Transmission Filter Kit Replacement for the 2018-2024 Fleetwood Bounder
Keep your motorhome's automatic transmission shifting smoothly by maintaining this critical part.
- You must identify if your Bounder has the 6-speed (2018-2019) or 10-speed (2020-2024) transmission to buy the correct filter.
- Symptoms of a clogged filter include harsh shifting, whining noises, and burnt-smelling fluid.
- For a heavy motorhome, changing the filter and fluid every 30,000-50,000 miles is a good practice for preventing major repairs.
- Be aware of safety recalls for the Ford F-53 chassis concerning the rear axle and instrument panel, which a dealer can check for you.
Understanding Your Bounder's Transmission
When shopping for a transmission filter for your 2018-2024 Fleetwood Bounder, the most important thing to know is which Ford F-53 chassis and transmission you have. Ford made a significant change during this period. Failure to choose the correct part will result in an incorrect fit.
Critical Part Alert: Two Different Transmissions Used
To get the right filter, you must identify your transmission. Check your vehicle's build date or owner's manual.
- 2018-2019 Models: These typically have the 6.8L V10 engine with the 6-speed 6R140 TorqShift transmission.
- 2020-2024 Models: These typically have the new 7.3L V8 engine with the 10-speed 10R140 TorqShift transmission.
The filters for the 6R140 and 10R140 are not interchangeable.
OEM vs. Aftermarket Quality
The original filter on your Bounder is a Motorcraft part. For owners looking for a replacement, high-quality aftermarket options provide reliable performance. Brands like Wix are well-regarded in the industry and are a dependable alternative to the more expensive OEM part. These aftermarket kits often meet or exceed original specifications. Many modern Ford transmissions, including the 10R140, use a sturdy, reusable transmission pan gasket. For this reason, some filter kits may not include a new gasket. Unless your original gasket is leaking or damaged, it can usually be cleaned and reinstalled.
Vehicle-Specific Issues and Recalls
While there are no recalls specifically for the transmission filter, owners of the 2018-2024 Fleetwood Bounder should be aware of several important safety recalls issued by Ford for the F-53 chassis:
- NHTSA Recall 21S17: Affects some 2020-2021 models. These chassis may have been built with an insufficient amount of rear axle lubricant. This can cause bearing failure, leading to a loss of power and the inability to shift into park. Symptoms include a metallic grinding or whining sound from the rear of the motorhome.
- NHTSA Recall 24C32: Affects some 2024 models. An instrument panel software error can cause the gear position (PRNDL) not to display correctly. Dealers will update the software free of charge.
- TSB 16-0106: Some 2016-2017 models may experience a failure to downshift when going down a hill in Tow/Haul mode. This can be fixed with a software update at a dealership.
A common issue on older F-53 chassis that can be mistaken for a bad transmission filter is erratic shifting caused by faulty electrical grounds. If you experience shifting problems without other symptoms like noise or burnt fluid, it's worth investigating the vehicle's ground connections.

Frequently Asked Questions (FAQ)
How often should I change the transmission filter on my Fleetwood Bounder?
For a heavy vehicle like a motorhome, it's wise to be proactive. While Ford's official interval can be long, many owners and mechanics recommend a transmission fluid and filter change every 30,000 to 50,000 miles to ensure longevity, especially if you frequently drive in mountains or tow a vehicle.
Is a transmission flush necessary?
A simple pan drop, filter change, and fluid refill is the standard service. This replaces about 7-8 quarts of fluid. A full flush is a more involved process that replaces all of the fluid (nearly 19 quarts for the 6R140) but is not always required unless the fluid is severely contaminated or burnt.
What fluid does my Bounder's transmission take?
The type of fluid is critical. The 6-speed 6R140 transmission uses Motorcraft MERCON LV fluid. The 10-speed 10R140 transmission uses Motorcraft MERCON ULV fluid. Always use the correct type to avoid transmission damage.
Can I replace the transmission filter myself?
Yes, this is a feasible DIY job for someone with mechanical experience, but it is messy. It requires safely lifting and supporting the large vehicle, draining the fluid, dropping the transmission pan, replacing the filter, cleaning the pan and magnet, and reinstalling everything. The most critical part is refilling the transmission with the correct amount of fluid and checking the level properly.
