6L90E valve body for 2010-Up, remanufactured and ready to install. Ships fast from the USA.
GM revised the 6L90E valve body casting partway through production, and for 2010-and-up Silverado 2500/3500, Sierra HD, Express, and Savana applications the correct casting carries the 0955/0945 identification. This matters because an earlier-casting valve body can look like a fit and still miss internal passage changes GM made to the unit, so matching the exact casting is part of fixing the problem rather than an afterthought. This unit is remanufactured on the correct 0955/0945 casting and tested before it ships.
The valve body is the hydraulic control center of the 6L90E. It meters line pressure and routes it through precision bores to the clutches and bands that make each of the six gears, and because the 6L90E is electronically controlled, the same casting carries the shift and pressure-control solenoids the computer fires to time every shift. When those bores wear on this casting revision, the solenoid command still goes out correctly, but the oil pressure behind it arrives late or leaks off before it fully applies the clutch.
Our 6L90 common problems guide covers how these symptoms line up against the other known failure points on this platform, including TEHCM faults and converter shudder, so you can tell whether the valve body is the actual cause before ordering.
Check your old unit's casting marking against 0955/0945 before ordering; a visually similar valve body from an earlier model year can bolt on and still not resolve the symptom if the internal passages differ. The 6L90 valve body testing guide walks through checking line pressure and isolating a worn bore from a bad solenoid, and the 6L90 valve body wear guide covers the specific internal wear locations that produce delayed engagement and shift-quality codes on this generation.
This valve body is built for 2010-and-up 6L90E applications across GM's heavy-duty lineup: Silverado 2500/3500, Sierra HD, Express and Savana vans, plus the Camaro ZL1 and Corvette Z06/ZR1 that share the transmission family. Match the 0955/0945 casting marking on your original unit against this one before ordering, or send your year and VIN so we can confirm fitment, since an earlier-casting 6L90 valve body is not a direct substitute. Every 6L90 part we stock by casting and year is grouped on the 6L90 parts page.
Replace the fluid and filter at the same time as the valve body, since debris from the old casting circulating through the new one undoes the benefit of installing a correctly revised unit. Refill with Dexron VI ATF, torque the valve body bolts in GM's specified sequence, and run the adaptive shift relearn with a scan tool once reassembly is complete; skipping the relearn is a common reason a correctly matched valve body still shows delayed engagement on the first few drives. If towing load has already worn the planetary or clutch packs along with the valve body, pair this with a 6L90 planetary or a 6L90 clutch module rather than replacing the valve body alone.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
GM changed internal passages when it revised the casting. A valve body from an earlier casting can bolt on but still miss the passage changes, so matching 0955/0945 on 2010-and-up units is part of the actual fix.
It is marked directly on the valve body casting. Pull the pan and check it against 0955/0945 before ordering, or send us your year, model, and VIN and we will confirm.
If the delay traces to bore wear in this casting's line pressure or clutch apply circuits, yes. Persistent delay after a correct install can also point to pump wear, which is a separate part.
This listing is the valve body casting itself. If your solenoids have already failed independently, pair it with a 6L90 solenoid kit.
Fresh filter, pan gasket, and Dexron VI ATF at minimum. If towing has already stressed the clutch packs or planetary, address those at the same time rather than after.
Yes. Run the adaptive shift relearn with a scan tool after the install, since skipping it is a common reason a correctly fitted valve body still shifts rough at first.
