6L90 valve body for 2006-2017, remanufactured and ready to install. Ships fast from the USA.
Not every 6L90 valve body job needs the GM-branded unit. This aftermarket 6L90 valve body covers 2006-2017 applications and is remanufactured with the same corrected valves and bore work that fix the hydraulic root cause of harsh shifts, wrong-gear starts, and torque converter clutch codes, at a lower price point than an OEM-branded assembly.
The 6L90 valve body is a hydraulic casting, not a computer, so there is no firmware or branding difference that changes how it functions. What matters is whether the regulator valve bores, clutch boost valves, and bore plugs were corrected and function-tested before it shipped. This unit is remanufactured and tested the same way, which is why it can cost less than a GM-sourced assembly while fixing the same failure.
These are the same failure points covered in our 6L90 valve body wear guide, which breaks down which worn bore maps to which symptom.
A stored pressure-control or solenoid code with otherwise clean fluid points at the valve body. If the fluid is already dark and burnt, the clutch packs are likely damaged too, and a valve body alone will not resolve a slip that far along. The 6L90 common problems guide covers the full failure list on this transmission, including the TEHCM and converter shudder issues that often get confused with a bad valve body.
This listing spans a wide production run, and GM made running changes to the 6L90 valve body during that time, so match your original unit's casting number and connector count before ordering, or send your year, vehicle, and VIN and we will confirm the correct version. The full lineup of 6L90 valve bodies by year, including the OEM-branded versions, is on the 6L90 parts page.
Drop the pan, disconnect the internal harness and manual valve linkage, and lower the unit straight down to keep the check balls seated. Fit a new filter and pan gasket, torque the bolts to GM's sequence and spec, and refill with Dexron VI ATF. Because the 6L90 is electronically controlled, let the adaptive relearn run over the first several drives after install, or reset adapts with a scan tool. If the original solenoids are getting old, pair this valve body with a solenoid kit, and if the clutch packs behind it are worn, a clutch drum addresses the next most common 6L90 failure point.

Yes, when it has been remanufactured with corrected valves and function-tested, which is how this unit is built. The valve body is a hydraulic casting, so there is no firmware difference between brands.
It is built and function-tested the same way but without the OEM part markup. The hydraulic correction is what fixes the shift problem, not the brand stamped on the casting.
It covers that production span, but GM made running changes during those years. Match your original unit's casting number and connector count first, or send us your year, vehicle, and VIN.
If the code was caused by a worn pressure-control circuit or a leaking bore plug in the valve body, yes. If a solenoid itself has failed electrically, pair it with a solenoid kit.
Check the fluid condition and pull codes first. Clean fluid with a pressure or solenoid code points at the valve body; dark, burnt fluid usually means the clutch packs need attention too.
