Steel replacement pan with filter, filter seal and pan gasket for GM 4L80E and 4L80 trucks, replacing 24204278 and 265-810 in one service.
If the pan under your 4L80E is pushed in from a rock, a careless floor jack or a trail, or it weeps at every corner no matter how many gaskets you throw at it, this kit replaces the whole service package in one box: a stock-depth steel pan, the pickup filter, the filter neck seal and the pan gasket. It is built for the GM 4L80E and 4L80 heavy-duty automatic in Chevrolet and GMC Silverado and Sierra 2500 and 3500, Suburban, Tahoe and Yukon, K3500 and Cadillac applications, including the 1997-2009 trucks that make up most of the 4L80E fleet still working today.
The 4L80E pump draws every drop of oil it sends to the valve body, clutches and converter through one filter that hangs off the case into the pan sump. The pan is more than a cover: its floor depth sets where the filter pickup sits relative to the fluid. When a pan gets dented upward, the floor crowds the filter body, restricts the inlet and can lift the neck partly out of its bore. The pump then pulls air along with oil, line pressure gets unstable, and the clutches that were holding fine start to slip under load. That is why a bent 4L80E pan is a mechanical problem, not a cosmetic one, and why this kit pairs the pan with a filter sized for it.
Look at the pan first. A dent you can see from under the truck, rust scale on an older work truck, or a flange that no longer sits flat is enough reason to replace it. Then check fluid level hot, in Park, on level ground; a low reading can produce the same whine. When the old pan comes down, read what is on the magnet and the pan floor, because black lining material or hard metal means you are documenting a failure, not doing maintenance. Our 4L80E filter and pan service guide covers how to read the pan, and the 4L80E common problems guide helps separate a pickup problem from worn bushings or clutches.
The listing calls out GM pan 24204278 and the 265-810 aftermarket pan, with the filter and seal crossing to GM 24204277, 24208847 and 24210468. It fits the 4L80E and 4L80 in GM heavy-duty trucks and SUVs, including 1997-2009 models. The 4L80E was built in shallow and deep pan versions over its life, and the filter is matched to the pan depth, so this kit is meant to be installed as a set rather than mixed with an old pan or a deep aftermarket pan. Compare the bolt pattern and depth against the pan on your truck, or send us your year and VIN and we will confirm. You can browse every part we carry for this unit on the 4L80E parts page.
If the pan off reveals more than wear, pair this kit with the 4L80E pressure control solenoid or, for a truck heading to the bench, the 4L80E overhaul kit. If you only need the pan and already have a filter, see the 4L80E pan with drain plug.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a stock-depth steel replacement pan, and the filter in the kit is matched to it. If your truck has a deep aftermarket pan, you need a deep-sump filter instead.
Yes. The kit includes the pan, the filter, the filter neck seal and the pan gasket, so the pan job can be done in one trip.
Dexron VI. A pan-drop service takes roughly 7 to 8 quarts; buy two gallons so you have enough for the hot level check.
GM lists 18 lb-ft (24 N-m) for the stock steel pan to case. Tighten criss-cross in two passes, never around the perimeter in one pass.
Recheck that the old filter seal did not stay in the bore, then verify fluid level hot. If shift complaints such as 2nd gear starts persist, the valve body AFL filter and solenoid feed circuit are the next places to look.
