Finned cast aluminum deep pan for GM 4L60E, 4L65E and 4L70E trucks that adds about 3 quarts of fluid, with filter, gasket and pan bolts in the box.
If your Silverado, Sierra, Tahoe, Yukon, Suburban, Express, Savana, Trailblazer or S10 runs its transmission temperature up every time you tow, sit in traffic or climb a long grade, or the stamped steel pan is dented and rusting at the drain area, this is the pan kit to look at. It is a deep, finned cast aluminum pan in red for the GM 4L60E, 4L65E, 4L70E and 4L75E, and the box includes a matching filter, a pan gasket, a full set of pan bolts and the hex key to drive them. It is listed against GM pan numbers 24229658, 24240207, 8667545 and 24208576.
The 4L60E has no separate reservoir. Everything the pump feeds to the valve body, torque converter, cooler and lube circuits is drawn up through the filter from the oil sitting in the pan, so the pan sets how much fluid is in the system and how fast it can shed heat between trips through the cooler. This casting is deeper than a stock pan and adds about 3 quarts of capacity. More fluid means each quart spends longer out of the hot path, and the cast fins on the bottom add surface area that a smooth steel pan does not have. A rigid casting also does not flex at the rail the way a thin stamped pan does, which is a common reason an old pan weeps after a few gasket changes.
GM itself made this move in 1998, when C/K and G series trucks and vans started getting a deeper factory pan to carry more fluid in heavy vehicles. Sonnax notes those trucks also got a longer dipstick, tube and stop bracket to match, which matters when you change pan depth (see Install notes).
Heat is what takes out most 4L60E units. Cooked fluid is behind the burned 3-4 clutch pack that leaves a truck with no third or fourth gear, and it speeds up the valve body bore wear that leads to converter clutch slip and P0741. More capacity buys margin; it does not repair a unit that is already slipping.
Read the old pan before you buy anything else. A thin gray paste on the magnet is normal. Chunks of friction material, brass flakes or bright steel mean there is internal damage that a pan will not fix. Our 4L60E filter and pan service guide explains what the debris is telling you, and 4L60E overheating prevention covers coolers, fluid and driving habits if heat is the real problem. If you are hearing a whine, check our noise diagnosis guide first, since a whine can also come from the pump or converter.
This pan fits the 4L60E, 4L65E, 4L70E and 4L75E in 1999-2014 Silverado and Sierra 1500, Tahoe, Suburban, Yukon and Yukon XL, 1998-2014 Express and Savana 1500/2500, 1998-2013 Escalade, 2007-2009 H2, 2002-2009 Trailblazer, 1998-2004 Astro, Safari, S10 and Sonoma, and 1994-2000 C/K 1500 and 2500 trucks. These units share the common 16-bolt 4L60E pan pattern, but check your bolt count and pan shape against the one on your truck before ordering. Vehicles with a tight crossmember, exhaust crossover or skid plate under the pan should be measured for clearance, because this pan hangs lower than stock.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
About 3 quarts more than a standard pan. Fill to the hot-check level on the dipstick rather than using the factory capacity figure.
Use the filter included in the kit. It is matched to this pan depth. A stock filter can sit too high or too low in a deeper pan and pull air or restrict flow.
Not always. GM paired its own deep pan with a longer dipstick, tube and stop bracket, and Sonnax documents that mismatched or missing dipstick parts can make a low unit read full. Make sure the stop bracket is in place and confirm the level after the first heat cycle.
No. This pan is for the 4L60E family only: 4L60E, 4L65E, 4L70E and 4L75E. The 4L80E uses a different pan shape and bolt pattern.
No. A deeper pan helps a healthy transmission run cooler. If the truck is already slipping or the magnet is covered in friction material, the unit needs repair first.
Dexron VI ATF, which is what GM calls for in the 4L60E family.
