Cast aluminum 16-bolt deep pan that replaces a rusted, dented or leaking stamped steel pan on GM 4L60E, 4L65E and 4L70E trucks and SUVs.
Salt, gravel and floor jacks are hard on the stamped steel deep pan under a GM truck. If your Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, TrailBlazer or Envoy has a pan that is rusting at the flange, dented on the bottom or seeping at the gasket, this cast aluminum deep pan is the replacement. It is the 16-bolt deep sump design used on the 4L60E, 4L65E and 4L70E, crosses to 265-811 and to GM pan numbers 24209295, 24229658, 24215535 and 24240207, and has a drain plug for future services.
GM did not put the deep pan on these trucks for looks. Sonnax records that in 1998 the 4L60-E on C/K/G trucks and vans received a deeper pan specifically to raise fluid capacity for heavier vehicles, along with a longer dipstick, tube and stop bracket. Novak lists the 4L60-E at 8.4 or 11.4 quarts depending on converter, and up to 14 quarts in deep pan form. That extra volume is thermal mass: more fluid to absorb heat when towing or idling in traffic, and more margin before the pickup starts to draw air on a grade. Keeping the deep pan when you replace it preserves all of that.
Clean the area and find where the leak starts; cooler line fittings and the range switch area drip onto the pan and are often misread as a pan leak. When the pan comes down, check the debris. If you find clutch lining or steel, the transmission has internal wear, and the 4L60E common problems guide explains which failures leave which debris. Harsh or soft shifts with code P0748 point at the pressure control solenoid, not the pan; the 4L60E shift problems guide walks through that diagnosis.
Listed applications: 1999-2013 Silverado 1500 and Sierra 1500, 2000-2008 Tahoe and Yukon, 2000-2009 Suburban 1500, 2002-2009 Avalanche, and 2002-2009 TrailBlazer and Envoy including the 2006-2009 TrailBlazer SS. It does not fit the 4L80E, 6L80E, 6L90E, Powerglide or the Corvette shallow pan unit. On Colorado and Canyon 4WD and the H3 and H3T, the deep casting can contact the front driveshaft, so measure clearance before choosing it for those. Year and model alone are not proof: confirm a 16-bolt deep pan and deep filter on your case, or send us your year and VIN. More service parts are on our 4L60E parts page.
Trucks that tow should look at cooler capacity too; a 6AN braided cooler line kit for 4L60E and 4L65E makes an auxiliary cooler install cleaner. If shift complaints came along with the leak, price a 2003-up master solenoid kit with pressure switch while the pan is off.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is listed for the 16-bolt deep pan used on the 4L60E, 4L65E and 4L70E. Confirm your current pan is the deep style before ordering.
On 4WD Colorado and Canyon and on the H3 and H3T, the deep casting can contact the front driveshaft. Measure clearance before ordering for those trucks.
Use the deep pan filter for your transmission. A standard-depth filter will not sit correctly in this sump.
Yes, so future fluid changes can be a drain-and-fill instead of dropping the pan every time.
Refill with Dexron VI. A pan drop only replaces part of the total fill, so add fluid gradually and check the level hot with the engine running in park.
