a single blown part, is what causes most of the shift-quality complaints owners bring to a shop.
Our 6L80 common problems guide covers the seven failure points that actually show up on this transmission, and our valve body testing guide walks through confirming the valve body specifically before you buy one.
Because this listing spans the full 6L80 production run, pull your original valve body and read the casting number off the main housing before ordering, or send us your year, make, model and VIN and we will confirm the correct match. The connector count on the internal harness and the separator plate pattern also changed across the run, and both are quick visual checks against the unit already in your vehicle. Every 6L80 part we carry, including versions broken out by specific year range, is listed on the 6L80 parts page if a narrower match fits your build better.
Drop the pan, disconnect the internal harness connector and manual valve link, and lower the valve body straight down so the check balls and accumulator pistons do not fall out of their bores. Replace the fluid and filter at the same service with fresh Dexron VI ATF, torque the bolts in GM's specified sequence, and let the computer relearn shift adapts over the first several drives. If the pressure switch assembly in the TEHCM is original and showing age, a pressure switch repair kit addresses that wear point in the same job.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Pull your original valve body and read the casting number off the main housing, or send us your year, make, model and VIN. The 6L80 valve body changed castings more than once across 2006-2020, so matching the casting is more reliable than matching by year alone.
No, this is the valve body casting assembly, remanufactured and bench-tested. The TEHCM and solenoids are separate parts; test them on their own if you have a solenoid performance code.
Dexron VI ATF. Change the fluid and filter at the same time you install the valve body so debris from the old unit does not circulate through the new one.
Clean fluid with a slip or delayed engagement points toward the valve body rather than the clutches, which usually show burnt fluid when they fail. Our 6L80 common problems guide covers how to narrow it down further.
No. The computer relearns shift adapts over the first several drives, or a scan tool can clear and reset adapts sooner if you want the shift quality to settle faster.
