Complete GM 6L80 service kit: steel oil pan, filter, metal-reinforced gasket, drain plug and bolts to reseal the transmission and change fluid.
If your 2006-up Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche or Escalade has a 6L80 that is weeping at the pan rail, overdue for its first fluid service, or flaring on the 1-2 shift, this kit handles all of it in one trip under the truck. You get a stamped steel oil pan with a threaded drain plug, a new filter, a rubber pan gasket with a metal reinforcement core, and the mounting bolts. It replaces GM pan 24222657 and Dorman 265-582. The big win is the drain plug: the factory 6L80 pan does not have one, so this is the last time you have to drop a full pan of Dexron VI on yourself.
The 6L80 is a six-speed rear-wheel-drive automatic run by a combined valve body and control module bolted inside the case, right above the pan. The pump draws fluid through the filter, which plugs into the case with its own neck seal, and sends it to that valve body, the clutch packs and the converter. Because the controls live inside the sump, clean fluid matters more on this unit than on older designs with an external computer. GM's 2012 Silverado owner manual lists the pan and filter refill at 5.7 liters (6.0 quarts) for the 6L80-E, so a pan drop only exchanges part of the fluid in the system. The pan gasket is the seal everything relies on. The reinforcement core in this one lets it hold even clamp load across the rail without squeezing out, which is where a plain rubber gasket starts to seep on a high-mile truck.
Clean the case and pan, drive to full temperature and put a light on the rail. Wet at the pan means pan or gasket. Wet at the bell housing, output seal or cooler line fittings is a different repair. Then check the level at the check plug in the correct temperature window and scan for codes. A pan service will not fix P0716, P0717 or P0751 valve body and module faults, so rule those out first. Our 6L80 transmission service guide walks through the level check, and the 6L80 high-mileage service checklist covers what else to inspect past 100,000 miles.
This kit is listed for the GM 6L80 and 6L80E, 2006 and up, in the Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche and Escalade. Two cautions. The 6L90 used in heavier trucks takes a longer, deeper pan and a different filter, so this kit is not for it. And some later trucks in this window came with an eight-speed instead. Check the RPO code on the glovebox or door label (MYC is the 6L80) or read the case tag, or send us your year and VIN and we will confirm it. Everything else we carry for this unit is on the 6L80 shop page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 6L90 uses a longer, deeper pan and a different filter. This kit is the shorter 6L80 and 6L80E pan. Check the RPO code (MYC for 6L80, MYD for 6L90) or the case tag before ordering.
GM lists 5.7 liters (6.0 quarts) of Dexron VI for a 6L80-E pan and filter service. Have a little extra on hand and set the final level hot at the check plug.
Yes. GM service information calls for a new filter neck seal every time the filter is removed. Make sure the old one did not stay stuck in the case bore before you push the new filter in.
GM considers the 6L80 pan gasket reusable as long as it is not stuck to the case or pan or damaged. With the drain plug in this pan, many future services will not need the pan off at all.
Sometimes. GM bulletin 20-NA-142 names depleted fluid additives as a cause of 6L80 and 6L90 shudder and surging and starts with a fluid service. If the shudder stays after fresh fluid, the converter or TCC controls need a closer look.
