Cast aluminum replacement oil pan for GM 4L60E, 4L65E and 4L70E units, replacing OE 24229658 on 1999-2008 Silverado, Tahoe and Yukon.
A 4L60E that leaves a spot on the driveway no matter how many gaskets you put on it usually has a pan problem, not a gasket problem. This listing is the pan alone: a cast aluminum replacement for GM part number 24229658, also listed for 24215535 and 24209295, for the 4L60E, 4L65E and 4L70E in Silverado, Sierra, Tahoe, Yukon, Trailblazer, Envoy, Express, Astro and S10 trucks. It bolts to the standard 4L60E rail and uses the stock-style gasket and filter, so it is the part to buy when the steel pan itself is the thing that has failed.
The pan holds the fluid the pump draws from and gives the filter a fixed position under the valve body. Its flange is also half of the seal: the gasket only works if the pan rail lies flat against the case at every bolt. A stamped steel pan has a thin rail that deforms easily. Overtighten one bolt to chase a seep and the steel dishes in around the hole, which lifts the rail between bolts and opens a new leak path. A cast pan has a thick, rigid rail that clamps the gasket evenly and does not bend around the bolts.
Running a 4L60E low on fluid is how a leak turns into a transmission job. Low level lets the filter pull air, line pressure drops, and the clutches slip and overheat, the same chain that ends with a burned 3-4 pack. A dented floor that crowds the filter can starve the pump the same way and show up as whine and delayed engagement.
Clean the area and find where the fluid actually comes from. The cooler line fittings, the output shaft seal, the shift selector shaft and the speed sensor can all drip onto the pan and fool you. If the wet line starts at the rail, drop the pan and lay a straightedge across the flange. Our 4L60E high-mileage service checklist covers the other leak points and checks worth doing while you are under there, and the filter and pan service guide explains what the debris in the old pan is telling you.
The listed fitment is Silverado 1500 1999-2007 and Silverado Classic 2007, Tahoe 1998-2009, S10 1998-2003, Blazer 1998, Astro 1999-2004, Avalanche 2007-2008, Express 1500/2500 and Trailblazer 2003-2009, Escalade 2002-2006, Yukon 2000-2008, Yukon XL 2004-2008, Sierra 1500 1999-2008, Sierra 2500 2000, Envoy 2002-2009, Sonoma 1998-2004, Safari 1999-2004 and Canyon 2007-2011. GM fitted some 1998 and later trucks and vans with a deeper pan and a longer dipstick to match, so compare your old pan's part number and depth before you order, or send your year, model and VIN. Browse the rest of the lineup on our 4L60E parts page.
If you would rather buy one box, the aluminum pan kit with filter and drain plug includes the service parts. If the pan comes off with heavy friction debris, a 4L60E master rebuild kit with frictions and steels is the realistic next step.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the pan only. Use a new 4L60E pan gasket and filter with it, or choose one of our pan kits that include them.
Check the part number or depth of your current pan and compare against the listed years. Some 1998 and later trucks and vans came with a deeper factory pan, and those need the matching deep pan and dipstick. Send your VIN if you are unsure.
Usually the rail has been bent by overtightened bolts or the pan floor is rusted. A flat, rigid cast rail clamps the gasket evenly, which a distorted steel pan cannot do.
It is made to replace the factory 24229658 pan rather than to add capacity. Either way, set the final level hot with Dexron VI rather than going by a quart count.
It is made to the factory pan footprint for the listed vehicles. On lifted, lowered or swapped trucks, check clearance near the exhaust and crossmember before tightening.
