10R80 F150 Fluid Change: Type, Capacity and Cost

Most F-150 owners who ask me about a 10R80 fluid change want three numbers: what fluid, how many quarts, and how much it will cost. The fluid is easy. The quarts are where people get burned, because the 13-quart figure that gets passed around is a dry fill for a rebuilt unit, not what goes back in after a service. And the cost depends on whether the job includes the two things that actually protect the transmission: a new filter and a level check set hot with a scan tool.

This guide is F-150 specific. It covers the 2017-2020 trucks and the 2021-and-later trucks with the 10R80, what Ford's own F-150 owner's manual says about the interval (and one oddity in it), the Ford part numbers for the filter and gasket, the fill quantities Ford's 10R80 service procedure uses, and what is different on a PowerBoost hybrid. Every source is linked at the bottom.

The short answer for an F-150

Which F-150s have the 10R80

The 10R80 went into the F-150 for 2017. Ford's TSB 23-2152 covers 2017-2020 F-150s with the 10R80 and lists labor operations for the 3.5L EcoBoost, the Raptor, the 5.0L and the 3.0L diesel. TSB 24-2254 covers the 2021-2022 trucks and lists hardware for the 2.7L, 3.3L, 3.5L, 5.0L and 3.0L. If the truck is a 2021 or later with a gas or diesel engine, assume 10R80 and confirm with the VIN.

The exception is the PowerBoost hybrid. It uses the 10R80 MHT, which has an electric motor built into the case. Ford's TSB 24-2254 explicitly says it "does not include 10R80 MHT," and the 2021 F-150 owner's manual marks the 150,000-mile transmission fluid and filter line as "non-hybrid vehicles only." Same fluid family, different procedure. If you are working on a PowerBoost, pull the hybrid-specific level check and fill procedure for that truck rather than following the steps below.

What Ford's F-150 manual actually says about the interval

The 2021 F-150 owner's manual lists "Change the automatic transmission fluid and filter" under Other Maintenance Items at every 150,000 mi (240,000 km). Note the words "and filter." This is not a top-off or a machine exchange. Ford's own schedule calls for the filter.

The same manual says to inspect the automatic transmission fluid level at every oil change "if applicable with dipstick." The 10R80 in the F-150 has no conventional dipstick tube. The level indicator is part of the fill plug on the side of the case, so in practice nobody checks it at an oil change unless the truck goes on a lift and gets a scan tool on it.

Here is the oddity. The manual's Special Operating Conditions section for gasoline trucks explains how to time extra services, and its worked example literally says to "perform the 30,000 mi (48,000 km) automatic transmission fluid replacement." The snowplow section also tells owners to follow the severe duty schedule "for engine oil and transmission fluid change intervals." But when you read the gasoline severe-duty tables themselves (towing, extended idling, dusty roads, off-road), none of them contain a transmission fluid line. The manual points to a severe-duty ATF interval that the tables do not list.

My read, as a rebuilder and not as Ford: the example text tells you Ford's writers expected hard-used trucks to get fluid far more often than 150,000 miles. A truck that tows near its rating, plows, or idles on job sites is cooking its fluid. I recommend those trucks get a pan drop and filter every 30,000 to 50,000 miles.

The fluid: MERCON ULV in the transmission, MERCON LV in the transfer case

Ford's Motorcraft fluid page lists MERCON ULV for the 10R rear-wheel-drive and 8F front-wheel-drive families, and it says not to use ULV where MERCON V, MERCON SP, MERCON LV, Type F or several other Ford fluids are specified. The compatibility runs both ways in practice: LV does not go in a 10R80. Ford's 10R80 drain and refill procedure puts it in one line: using any transmission fluid other than what is specified "can result in the transmission not operating normally or premature transmission failure."

The F-150 trap is that a 4WD truck runs two fluids that sit next to each other on the shelf. The 2021 F-150 owner's manual lists MERCON LV (XT-10-QLVC in the U.S.) for the transfer case: 1.5 qt (1.4 L) for the electronic shift-on-the-fly and torque-on-demand cases and 1.9 qt (1.8 L) for the two-speed automatic 4WD case with mechanical lock. TSB 24-2254's parts list does the same thing, LV for the 4WD transfer case and ULV for the transmission. If someone services both on the same visit from one jug, one of them got the wrong fluid.

Ford's fluid page also says to shake ULV bottles before pouring and not to save opened bottles.

How much fluid an F-150 10R80 really takes

Sonnax, working from Ford service information, lists 13.0 qt (12.3 L) of MERCON ULV for a 2020 F-150 4x4 after internal repair. That is an empty case, empty converter and empty passages. A pan drop is nothing like that. The converter, the cooler and the cooler lines all keep their fluid when the pan comes off.

Ford's own 10R80 drain and refill procedure does not give a single "service capacity." Instead it gives a starting point and makes you finish by level:

• Pan or filter removed, or new main control installed: add 4.8 L (5 qt) as an initial fill so the engine can be started.
• Transmission overhauled: add 5.7 L (6 qt) as the initial fill.
• Start the engine, cycle the selector through each position holding about 5 seconds in each, return to Park and idle at 600-750 rpm.
• Add fluid until the level is between the first hatch mark and 6 on the level indicator. Ford says the truck can be driven cold at that level.
• Drive it until the scan tool shows 96-101 C (206-215 F), which purges air from the converter and cooler circuit, then set the final level hot.

