6L80 Valve Body 2007-00, remanufactured and ready to install. Fits the 6L80. Ships fast from the USA.
If you drive a 6L80-equipped Silverado, Sierra, Tahoe, Suburban, Yukon or Escalade with harsh downshifts, a flare between gears, or a shift that is slow to engage, and you have already priced out the higher-end 6L80 valve bodies, this listing is our value-tier option for the same job. It carries the listing designation 2007-00, is remanufactured and bench-tested before it ships, and comes in well under the price of our full TEHCM-equipped assemblies for buyers whose existing control module is still good and only need the hydraulic valve body replaced.
Every shift in a 6L80 happens because the valve body directs pump pressure through a set of precision bores and spool valves to apply the correct clutch pack or band at the correct instant, timed by the shift and pressure solenoids the TEHCM commands. When the bores or the spool valves inside the valve body wear, pressure leaks past where it should be sealed, and the transmission starts applying clutches late, soft, or out of sequence even though the clutches themselves are still good. Replacing a worn valve body with a corrected, remanufactured unit restores that timing without touching the rest of the transmission.
GM TechLink's bulletin on thermal bypass valve installation documents related hydraulic complaints tied to temperature and pressure control on 6L80/6L90 units in this production era, and the ATRA/GEARS Magazine writeup on clutch failure in the GM 6L80/90 confirms that the 1-2-3-4, 3-5-R and 4-5-6 clutch packs are usually fine mechanically when the real cause is upstream in the hydraulic circuit.
Scan for codes before ordering. A stored pressure control or shift solenoid code paired with a harsh or flared shift is the strongest sign the valve body is the actual cause rather than a worn clutch pack. Walk through our 6L80 Valve Body Problems: Symptoms, How to Test, and Replacement guide for the specific line pressure and solenoid checks, and if your symptoms include a code pointing at a specific shift solenoid circuit, our 6L80 Shift Solenoid Symptoms and Replacement guide explains what inside the valve body actually fails versus what only looks like a solenoid problem from the scan tool.
This unit is listed under the 2007-00 designation for the 6L80. The 6L80 went through multiple casting and connector revisions across its production run, so before ordering, match the casting markings and connector pattern on the valve body currently in your transmission, or send us your year, make, model and VIN so we can confirm this designation is the correct match for your build rather than a nearby but different revision. The full 6L80 parts collection has our other valve body listings if this specific designation does not match your casting numbers.
Drop the pan and replace the fluid and filter at the same time as the valve body. Running the old, contaminated Dexron VI ATF through a freshly remanufactured valve body is one of the fastest ways to put it right back into the same worn condition. Torque the valve body retaining bolts in the correct sequence rather than evenly snugging them, and run the adaptive relearn procedure afterward so the TEHCM's learned shift pressures match the new valve body instead of the one it replaced. For the fluid and filter side of the job, our 6L80E Transmission Rebuild Kit with Filter covers it in one order, and if you are seeing clutch wear alongside the hydraulic symptoms, our 6L80 Clutch Module is a common companion part at this stage.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This is a standalone valve body without a TEHCM control module attached, which is why it costs less than our combined valve-body-and-TEHCM assemblies. If your original control module tests good, this is the lower-cost option since you are only replacing the hydraulic half of the unit.
It identifies this specific listing's casting and revision match within our catalog. Match it against the casting markings and connector pattern on your original valve body, or send us your VIN, since the 6L80 had multiple revisions and the designation is how we track which one this unit is.
Not necessarily. If your existing TEHCM passes a scan tool check and isn't throwing module-specific fault codes, you can reuse it with this valve body. If the module itself is failing, you need a combined assembly instead.
Harsh, flared or delayed shifts paired with a stored pressure control or shift solenoid code point at the valve body. Torque converter shudder without shift timing complaints is more often the pump, which is a different part.
Yes, it carries a 1-year warranty as a remanufactured, bench-tested part.
Use Dexron VI ATF, change the fluid and filter at the same time you install the valve body, torque the bolts to GM's sequence and spec, and run the adaptive relearn procedure afterward so the shift timing is learned fresh rather than carried over from the worn unit.
