6L80 Pressure Control Solenoid 2009, new and ready to install. Fits the 6L80. Ships fast from the USA.
Read this first: despite the listing name, this item is not a loose pressure control solenoid. On the 6L80 the pressure control solenoid is built into the control module and is not sold separately. What this listing actually ships is a genuine ACDelco 6L80 transmission service kit for 2009-up Chevrolet and GMC trucks and SUVs: an ACDelco internal transmission filter, an ACDelco pan gasket and seven quarts of ACDelco Dexron VI fluid. If you are chasing a pressure complaint on a Silverado, Sierra, Tahoe, Suburban or Yukon, a correct filter and fluid service is the first step anyway, and this kit gives you the factory parts to do it in one order.
The 6L80 is a clutch-to-clutch six-speed, so every shift depends on clean, correct fluid reaching small regulator valves and solenoid passages. The pump draws through the internal filter in the pan and feeds the pressure regulator in the pump cover. The pressure control solenoid in the control module only sets the target; the regulator valve does the work. Varnish, clutch material and broken-down fluid make those valves stick and wear their bores, and that is when line pressure starts wandering. Dexron VI is the fluid GM specifies for the whole 6L family.
If the truck already sets pressure control or clutch performance codes, a service alone may not fix it. Check the fluid level hot through the check plug, then look at what comes out of the pan. Fine gray paste on the magnet is normal wear; flakes of friction material or metal chips point to clutch or pump damage. Our 6L80 P0842 pressure sensor guide explains how the pressure switches in the module report problems, and the 6L80 common problems guide covers shudder, clutch wear and valve body leaks.
The kit is listed for 2009-up Chevrolet and GMC trucks and SUVs with the 6L80. GM has revised the 6L80 filter and seal part numbers over the years, as covered in bulletin 23-NA-224, so check the filter in your pan or send us your year and VIN before ordering and we will confirm it matches. It is not listed for Camaro or Corvette. Everything else for this unit is on our 6L80 parts page.

No. Despite the listing name, this is an ACDelco 6L80 service kit with an internal filter, pan gasket and seven quarts of Dexron VI. The 6L80 pressure control solenoid is part of the control module and is not sold on its own.
It is listed for 2009-up Chevrolet and GMC trucks and SUVs with the 6L80. GM revised the filter and seal part numbers over time, so send your year and VIN if you want us to confirm before it ships.
GM specifies Dexron VI for the 6L80, which is what this kit includes. Do not mix in multi-vehicle fluids.
Run the engine with the fluid at operating temperature, remove the check plug on the case and let excess drain until it drips. If nothing comes out, add fluid until it does. Follow the exact temperature window in your service information.
It helps when the cause is old or low fluid. If the pan shows friction material or metal, or pressure codes persist after the service, the valve body, clutches or control module need diagnosis.
