6L80 valve body for 2006-2017, remanufactured and ready to install. Ships fast from the USA.
Across the full 2006-2017 production run of the 6L80, the same hydraulic complaint keeps showing up: a harsh or flared shift, a torque converter clutch that shudders, or the transmission dropping into a limp-mode gear with a solenoid or clutch pressure code stored. This listing is a complete 6L80 valve body with the shift and pressure control solenoids already mounted and function-tested, built to cover 2006-2017 applications, so one part addresses both the hydraulic wear and the solenoids that control it instead of chasing the two separately.
The 6L80 is a six-speed, fully electronic automatic, and this valve body is where the transmission control module's commands turn into actual clutch apply pressure. Each solenoid mounted on the assembly controls one circuit - a shift solenoid, a pressure control solenoid for a specific clutch, or the torque converter clutch apply/release pair - and each of those circuits runs through its own regulator valve and bore inside the casting. Because the solenoids and the valve body bores work as one hydraulic system, a problem on either side produces nearly identical symptoms, which is why this part is sold with the solenoids already fitted and tested rather than as a bare casting.
Our 6L80 shift solenoid symptoms guide walks through telling a solenoid fault from a hydraulic bore problem, and the 6L80 valve body testing guide covers the bench and in-vehicle checks that confirm which side of the system has actually failed.
Pull every stored code rather than clearing and retesting - a pattern across more than one clutch circuit points to the valve body itself rather than one bad solenoid. GM's service bulletin on 6L80/6L90 harsh shift and shudder complaints is worth reading if a shop is deciding between a valve body replacement and chasing the torque converter. If you are not sure which 6L80 valve body fits your specific year and application within this wide a range, check fitment before ordering or send us your year, vehicle, and VIN and we will confirm the correct unit.
This assembly is built to the connector and casting layout common across 2006-2017 6L80 units. Because GM made running changes to this transmission over more than a decade of production, confirm your vehicle's exact application and connector count against this listing before installing, particularly if your vehicle is near the start or end of this range. The complete 6L80 lineup by year and part type is on the 6L80 parts page.
Drop the pan, disconnect the internal wiring harness, and lower the valve body straight down rather than at an angle to avoid dropping the check balls out of their bores. Change the fluid and filter at the same time, refill with Dexron VI, and torque the bolts in GM's specified sequence rather than a simple criss-cross pattern. Because the solenoids are new on this assembly, run a full adaptive relearn after installation - either by driving through a complete range of shifts or with a scan tool reset - so the computer times shifts to the new hardware instead of carrying over old adapts. Pairing this job with a pan, drain plug, and filter kit and fresh Dexron VI fluid covers the rest of what the service needs.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, the shift and pressure control solenoids are mounted and function-tested on this assembly, so you are not sourcing or matching them separately.
It covers the connector and casting layout common across that range, but confirm your specific year and application before ordering, especially near the start or end of the range, or send your year, vehicle, and VIN and we will confirm fitment.
Pull every stored code. A pattern of codes across more than one clutch circuit, or a fix that doesn't hold after a fluid service or solenoid swap, points to worn bores in the valve body rather than a single bad solenoid.
Dexron VI. Change the fluid and filter in the same job as the valve body swap so debris from the old unit does not circulate into the new one.
No reflash is needed. Run the adaptive relearn by driving through a full range of shifts, or reset shift adapts with a scan tool so the computer retimes shifts to the new hardware.
