A finned aluminum pan that adds cooling surface and a drain plug to the GM 700R4 and 4L60E, so the fluid runs cooler and the next service is not a full pan drop.
If your Silverado, Tahoe, S10, Camaro or older 700R4 car runs hot when it works and every fluid change turns into a pan full of ATF down your sleeves, this is the pan people search for. It is a finned, plated aluminum replacement for the shallow 2-5/8 inch pan on the GM 700R4, 4L60 and 4L60E, crossing to SP8594BK, and it comes with a gasket, a bolt set and a drain plug. It does not include a filter, so plan on one in the same order.
In a 4L60E the pan is the sump the pump pulls from. The filter hangs from the valve body into the bottom of the pan, so the pan floor sets how much fluid surrounds the pickup and how far the filter sits from anything that could crush it. Every quart that leaves the converter and cooler drains back here before the pump picks it up again, which makes the pan the one large surface where returning fluid can give up some heat before it goes back into the valve body and clutch packs. A stamped pan is thin and smooth; this one adds cast fins along the outside to give the air more metal to pull heat from. Hot fluid is what ages ATF, and once it thins and loses pressure stability the 3-4 clutch pack, the weakest spot in this unit, is the first thing to pay for it.
A pan does not fix slipping that is already happening. If the 4L60E flares on the 2-3 or 3-4 shift, has no 3rd or 4th gear, or the pan comes off full of friction material, the problem is inside the unit and a new pan is a cleanup step, not the repair.
Look underneath and measure the pan you have. A shallow 4L60E pan is about 2-5/8 inches deep; GM put a deeper pan on many 1998 and later full-size C/K trucks and G vans to add capacity, and that deep pan came with a longer dipstick, tube and stop bracket. Find the actual leak point before blaming the pan, since cooler lines and the output seal drip onto it. Our 4L60E filter and pan service guide covers reading the pan debris and how often to service, and the high-mileage checklist covers cooler flow, which matters more than any pan for temperature.
This pan fits the 700R4, 4L60 and 4L60E with the shallow pan: 1993-2013 4L60E trucks and SUVs such as the Silverado and Sierra 1500, Tahoe, Yukon, Suburban, S10, Sonoma and Blazer, plus Camaro and Corvette, and earlier 700R4 cars and trucks. If your truck has the deep pan, this shallow pan only works if you also switch to the short filter and the standard-pan dipstick and tube, otherwise the fluid reading will be wrong. Some trucks with heavy-duty packages and swaps use different pans, so match the pan depth and bolt pattern to what is on the vehicle, or send us your year and VIN before ordering. Every 4L60E part we carry is listed on the 4L60E parts page. If you want to keep the extra capacity of a deep-pan truck, the 4L60E deep aluminum pan kit is the right choice instead.
Drain from the corner of the old pan, drop it, and pull the filter straight down so the seal comes out with it; if the seal stays in the pump bore, hook it out without scoring the bore. Install a new shallow filter and seal. Clean the case rail with a plastic scraper, set the gasket dry, and start every bolt by hand before snugging them in a crossing pattern. GM lists 12 N-m (about 9 lb-ft) for the factory pan bolts; aluminum pans with their own hardware can list a different figure, so use the spec packed with the pan and never crush the gasket chasing a seep. Snug the drain plug with its washer. Refill with Dexron VI, start the engine, move through every range and check the level hot. If you would rather have a filter and pan in one box, the 4L60E pan service kit with filter covers 1998-2013, and if codes or a harsh 1-2 shift came with the leak, the solenoid and filter service kit can go in during the same pan drop.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It bolts to the same case, but it is the shallow 2-5/8 inch pan. GM paired the deep pan with a longer dipstick, tube and stop bracket, so switching to this pan also means a short filter and the standard-pan dipstick setup. If you want to keep the deep pan capacity, choose the deep aluminum pan kit instead.
No. The pan comes with a gasket, bolts and a drain plug. Buy a filter that matches the shallow pan depth, because a deep-pan filter will not fit under a shallow pan.
It helps by adding cooling surface to the sump, but it is not a substitute for a working cooler. Low cooler flow, a clogged cooler after a failure or a slipping converter clutch will still run fluid hot. Check cooler flow and fluid condition first.
Dexron VI ATF. GM made Dexron VI the backward-compatible service fill for its automatics, including the 4L60E, so it is correct for older 700R4 and 4L60E units too. Set the final level hot on the dipstick.
GM lists about 9 lb-ft for the factory pan bolts. Aluminum pans that ship with their own hardware can use a different figure, so follow the spec in the box, tighten in a crossing pattern and do not over-squeeze the gasket.
