10L80 Valve Body, remanufactured and ready to install. Fits the 10L80. Ships fast from the USA.
If your 2017-up Silverado, Sierra, Tahoe, Suburban, Yukon or Escalade is shifting harsh, slipping between gears, flaring on the 1-2 shift, or has gone into limp mode with a pressure or solenoid code, the 10L80 valve body is the most common point of failure on this 10-speed - and on the truck and SUV side of this platform, GM has twice issued safety recalls for exactly this failure mode. This is a remanufactured, bench-ready valve body built for the 10L80, so you install a known-good unit instead of diagnosing bore wear and solenoid drift piece by piece.
The 10L80 is a 10-speed, clutch-to-clutch automatic with no mechanical fail-safe, so every shift depends on the valve body routing line pressure through precision bores and spool valves to the correct clutch, timed by the shift and pressure-control solenoids it carries. GM's own recall filings describe a worn transmission control valve causing a gradual loss of valve pressure that produces harsh shifting, a Service Engine Soon light, reduced engine performance, and in the worst cases a momentary rear-wheel lock-up during deceleration - not a slow fade you can ignore.
NHTSA recall 26V085 covers 43,743 2022 Tahoe, Suburban, Yukon, Yukon XL, Escalade and Escalade ESV units with ETRS for this exact control-valve failure, and the earlier N252536751 coverage describes the same gradual pressure loss on the broader 10-speed truck and SUV population - so if your symptom matches, you are not chasing something unusual. Scan for codes and note which shifts are affected before ordering; our 10L80 valve body symptoms and testing guide walks through isolating a hydraulic valve body fault from a solenoid-only problem, and our recall writeup covers which VINs and model years GM has already covered under warranty.
This listing is built for the 10L80 as installed across the 2017-up Chevrolet Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon and Cadillac Escalade. The 10L80 ran through multiple casting and solenoid revisions over this span - Sonnax documents a Gen. 3 service valve body released in mid-2025 with relocated solenoids - so match your connector count and casting marks against the photos, or send your VIN so we can confirm the exact revision before you order. The full 10L80/10L90 parts collection has everything else we stock for this transmission.
Drop the pan and filter at the same time as the valve body swap so debris from the old unit does not circulate into the new one, torque the valve body bolts in sequence to spec rather than corner to corner, and refill with DEXRON ULV only - GM's capacity for this family is 7.7 L / 8.1 qt. Pair the swap with a fresh filter and pan gasket kit so you are not running new valving on old, contaminated fluid. Clear codes and run the TCM's adaptive relearn after the swap so the computer re-times clutch fill against the new unit rather than the worn one. Check your recall status with your dealer before paying for this part, and if your original complaint was a stored solenoid code rather than a mechanical shift problem, a 10L80 solenoid kit paired with fresh fluid may be the cheaper fix.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Possibly - NHTSA recall 26V085 covers 43,743 2022 Tahoe, Suburban, Yukon, Yukon XL, Escalade and Escalade ESV units for this exact failure, and an earlier campaign covers additional model years. Check your VIN with your GM dealer before buying if your truck or SUV falls in that range.
Harsh or flared shifts (especially 1-2), slipping between gears, a sudden downshift to 2nd or momentary wheel lock-up on deceleration, and limp mode with a stored pressure or solenoid code.
It fits the 10L80 as used in the 2017-up Silverado, Sierra, Tahoe, Suburban, Yukon and Escalade, but GM has run multiple casting and solenoid revisions over that span, so match your connector count and casting marks against the photos or send your VIN to confirm.
DEXRON ULV ATF, filled to GM's published capacity of 7.7 L / 8.1 qt.
Yes - clear codes and run the TCM's adaptive relearn so the computer re-times clutch fill against the new valve body.
Not necessarily - a 10L80 solenoid kit paired with fresh fluid and filter can fix a solenoid-only fault for less than replacing the whole unit.
