Cast-aluminum deep sump pan for the Ford 6R140 TorqShift that adds fluid capacity and finned cooling to keep the 6.7L Power Stroke running cool under load.
Owners shopping for this pan usually have a 2011-2019 F-250, F-350, F-450 or F-550 with the 6.7L Power Stroke and the 6R140 TorqShift behind it, and they are watching transmission temperature climb every time a fifth wheel or gooseneck goes on the hitch. This is a deep cast aluminum sump, cross-referenced to number 328052020, with a black outer finish, a machined gasket rail and a radial fin pattern cast into the floor of the pan. It ships with its mounting bolts, washers and a drain plug in a tapped boss.
The pan is the reservoir the 6R140 pump draws from through the sump filter. Every quart in it is a quart that is not in the converter, the clutches or the cooler at that moment, so a bigger sump spreads the same heat load across more MERCON LV. Ford Component Sales rates the 6R140 for 935 lb-ft and a 250 degree F continuous temperature, and on a loaded truck it is the temperature limit you reach first. The extra volume is the point of this part: Sonnax lists 8.2 quarts to refill after a pan drop with the stock pan, while the deep pan makers list far more for their own deep sumps, so the reserve grows by several quarts. The cast walls and internal fins also add metal for heat to move through, and a thick cast rail does not flex the way a thin stamping can.
A pan adds reserve; it does not repair a cooling fault. Before you buy, read TFT on a scan tool rather than the dash gauge, confirm the converter clutch is actually locking on the highway, and check that the 6.7L secondary cooling loop is full and the cooler lines flow. Our 6R140 overheating prevention guide walks through those checks in order. If the pan you drop has metal in it, stop there: a deep pan on a unit that is already shedding metal just holds more contaminated fluid, and the 6R140 slipping guide is the better next step.
This pan is listed for the Ford 6R140 TorqShift in 2011-2019 F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Power Stroke. The 6R140 was also used behind gas engines and in E-Series and chassis cab builds, but this listing names the 6.7L diesel pickups only, so if your truck is a gas or cutaway application, send us the year and VIN before ordering. A deep pan also hangs lower than stock; on a lifted truck that is rarely an issue, but check crossmember and exhaust clearance on cab-and-chassis builds. The rest of our 6R140 parts are on the 6R140 transmission page.
This kit is the pan, hardware and drain plug only, so order a filter and gasket with it. Our 6R140 filter kit covers the Motorcraft-style BC3Z-7A098-B filter used on 2011-2019 Super Duty units. Drain the old fluid, drop the factory pan, and clean the case rail flat and dry. When the old filter comes out it should have some resistance at the pump intake; Sonnax documented a 6R140 intermittent neutral on grades caused by a filter neck seal with no grip, so seat the new filter fully. Our 6R140 filter and pan service guide lists the 19 pan bolts at 80 lb-in in a crisscross pattern and the 3 filter bolts at 97 lb-in; use an inch-pound torque wrench, not an impact. Fill with MERCON LV only through the dipstick tube and plan on extra fluid for the deeper sump; the 6R140 service kit with 10 quarts of MERCON LV is a good starting point, with a few more quarts on hand. Set the final level hot, with TFT between 196 and 216 degrees F, and recheck after the first drive.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, it is listed for the 6R140 in 2011-2019 F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Power Stroke. If your truck has a gas engine or is a cutaway or chassis cab, send us the year and VIN before ordering.
No. The listing includes the pan, mounting bolts with washers and the drain plug. Order a 6R140 filter and pan gasket with it so the service is done in one job.
A stock pan service takes about 8.2 quarts of MERCON LV. A deep pan holds several quarts more, so have extra fluid on hand and set the final level hot on the dipstick with TFT between 196 and 216 degrees F.
MERCON LV only. Ford lists MERCON LV for the 6R140 in every application. Do not use the MERCON ULV specified for the later 10R100 and 10R140.
It adds fluid reserve and cooling surface, which helps under tow, but it will not fix a converter clutch that is not locking, a low secondary cooling loop or a restricted cooler. Diagnose those first.
