6R140 Transmission Filter and Pan Gasket Kit, Ford Super Duty TorqShift

This kit is the filter and rubber pan gasket for a fluid service on the Ford 6R140 TorqShift six-speed. It replaces Ford BC3Z-7A098-B, also seen as FT187, and it is what you want on the bench when a 6.7L Power Stroke or 6.2L gas Super Duty is due for service, has been working a trailer or plow all season, or has started taking its time going into gear. Fluid is not included, so you can buy the exact amount your service needs.

What the filter does in a 6R140

The 6R140 filter hangs in the pan and plugs into the pump intake through a neck seal. Every gallon the pump moves to the valve body, the clutch packs and the converter passes through it first. That makes the neck seal as important as the filter media. Sonnax published a case where a 6R140 kept dropping into neutral on hills; with the pan off, the filter fell out "like a box of rocks" because its neck seal had no grip, and the pump was pulling air. Seating a new filter with a fresh seal is the whole point of this kit.

Symptoms that point to the filter or fluid

• Delayed engagement into Drive or Reverse after the truck sits
• Momentary loss of drive on grades, hard stops or sharp turns
• Pump whine that rises with engine speed
• Transmission temperature climbing above normal when towing
• Dark fluid, or a burnt smell on the dipstick

How to confirm before you spend more

Check the fluid level hot and scan for codes. A solenoid or pressure control code is a different problem, covered in our 6R140 pressure control solenoid guide. If there are no codes, drop the pan and look at the magnet and the filter neck. A filter that pulls out with no resistance, or a seal left behind in the pump bore, explains a lot of intermittent engagement complaints. Friction material and metal mean wear has already started. Our 6R140 filter and pan service guide shows what normal and abnormal debris looks like.

Fitment

The listing covers the 6R140 in 2011-2019 F-250, F-450 and F-550 Super Duty, 2011-2022 F-350 Super Duty, 2016-2024 E-350 and E-450, 2016-2024 F-750, 2018-2023 F-53 and F-59 motorhome chassis and the F-650. The diesel and the gas engines share the same 6R140 case, so the filter is common to both. It does not fit the earlier 5R110W, which used a completely different filtration layout, and most 2020-up Super Duty pickups moved to the 10R140 with its own filter. Confirm the transmission tag says 6R140, check the BC3Z-7A098-B number on your old filter, or send us your year and VIN. The full range is on our 6R140 parts page.

Install notes

• Drain warm. Clean the case and pan sealing faces completely; the rubber gasket seals on clean, dry metal.
• Before installing the new filter, look into the pump intake and make sure the old seal did not stay behind. Lube the new seal with Mercon LV and feel it drag as it seats. A filter that slides in loose is a warning.
• Torque the pan bolts evenly in a crisscross pattern so the gasket compresses uniformly.
• Use Mercon LV only. Sonnax lists 8.2 quarts after a pan drain, 10.2 quarts if the valve body came out and 16.2 quarts after a full rebuild.
• Sonnax repeats the warning for Ford 6- through 10-speed units: do not overfill, because it can overheat the fluid. Set the level with the fluid at temperature, following the dipstick instructions for your year.

Rather buy the fluid and filter together? Our 6R140 service kit with 10 quarts of Mercon LV has everything in one box. If heat is the reason you are servicing it, the 6R140 overheating prevention guide covers the cooling side.

Does this filter fit both the 6.7L diesel and the 6.2L gas Super Duty?

Yes. Both engines use the 6R140 case, and the filter is listed for both. Check your transmission tag to confirm it is a 6R140.

Will it fit a 2008 F-250 with a 6.4L?

No. The 2008-2010 trucks use the 5R110W, which takes completely different filters. This kit is for the 6R140 only.

How much Mercon LV will I need?

Sonnax lists 8.2 quarts after a pan drain, 10.2 quarts with the valve body removed and 16.2 quarts after a rebuild. Set the final level hot and do not overfill.

Is the pan gasket reusable?

The factory rubber gasket can often be reused if it is not torn or flattened, but a new one is included so you do not have to gamble.

Why does my truck lose drive on hills after a filter change?

Check that the filter neck seal is fully seated and that the old seal did not stay in the pump intake. Sonnax documented a 6R140 neutral condition caused by a filter neck seal with no grip.
