6L80 valve body for 2006-2017, OEM and ready to install. Ships fast from the USA.
If a 2006-2017 Silverado, Tahoe, Suburban, Camaro, Corvette, Sierra or Yukon has a torque converter clutch shudder, a stored code P0741, or no reverse after a clutch failure, GM assigns the factory valve body for that unit the part number 24254908. This is that exact OEM valve body, so instead of tracking down a casting number or hoping a generic listing matches, you are ordering the part GM built for this application.
The 6L80 is GM's 6-speed rear-wheel-drive electronic automatic used across half-ton trucks and SUVs and some performance cars. The valve body carries the shift and pressure control solenoids and routes line pressure through the pressure regulator and clutch regulator valves to apply the 1-2-3-4 clutch, the 3-5-R clutch, the 4-5-6 clutch and the torque converter clutch in the right sequence for each gear. GM built the 6L80 to handle up to roughly 650 lb-ft of engine torque, and the three clutches named above are the ones that actually fail on this transmission when that limit is pushed or the fluid is neglected.
GM's own Preliminary Information PI1413 traces low-speed shudder in V4 mode to a broken torque converter clutch regulator valve spring inside the lower valve body, and PI1393B covers P0741 from damaged torque converter clutch friction material. Our 6L80/6L90 3-5-R clutch failure guide covers the drum cracking failure in detail, including the dot-matrix QR label GM added to updated drums.
Pull codes and check line pressure before ordering. P0741 with normal line pressure points at the TCC regulator valve or converter clutch material rather than the whole valve body, while a no-reverse or bang-into-reverse complaint after high mileage usually means the 3-5-R drum has already failed and needs its own repair, not just a valve body. Our 6L80 common problems and fixes guide runs through all seven failures that actually show up on this transmission so you are not guessing which one you have.
GM used this valve body across 6L80 production from 2006 through 2017, covering Chevrolet Silverado and GMC Sierra, Tahoe, Suburban, Yukon, Camaro and Corvette depending on year and engine. Because it is the factory part number, the fastest way to confirm fitment is to check your old valve body for the same casting marks, or send us your year, vehicle and VIN and we will verify it before it ships. The full range of 6L80 parts we carry is on the 6L80 parts page.
Drop the pan, change the filter, and refill with Dexron VI so debris from the failed part is not pulled into the new valve body. Torque the bolts in sequence to spec and let the transmission control module relearn its shift adapts over the first several drives. If codes or symptoms pointed at end plug leakage before you ordered, a 6L80 valve body end plug kit is worth having on hand, and if the complaint started with no reverse, inspect the 6L80 sprag clutch for related wear at the same time.

This is the OEM valve body carrying GM part number 24254908, built for 6L80 applications from 2006 through 2017, not a generic aftermarket substitute.
If the TCC regulator valve or related hydraulics in the valve body are the cause, yes. If the torque converter's clutch friction material itself is damaged, the converter also needs to be replaced; checking line pressure first helps tell the two apart.
A cracked or welded 3-5-R clutch drum is a common cause of no reverse or a bang into reverse on the 6L80, and that failure is in the clutch pack, not the valve body. Check the drum before assuming the valve body alone will fix it.
Match the casting marks on your original valve body, or send us your year, vehicle and VIN and we will confirm fitment before shipping.
A new filter and fresh Dexron VI fluid at minimum. If your symptoms included leaking end plugs or sprag wear, address those at the same time so the new valve body is not working against a failing part elsewhere in the unit.
