6L80 Aluminum Transmission Oil Pan Kit with Filter

If your Silverado, Sierra, Tahoe or Yukon has a 6L80 that drips from the pan corners, or you are tired of dropping a full pan of fluid on yourself every service, this kit replaces the factory stamped-steel pan with a cast aluminum one. It includes the pan, a new transmission filter, the pan gasket and a threaded magnetic drain plug, and it covers GM numbers 24222657, 24236933, 29535617 and 24224781 plus the 265-582 replacement pan. It fits the 6L80 behind the 5.3L and 6.2L in GM trucks and SUVs, Camaro, Corvette, Escalade and Hummer H2.

What the pan and filter do in a 6L80

The 6L80 pan is the fluid reservoir for the pump. The filter sits in a bore in the case above the valve body and the pump pulls every drop of fluid through it, so a restricted filter starves the pump and the valve body of pressure. The stock pan has no drain plug and its thin steel flange can distort after repeated heat cycles and removals. Once the rail is not flat, the gasket weeps and the leak can be mistaken for a rear main seal. A cast aluminum pan keeps its sealing rail flat under bolt load, and the drain plug lets you drain and inspect fluid without breaking the seal.

Symptoms this kit addresses

• Fluid weeping from the pan flange or corners after the pan has been off before
• A dented or bent pan from off-road use or a jack placed in the wrong spot
• Pump whine, delayed engagement or overheating from a restricted filter
• Shudder or surging tied to worn-out fluid, which GM addresses with a fluid service

How to confirm before buying

Clean the transmission and drive the truck, then look for fresh fluid at the pan rail versus the cooler lines, output seal or bell housing. If the pan is the leak, this kit fixes it. If the complaint is shifting rather than leaking, read codes first: P0716, P0717 and P0751 point to the TEHCM and valve body, not the filter. Our 6L80 transmission service guide covers the fluid check procedure, and the high-mileage service checklist explains what to look for on the magnet.

Fitment

Listed vehicles are the Silverado 1500 2009-2019, Sierra 1500 2007-2019, Tahoe 2009-2019, Yukon and Yukon XL 2007-2019, Suburban 2009-2019, Avalanche 2009-2013, Camaro 2010-2015, Corvette 2006-2014, Escalade 2007-2015 and Hummer H2 2008-2009. All use the 6L80 (RPO MYC). Check clearance around the pan for exhaust and crossmember on lifted or modified trucks, and compare the bolt pattern to your old pan before you start. Send the year and VIN if you want us to confirm. See all 6L80 parts on our 6L80 collection page.

Install notes

• Support the transmission, remove the old pan and let it drain, then scrape the case rail to bare metal. Leftover gasket on the case is the common cause of a new leak.
• Pull the old filter straight down out of the case bore. GM requires the filter seal in the bore to be replaced every time the filter comes out, so make sure the old seal is removed and the new one sits square.
• Start every bolt by hand, then tighten in a crossing pattern to the GM spec. Overtightening dishes a flange or pulls a case thread.
• Refill with Dexron VI. A pan and filter service on the 6L80 takes about 6 quarts. Set the level at the check plug with the engine running at operating temperature on level ground.
• Read the drain plug magnet at each service. Fine gray paste is normal; clutch material or steel chunks mean internal wear, and a 6L80E master rebuild kit may be next.
• If the truck runs hot towing, a new cooler such as the 6L80 cooler for 2014-2018 protects the fresh fluid.

Does this 6L80 pan have a drain plug?

Yes. It has a threaded magnetic drain plug, which the factory steel pan lacks, so you can drain fluid without removing the pan.

Which part numbers does this pan replace?

The listing covers GM 24222657, 24236933, 29535617 and 24224781 as well as the 265-582 replacement pan.

Is the filter seal included?

The kit includes the pan, filter, pan gasket and drain plug. GM says the case-bore filter seal must be replaced whenever the filter is removed, so check that a seal comes with the filter or order GM seal 24225347.

How much fluid does the 6L80 take for a pan service?

GM lists about 5.7 L (6.0 qt) of Dexron VI for a 6L80 pan and filter change. Top off at the check plug with the transmission at operating temperature.

Can I reuse the new gasket at the next service?

GM considers the 6L80 pan gasket reusable unless it is stuck to the case or pan. Inspect it each time and replace it if it is torn or deformed.
