10R140 Deep Transmission Pan Cast Aluminum Ford Super Duty

If you tow with a 2020-2026 F-250, F-350, F-450 or F-550 Super Duty and watch the transmission temperature climb on every long grade, this cast aluminum deep sump pan is built for your 10R140. It bolts on in place of the factory stamped pan behind the 6.7L Power Stroke, adds fluid reserve, and puts cast cooling fins into the airstream under the truck. It is also the pan to reach for when the factory pan has been dented on a trail or a rock and is weeping at the rail.

What the transmission pan does in a 10R140

The 10R140 is Ford's heavy-duty ten-speed, and nearly everything it does depends on clean, cool MERCON ULV. The pan is the sump the filter draws from: the pump pulls fluid through the filter sitting in the pan, sends it through the valve body to the solenoids and clutch packs, and the fluid drains back down to be picked up again. Ford's catalog lists one factory pan, PC3Z-7A194-A (superseding LC3Z-7A194-B and -C), across the 6.2L, 6.7L diesel, 6.8L and 7.3L Super Duty trucks, and it is a thin steel stamping with a modest reserve.

A deep cast pan changes two things. More fluid in the sump means the total volume takes longer to heat up, and the filter pickup stays submerged when fluid sloshes to one end on a steep climb or a hard stop with a loaded trailer. The cast fins add surface area so the pan sheds heat instead of storing it. Lower, steadier fluid temperature is what protects ULV fluid from shearing down and keeps the ten-speed's tight solenoid control consistent.

Symptoms that point to a pan upgrade or replacement

• Transmission fluid temperature running high when towing, plowing or hauling at highway speed
• Fluid that comes out dark or smells burnt well before the service interval
• A dented, scraped or bent factory pan, or a leak at the pan rail after an impact
• Harsh or erratic shifts that appear only once the truck is hot and heavily loaded
• A momentary flare or loss of drive on a steep grade, which can mean the pickup is drawing air from a low or sloshing sump

Heat is the 10R140's enemy. The known complaints on this unit, such as erratic shifts that need an adaptive relearn and valve body and solenoid faults, all get worse when the fluid is cooked. A pan will not fix a failed solenoid or a worn converter clutch, but it can help keep a healthy unit from getting there.

How to confirm what your truck needs before buying

Start with a scan tool and watch transmission fluid temperature on a typical tow. If it climbs steadily under a load you pull often, more capacity and fin area is a sound upgrade. If you already have shift codes, solenoid codes or a slipping complaint, diagnose those first; a pan swap is a service, not a repair for an internal fault. Once the old pan is down, read its magnet and look at the filter: fine gray paste is normal wear, while flakes or chunks of friction material mean the unit needs more than a pan. Our filter and pan service walkthrough is written for the 10R80, but reading the magnet and filter works the same way on the 10R140.

Fitment

This pan is listed for 2020-2026 Ford F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Power Stroke and the 10R140 ten-speed, and it interchanges with deep-pan part numbers 328053320 and 328053520. It does not fit the 10R80 used in the F-150, Expedition and Mustang, and it does not fit the 6R140 six-speed in 2011-2019 Super Duty trucks. Ford uses the same factory pan number on the gas 6.8L and 7.3L 10R140 trucks, but this deep pan is listed for the diesel, so gas-truck owners should check underbody and exhaust clearance or send us the year and VIN before ordering. The deeper sump also hangs lower than stock, which matters on a lifted truck that sees rocks.

Install notes

• Drain the fluid, remove the factory pan, and replace the filter while it is open. A 10R140 filter and pan gasket kit or the DF-440 filter kit for the 6.7L covers the filter.
• Clean the case rail completely so no old gasket or sealer is left, and seal the pan the way its instructions specify.
• Torque the pan bolts in a criss-cross pattern to the specification supplied with the pan. Aluminum threads strip easily, so do not lean on them.
• Refill with MERCON ULV only, and expect it to take more fluid than a stock pan service.
• Set the level using Ford's procedure at the specified fluid temperature with the engine running. A deep pan makes a cold level check even more misleading.
• Use the magnetic drain plug at each later service to check debris and change fluid without dropping the pan again.

For fluid background, see our ten-speed fluid type and capacity guide, and if the unit is coming apart for more than a pan, the 10R140 seal ring expander and resizer kit handles the Teflon sealing rings.

Will this pan fit my 2019 F-250 Super Duty?

No. 2019 and earlier Super Duty trucks use the 6R140 six-speed, which has a different pan. This pan is for the 10R140 ten-speed used from 2020 on.

How much extra fluid does a deep pan add?

It holds more than the stock stamped pan, so buy extra MERCON ULV beyond a normal pan service. Fill, then set the final level with Ford's hot check procedure rather than counting quarts.

Do I need a new filter when I install it?

Yes. With the pan off the filter is right there, and a new 10R140 filter is cheap insurance. Clean the case rail before setting the new pan.

Does it fit the 7.3L gas Super Duty?

Ford uses the same factory pan on the gas and diesel 10R140, but this deep pan is listed for the 6.7L diesel. Check exhaust and crossmember clearance on a gas truck, or send us your year and VIN to confirm first.

Will a deep pan lower my transmission temperature?

It adds fluid volume and cooling fin area, which helps the fluid absorb and shed heat under sustained towing. It does not replace a healthy cooler and clean lines, and it will not fix an internal fault that is generating heat.
