Replaces the internal filter and molded oil pan gasket on GM 10-speed 10L60, 10L80 and 10L90 transmissions when you drop the pan for a fluid service.
If your Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, Escalade or Camaro is due for a transmission service, or the pan on its GM ten-speed is seeping, this is the kit the job is built around. It contains the internal filter and a molded oil pan gasket for the 10L60, 10L80 and 10L90, and it cross-references GM part number 24294355 and filter number TF937. The pan comes off wet on these trucks, so the filter and gasket should always be replaced together rather than reusing a gasket that looked fine.
The ten-speed filter is not a flat screen. Mike Souza's teardown for Transmission Digest found two media in one housing: a coarse orange section and a fine white section about twice its size. On a cold start the thick fluid takes the easy path through the coarse media so the pump primes quickly. As the fluid warms and thins, more of the flow moves through the fine media, which is where small wear particles get caught. That design means a loaded filter restricts the pump inlet hardest when the fluid is hot and the pump needs the most volume. Everything downstream depends on clean supply: the pump, the regulator valves and the solenoids that sit directly in the valve body casting. Debris that gets past a tired filter ends up in those bores, which is exactly where the 10L80's known valve body problems start.
Most of the time this is a scheduled maintenance part, not a repair, but the pan tells you a lot once it is down. Fine gray paste on the magnet is normal wear; bright metal flakes or heavy black friction material mean a fluid and filter change will not fix the problem. GM TechLink notes that pump aeration after a service can come from low fluid or a filter seal left behind in the bore, so pull the old filter and confirm its seal came out with it. Our 10L80 filter and pan service guide covers how to read the pan and the full fill procedure, and the pump failure symptoms guide helps separate a starved pump from a failing one.
Per the listing, the kit covers 2019-2024 Silverado 1500 and Sierra 1500, 2021-2024 Tahoe, Suburban, Yukon, Yukon XL and Escalade, 2020-2024 Camaro, and the Cadillac CT4, CT5 and CT6 with the GM ten-speed. GM uses the 10L80 under several RPO codes, so if you are unsure which unit you have, read the RPO label on the driver's door pillar or send us your year and VIN. It is not for the Ford 10R80, which uses a different filter and pan. More parts for this family are on our 10L80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It matches GM part number 24294355 and filter reference TF937. It includes one internal filter and one molded oil pan gasket.
Yes. The listing covers the 10L60, 10L80 and 10L90 GM ten-speeds. It does not fit the Ford 10R80.
No. The molded gasket seats dry. Clean both sealing surfaces, install it without sealer and tighten the pan bolts evenly in a cross pattern.
GM lists 7.7 liters, or 8.1 quarts, of Dexron ULV for a pan and filter service on the 10L80. Buy a couple of extra quarts so you can set the level properly when hot.
The most common causes are a low fluid level or the old filter seal left in the pump inlet bore, which lets the pump pull air. Recheck the level hot at the check plug and confirm the seal situation.
