Transmission Filter Kit Guide for the 2006-2011 Fleetwood Bounder
Keep your Bounder's transmission running strong by choosing the correct filter kit for your specific chassis.
- You MUST identify your chassis (Ford or Workhorse) before buying a filter kit; they are not interchangeable.
- Ford F-53 chassis (5R110W trans) have two filters; an internal pan filter and an external cartridge filter that both need changing.
- Workhorse chassis (Allison trans) have an easy-to-change external spin-on filter that requires frequent service.
- A clogged filter can cause serious transmission damage; do not ignore symptoms like harsh shifting or slipping.
First, Identify Your Chassis
Before buying a transmission filter kit for your 2006-2011 Fleetwood Bounder, you must know which chassis your motorhome is built on. The Bounder is the "house," but the engine and transmission are made by a different company. During this period, most gas-powered Bounders used a Ford F-53 chassis, while some used a Workhorse chassis. Diesel models could have a Freightliner or other chassis. The filter kit you need depends entirely on the transmission model, which is tied to the chassis.
How to Tell Your Chassis
- Check the VIN: The first few digits of your Vehicle Identification Number (VIN) can identify the chassis manufacturer. A VIN starting with '1F6' or similar often indicates a Ford chassis.
- Look for Emblems: There may be a Ford or Workhorse emblem on the side or rear of your RV.
- Examine the Transmission Pan: The shape of the transmission fluid pan is unique to each transmission model. A quick search online for "Ford 5R110W pan" vs. "Allison 1000 pan" will show you clear differences.
Common Transmissions in 2006-2011 Bounders
- Ford F-53 Chassis: These typically have the Ford TorqShift 5-speed automatic transmission (5R110W). This transmission uses an internal pan filter and often has a separate, external "toilet paper" style filter.
- Workhorse Chassis (W22, W24): These often use an Allison 1000 or 2100 series transmission. Allison transmissions usually have an internal pan filter and an external spin-on filter, which is easy to access and change.
Symptoms of a Clogged Transmission Filter
When a transmission filter gets clogged, it restricts fluid flow. This can starve the transmission of the fluid it needs to operate. You might notice:
- Harsh or Delayed Shifting: The transmission may hesitate or slam into gear.
- Slipping Gears: The engine RPMs may rise without the vehicle speeding up.
- Whining or Buzzing Noises: A sound from the transmission area could indicate a struggling fluid pump.
- Overheating: A lack of fluid flow can cause the transmission to run hot, which can lead to major damage.
- Limp Mode: Your RV's computer may put the transmission into a "limp mode" to protect it, limiting your speed and gears.
Choosing the Right Aftermarket Filter
For a heavy-duty vehicle like a motorhome, transmission reliability is key. While OEM filters from Motorcraft (for Ford) and Allison are the benchmark, quality aftermarket parts can be a good option if you choose wisely.
Premium Guard is an established aftermarket brand that offers transmission filter kits. These kits provide an OE-style fit and are a cost-effective alternative to dealer parts. For a standard service interval on a well-maintained RV, a quality aftermarket kit like Premium Guard is a reasonable choice. However, for vehicles under heavy use or if you prefer maximum peace of mind, sticking with the OEM filter is never a bad decision.
A Note on Filter Types
For Ford 5R110W transmissions, there are two filters: one in the pan and one external filter. It is critical to change both. The external filter housing can be difficult to remove; using the correct 6-point 22mm socket is essential to avoid stripping the aluminum cap. For Allison transmissions, the external spin-on filter should be changed regularly, sometimes as often as every other engine oil change.
Estimated Replacement Costs
Prices can vary based on your location and the specific transmission in your Bounder. Allison filter kits are often more expensive than Ford kits.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Filter Kit (Ford/Allison) | $80 - $200 |
| New Aftermarket Filter Kit (Premium Guard) | $46 - $74 |
| Shop Labor | $150 - $400 |
| Total Professional Replacement | $200 - $600 |
Frequently Asked Questions
How often should I change my Bounder's transmission filter?
For Ford F-53 chassis with the 5R110W, Ford often recommends a 30,000-mile interval for fluid and filter changes. For Workhorse chassis with an Allison transmission, many owners change the external spin-on filter every 10,000-15,000 miles and perform a full fluid and internal filter change every 30,000-50,000 miles. Always consult your chassis owner's manual for the most accurate information.
Is changing the transmission filter a DIY job?
For a moderately experienced DIY mechanic, yes. Changing the external spin-on filter on an Allison is very easy. Dropping the transmission pan to change the internal filter is a messy but manageable job. You will need a large drain pan, the correct tools, and a way to safely get under the RV. The biggest challenge is often dealing with the large amount of fluid and ensuring the new pan gasket seals correctly.
Do I need to do a full transmission flush?
A simple pan drop and filter change only replaces about one-third to one-half of the total transmission fluid. A full flush, done with a machine at a shop, replaces nearly all of it. For a high-mileage vehicle with an unknown service history, a simple drain-and-fill with a filter change is often considered safer. For a well-maintained vehicle, a flush can be beneficial.
Are there any recalls for the transmission on these Bounder chassis?
There are no widespread recalls specifically for the transmission filter kits. However, there was a recall for some 2011 Ford F-53 chassis for a faulty gear position indicator cable, which could cause an incorrect gear display. There have also been recalls on some Workhorse chassis for issues unrelated to the transmission itself, such as fuel rail clips and brakes. Always check the NHTSA website with your VIN for the most current information.
