10R80 Heavy-Duty Cast Aluminum Transmission Pan 328053110

If the stamped pan under your Ford ten-speed is creased from a rock, weeping at the gasket line, or just took a hit you do not trust, this is a cast aluminum replacement for pan number 328053110 on the 10R80. The listed fitment is 2017-2024 F-150, Ranger, Bronco, Expedition, Explorer and Mustang, plus the 2018-2024 Lincoln Navigator. It is not for the F-150 3.5L PowerBoost hybrid, which uses a different case. The pan weighs about 5 pounds and swaps on in place of the factory part.

What the pan does on a 10R80

On the 10R80 the pan is more than a cover. It is the sump the pump draws from through the filter, and its flange has to stay flat for the gasket to seal against the aluminum case. The factory pan is thin stamped steel, so a ledge, a rut or a jack placed in the wrong spot can push the floor up toward the filter or bow the flange enough to start a slow leak. Ten-speed fluid level is set tight, and losing even a little over time matters: Sonnax notes this family is sensitive to level in both directions, with as little as one quart of overfill causing heat and venting. A cast body resists denting, will not rust, and carries a bit more heat away from the fluid than stamped steel on trucks that tow or idle in traffic.

Signs it is time to replace the pan

• Dents or a pushed-in floor after an off-road or road-debris strike
• A pan gasket that keeps seeping after it has been replaced, usually from a bent flange
• Rust or flaking on an older pan in a salt-belt state
• Fluid level falling between services with drips at the pan rail rather than at the cooler lines
• You are already dropping the pan for a filter change and want a stronger part going back on

How to confirm the leak is the pan

Clean the underside, drive a day, and look for where the fluid starts. Wetness that begins at the pan rail points here; wetness higher up at the case connector, cooler line fittings or the rear seal does not, and a new pan will not cure it. While the pan is off, read what is in it. Ford's harsh-shift bulletins for this unit use gray silt sitting on the filter as a sign of internal clutch damage, so a pan drop is a cheap look inside before something bigger fails. Our 10R80 common problems guide explains what that debris means, and the F-150 10R80 problems guide covers the truck-specific complaints that often get blamed on a leak.

Fitment

This pan is listed as a direct replacement for 328053110 on 2017-2024 F-150, Ranger, Bronco, Expedition, Explorer and Mustang and 2018-2024 Navigator. The Bronco is built with the 10R60, the lighter-duty sister unit, so on a Bronco or any application where you are unsure, pull the number from the old pan and check the transmission tag before ordering. The PowerBoost hybrid is excluded. Pans for this family have been made in more than one version, so if your number does not match, send us your year and VIN and we will check it for you. Everything else we stock for this unit is on the 10R80 parts page.

Install notes

• Raise and support the vehicle level, drain what you can, then loosen the bolts and lower one end of the pan slowly so the remaining fluid and the filter do not dump on you.
• Clean the case sealing surface with a plastic scraper; metal tools gouge the aluminum and create the next leak.
• A gasket and filter are not listed as included, so have them ready. This is the right time to change the filter.
• Start every bolt by hand and tighten in a crisscross pattern to the Ford torque value; uneven clamping bows the flange.
• Refill with MERCON ULV only and set the level through the fill plug at the 206-215 F check temperature, not by counting quarts. A locking 10R80 dipstick makes later level checks simpler on trucks that have the tube.

If the truck also shifts hard or flares once the fluid is right, the pan was not the whole story. A sticking line pressure solenoid is a common cause; see the 10R80 pressure control solenoid.

Does this pan fit the F-150 PowerBoost hybrid?

No. The PowerBoost uses a different transmission case and is specifically excluded from this pan's fitment.

Which pan number does it replace?

It is listed as a direct replacement for pan 328053110 on the 10R80. Compare the number on your old pan and the transmission tag before ordering.

Does it come with a gasket and filter?

A gasket and filter are not listed as included. Order them separately so the job is done in one pan drop.

What fluid and how much?

MERCON ULV only. Do not fill by quart count; set the level through the fill plug at the 206-215 F check temperature. Sonnax gives about 13 quarts for a dry fill on a 2020 F-150 4x4, but a pan drop takes far less.

Will it fit my Bronco?

The Bronco is on the listed fitment, but it uses the 10R60. Check the number on your existing pan before ordering, or send us your VIN.
