About this product

A 2011-model 6L90 that bangs between gears, hangs on a shift longer than it used to, or trips a pressure-control code after a fluid service is usually telling you the valve body's internal bores have worn, not that the clutches themselves are shot. This listing is a used OEM valve body, reference number 24249178, pulled from a running 2011 6L90, inspected and function-tested before it goes out, and it is a lower-cost alternative to a new or remanufactured unit for an owner who just wants the 2011-specific part back on the road.

Why this is listed for 2011 specifically

GM revised the 6L90 valve body casting and connector layout more than once across the transmission's production run, and a part that bolts up cleanly on an early build can have a different solenoid harness or bore layout than a later one. Buying a part pulled from a confirmed 2011 unit removes the guesswork of matching a generic listing to your casting marks. If your truck or SUV falls outside the 2011 model year, we carry other 6L90 valve body listings built around different year ranges and conditions.

Symptoms this part is pulled to fix

Confirm it's the valve body before you order

Drop the pan and check the fluid condition first. If it's burnt or full of friction material, a clutch pack is failing and a valve body swap by itself will not resolve that complaint. Our shift solenoid symptom and testing guide covers how to isolate a solenoid wiring fault from an internal bore wear issue using the stored codes, and if you're not certain which generation of GM six-speed you're working on, our 4L80E vs 6L90 comparison explains how to tell them apart by pan shape and bolt pattern before you order parts.

Fitment

This unit is pulled specifically for the 2011 model year across the 6L90 platform, used in Chevrolet Silverado 2500/3500 HD, Express, Camaro ZL1, Corvette Z06/ZR1, and GMC Sierra HD and Savana. Reference part number 24249178 against the casting on your own unit before installing, and reach out with your VIN if you want us to confirm the match ahead of time rather than after it arrives.

Install notes

Service the fluid and filter at the same time as the swap so none of the old unit's wear debris ends up circulating through the replacement. Torque the case and TEHCM fasteners to spec in the correct order, and perform the adaptive relearn after reconnecting the battery so the computer isn't still compensating for the old valve body's wear pattern. Because this is a used part, it's worth confirming reverse and the 3-5-R clutch pack are healthy on your own unit; our 3-5-R clutch failure guide covers that failure mode and the codes it triggers so you're not chasing two problems with one part replacement.

6L90 Valve Body 2011: common questions

Is this a new or used part?

It is a used OEM valve body pulled from a running 2011 6L90, inspected and function-tested before it ships. It is a lower-cost option than a new or remanufactured unit.

Does this fit other model years besides 2011?

This specific unit is pulled and listed for the 2011 model year because the 6L90's casting and connector layout changed across its production run. For other years, see our other 6L90 valve body listings.

What is reference number 24249178?

It is the OEM part number stamped on this valve body. Check it against the casting marks on your own unit, or send your VIN and we can confirm the match before you order.

What symptoms point to a worn 6L90 valve body?

A shift that bangs in, a gear held longer than normal before it changes, converter clutch shudder at cruise, and a stored pressure-control or solenoid code with clean fluid are the typical signs.

Does a used part come with any warranty?

Yes, this listing carries a 1-year warranty even though the part is used and function-tested rather than new.

What should I check before assuming the valve body is the problem?

Drop the pan and look at the fluid. Burnt fluid or friction material points to a clutch pack problem that a valve body swap alone will not fix, so rule that out first.