Ford recommends a pressurized dispenser with 8-12 qt capacity for the job, which tells you roughly where a pan-drop service ends up. My shop rule: catch and measure what comes out, plan to put about that much back, and have two 6-packs on the bench so you are never short with the pan off.

The F-150 fluid change, step by step

1. Drain

Ford's procedure notes it is not necessary to remove the filter just to drain the fluid; the pan comes off to drain it because most factory F-150 10R80 pans have no drain plug. Since the pan is already off and Ford's 150,000-mile line says "fluid and filter," replace the filter. It is the HL3Z-7A098-A on both the 2017-2020 and 2021-2022 trucks per the TSB parts lists, with the 7T4Z-7Z302-A filter seal and the HL3Z-7A191-B pan gasket.

2. Read the magnet

TSB 23-2152 notes that some fine metal on the pan magnet is normal. Clutch material, chunks of steel, or pieces of a roller clutch are not. If you find those, stop and diagnose before you spend money on fluid. A fluid change does not fix a failing clutch pack, and the customer deserves to know that before they pay for one.

3. Initial fill

Reinstall the pan with a new gasket (see our 10R80 pan bolt torque guide for the fastener specs). Remove the fill plug, pull the level indicator off it, and add 5 qt through the fill hole with a dispenser and Ford's fill tube (tool 307-570). Start the engine and cycle the ranges.

4. Get it hot, then set the level

This is the step that separates a real service from a quick one. Ford's 10R80 level check reads only at 96-101 C (206-215 F) on TFT, engine running, on a level surface. On the Ford 10R80 level check procedure I work from, the correct hot level is between 4 and 5 on the indicator. Sonnax notes the marks vary by application and model year, and owners on hybrid trucks report a different window, so confirm the marks for the exact truck in front of you. Do not overfill. Reinstall the fill plug at 52 lb-ft (70 Nm) per Ford's 10R80 procedure.

Ford also notes that after long highway runs, heavy traffic, hot weather or towing, the fluid must cool down before you get an accurate reading. Sonnax adds that some units have a thermal valve, which is another reason a cold reading tells you almost nothing.

5. Relearn only if needed

A plain fluid and filter service does not require a TCM relearn. If the truck had a shift complaint going in, read our 10R80 F-150 shift problems guide before you blame the fluid change for what happens next.

Why overfilling is the expensive mistake

Sonnax found that as little as 1 qt (1 L) overfilled causes both overheating and fluid venting on Ford 10-speeds. The usual cause is a shop that fills to the top of the mark cold on the lift, which ends up about a quart high once the fluid reaches operating temperature.

Low is just as bad. Ford's procedure states plainly that the truck should not be driven with the fluid low because internal failure could result. Both errors come from the same shortcut: skipping the hot check.

What an F-150 10R80 fluid change costs

Parts for a proper pan drop: a filter and gasket kit (ours is $57.99) and roughly two 6-packs of ULV ($88.99 each on our shelf), so about $235 if you buy two full cases. Labor at an independent shop runs about an hour to an hour and a half for the pan drop, refill, drive to temperature and hot check. That is my estimate from the bench, not a Ford labor time. If you plan to keep the truck and service it more often than Ford's schedule, a drain-plug pan turns every later service into a plug pull. For a full cost breakdown, including exchange machines, see our 10R80 fluid change cost guide.

If a quote comes in well below that, ask whether it includes a new filter and a hot level check with a scan tool.

FAQ

What transmission fluid does a 10R80 F-150 take?

Motorcraft MERCON ULV, part XT-12-QULV (Ford spec WSS-M2C949-A). Ford's Motorcraft page says ULV must not be used where MERCON LV, V or SP is specified, and the reverse applies too. On 4WD trucks the transfer case takes MERCON LV, not ULV, so keep the two bottles separate.

How many quarts does an F-150 10R80 take for a fluid change?

Less than the 13.0 qt dry fill Sonnax lists for a 2020 F-150 4x4, because the converter and cooler keep fluid when the pan comes off. Ford's 10R80 procedure starts with 5 qt after a pan or filter removal, then you add to the level and set it at 206-215 F. Have two 6-packs on hand.

How often should I change the transmission fluid in a 10R80 F-150?

The 2021 F-150 owner's manual lists changing the automatic transmission fluid and filter every 150,000 miles on non-hybrid trucks. Its severe-duty instructions reference a 30,000-mile fluid replacement but the tables do not list one. For towing, plowing or heavy idling, I recommend a pan drop and filter every 30,000 to 50,000 miles.

Does the F-150 10R80 have a dipstick?

Not a conventional dipstick tube. The level indicator is attached to the fill plug on the side of the case, and Ford's procedure reads it with the engine running and the fluid at 96-101 C (206-215 F) on a scan tool. The fill plug goes back in at 52 lb-ft per Ford's 10R80 procedure.

Is the PowerBoost hybrid fluid change the same?

No. The PowerBoost uses the 10R80 MHT. Ford's TSB 24-2254 excludes the 10R80 MHT, and the 2021 F-150 manual marks the 150,000-mile fluid and filter line as non-hybrid only. Use the hybrid-specific procedure and level marks for that truck.
