6L80 Valve Body 2010, remanufactured and ready to install. Fits the 6L80. Ships fast from the USA.
A 2010 Silverado, Tahoe, Suburban, Camaro, or Escalade that shifts harsh, flares between gears, or drops into limp mode with a stored pressure code is pointing at the valve body before anything else in the 6L80. This is a remanufactured 6L80 valve body built for the 2010 model year, bench-tested before it ships so it goes in as one known-good assembly instead of a stack of individual valves and plugs you have to source and match yourself.
The 6L80 is a six-speed, electronically controlled transmission, and the valve body is where that control turns into hydraulic action. It routes line pressure from the pump through the pressure regulator and clutch boost valve, then through a bank of clutch regulator valves that each feed one friction element. The shift and pressure control solenoids that the TCM commands live on this assembly too, so a worn bore or a leaking end plug does not just cause a mechanical slip - it also throws the solenoid performance codes the computer reads as a hydraulic fault.
Our 6L80 valve body problems and testing guide covers how to tell a solenoid fault from a worn bore before you spend money, and the 6L80 common problems guide lists the other failure points that show up alongside a tired valve body on this generation.
Pull the codes first. A clutch pressure-control code (P0776, P0796, P2714, P2723) usually means a clutch regulator valve bore or its end plug is leaking, which is exactly what a remanufactured valve body corrects. If the fluid is already dark and burnt, the clutches themselves may be damaged and a valve body alone will not stop a hard slip - have that checked before you install. GM's service bulletin on harsh shift and shudder complaints on 6L80/6L90-equipped vehicles is a useful second opinion if your shop is debating valve body versus torque converter.
This unit is built to the casting and connector layout used on 2010 6L80 production. The 6L80 went through several running updates across its life, so a unit built for an earlier or later year can look nearly identical but not seal or plug in the same way. Match your original unit's casting markings and connector count against this one, or send us your year, vehicle, and VIN and we will confirm fitment before it ships. Every 6L80 valve body we carry by year, along with the rest of the parts for this transmission, is listed on the 6L80 parts page.
Drop the pan and change the fluid and filter at the same time you install this valve body, so debris from the old unit does not circulate through the new one - refill with Dexron VI, the spec fluid for the 6L80. Torque the valve body bolts in the sequence GM specifies rather than a simple criss-cross pattern, since these bolts carry different torque values by position. Because this is an electronically controlled unit, run the transmission adaptive relearn procedure after installation, either by driving it through a full range of shifts or with a scan tool reset, so the TCM retimes the shifts to the new hardware instead of carrying over old adapts. Pairing this job with a fresh pressure switch repair kit and a pan and filter kit addresses the other common wear points in the same hydraulic circuit while you are already in there.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This is the valve body casting assembly, remanufactured and bench-tested. If your original solenoids are original equipment and showing age or throwing their own codes, pair this with a solenoid or pressure switch kit rated for your year.
Pull codes first. Clutch pressure-control or solenoid performance codes point to the valve body; a shudder that only shows up under converter lockup with clean codes otherwise can also be a torque converter issue, so check both before ordering.
It is built to the 2010 casting and connector layout. The 6L80 changed across its production run, so match your old unit's casting markings and connector count against this one, or send your year, vehicle, and VIN and we will confirm fitment.
Not on its own. Burnt fluid usually means the clutches themselves have already taken damage, and the transmission needs a look at the clutches and a rebuild alongside the valve body rather than a valve body by itself.
No reprogramming is needed. Run the adaptive relearn by driving through a full range of shifts, or have a scan tool reset the shift adapts so the computer retimes shifts to the new hardware.
