Cast aluminum 265-811 style pan for GM 4L60E, 4L65E and 4L70E trucks and SUVs, with a magnetic drain plug and gasket so fluid services skip the pan drop.
Every GM truck owner who has serviced a 4L60E knows the routine: no drain plug, so you loosen the pan bolts, tilt the stamped steel pan and catch most of the ATF on your arms. This cast aluminum pan replaces that factory pan on 1998-2011 4L60E, 4L65E and 4L70E applications, from the Silverado, Sierra, Tahoe, Yukon and Suburban to the Express, Savana, Trailblazer, Envoy, Astro, Colorado, Canyon, Escalade and Hummer H2. It follows the 265-811 pattern and cross-references GM 24229658, 24240207, 24215535 and 24209295, and the box includes a magnetic drain plug and a pan gasket.
On this transmission the pan is more than a lid. It is the sump the filter pickup draws from, so its depth and shape decide how much fluid the unit holds and whether the pickup stays covered on hills and hard stops. Sonnax notes that GM moved the C/K/G trucks and vans to a deeper 4L60-E pan in 1998 to add capacity, and changed the dipstick, tube and stop bracket with it. That is why fitment on this pan starts at 1998 and why the pan has to match the filter you run. Novak lists the 4L60-E at 8.4 or 11.4 quarts depending on converter size, and up to 14 quarts with a deep pan.
Drop the old pan and look at it before you blame it. Fine gray paste on the magnet is normal wear; brass flakes, clutch material or steel chunks mean something inside is failing and a new pan will not fix it. Burned 3-4 clutches and a stripped sun shell are the classic 4L60E failures that show up first in the pan, and our 4L60E common problems guide walks through what each kind of debris points to. If the transmission still shifts well and the debris is light, a pan, filter and fresh fluid is a reasonable service.
Listed fitment is 1998-2011 GM 4L60E, 4L65E and 4L70E trucks and SUVs, using the 265-811 and GM part numbers above. Because GM ran standard and deep pans in this family, measure your current pan depth and confirm the bolt pattern, and make sure the filter you install matches this pan's depth. If you are unsure, send us your year and VIN, or see all 4L60E parts for related service items.
For an Astro or Safari, GM's owner manual lists about 5 quarts for a pan drain and refill, and our Astro van 4L60E guide covers that platform. If the magnet shows heavy clutch material, plan on a high energy friction clutch pack, and on 2003-2008 units with shift complaints, a replacement 4L60E valve body is worth pricing alongside the pan.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The kit includes the aluminum pan, a magnetic drain plug and a pan gasket. Buy a filter that matches this pan's depth and install it at the same time.
Yes, it is listed for the 4L60E, 4L65E and 4L70E in 1998-2011 GM trucks and SUVs, and cross-references GM 24229658, 24240207, 24215535 and 24209295. Compare depth and bolt pattern with your old pan before installing.
Yes. With the drain plug you can do a drain-and-fill between filter services. A drain only removes the fluid in the pan, so repeat it a few times to refresh most of the fluid.
Use Dexron VI ATF and check the level hot with the engine running in park. Add a little at a time so you do not overfill.
A light gray paste is normal. Brass, clutch lining or steel chips point to internal wear such as burned 3-4 clutches or sun shell damage, which needs repair beyond a pan swap.
Normally no. Install the supplied gasket on a clean, dry flange and torque the bolts evenly in a crisscross pattern so the aluminum flange stays flat.
