Transmission Filter Kit Guide for 2012-2017 Fleetwood Southwind
Keep your Southwind's transmission shifting smoothly by understanding its essential filter kit.
- Verify if your Southwind has the 5-speed (2012-2015) or 6-speed (2016-2017) transmission before ordering a filter kit.
- Use only the correct transmission fluid: MERCON SP for the 5-speed and MERCON LV for the 6-speed.
- Due to the severe duty nature of RVs, plan to change the transmission filter every 60,000 miles.
- When changing the filter, ensure the old o-ring seal is removed to prevent a catastrophic pressure leak.
Understanding Your Southwind's Transmission
When you own a 2012-2017 Fleetwood Southwind, you're driving a home on wheels that relies on a Ford F-53 chassis. It's important to know that there was a change in the transmission during this period. Models from 2012-2015 are typically equipped with the Ford 5-speed TorqShift 5R110W transmission. Starting in 2016, Ford switched to the 6-speed TorqShift 6R140 transmission. Because the filter kits are different for these two transmissions, you must verify which one is in your specific motorhome before buying a part.
Symptoms of a Clogged Transmission Filter
A dirty or clogged transmission filter can starve the transmission of fluid, leading to serious and expensive problems. Pay attention to these warning signs:
- Harsh or Delayed Shifting: If gear changes feel clunky, slow, or hesitant, it could be caused by low fluid pressure from a clogged filter.
- Transmission Overheating: A restricted filter can reduce the flow of fluid to the transmission cooler. This can cause the transmission to run hot, especially when climbing hills or carrying a heavy load.
- Whining or Buzzing Noises: Unusual noises from the transmission area can mean the fluid pump is straining to pull fluid through a dirty filter.
- Limp Mode: In severe cases, your RV's computer might put the transmission into a "limp mode." This locks it into one or two gears to prevent major damage.
Stop and Check
If you experience sudden harsh shifting or your transmission goes into limp mode, pull over safely as soon as possible. Driving with severe transmission symptoms can lead to catastrophic failure, requiring a complete and costly replacement.
Choosing an Aftermarket Transmission Filter Kit
For a critical part like a transmission filter, quality is key. The original Ford/Motorcraft filter is always a safe bet. However, high-quality aftermarket brands can offer comparable performance at a better price. Since the transmission is a Ford part, you are not looking for a "Fleetwood" filter, but one that fits the specific Ford transmission in your chassis.
Premium Guard: Premium Guard is a known aftermarket brand that produces a wide range of filters. Forum discussions and reviews suggest they are a well-built, value-oriented option. For a standard component like a transmission filter, a quality aftermarket part like this should perform well for regular maintenance.
Pro Tip: Always make sure the old o-ring or gasket from the filter neck is removed from inside the transmission housing before installing the new filter. Leaving the old one in can cause an internal pressure leak and transmission failure.

Frequently Asked Questions (FAQ)
How often should I change the transmission filter on my Southwind?
Because a motorhome is considered "severe duty," experts recommend changing the transmission fluid every 30,000 miles and the filter every 60,000 miles. This is more frequent than the schedule for a light-duty truck but is critical for protecting your investment.
Is this a DIY job?
For a person with moderate mechanical skills, yes. The job involves draining the fluid, carefully dropping the large transmission pan, replacing the filter, cleaning the pan and magnet, and reinstalling everything with a new gasket. It is messy, and you must tighten the pan bolts to the correct torque specification to prevent leaks.
What kind of transmission fluid do I need?
This is extremely important. For the 5-speed 5R110W (2012-2015), you must use fluid that meets the MERCON SP specification. For the 6-speed 6R140 (2016-2017), you must use MERCON LV. Using the wrong fluid can cause poor shifting and internal damage.
Are there any recalls or TSBs I should know about?
While no recalls exist for the filter itself, Ford has issued TSBs for the transmissions. TSB 16-0106 was released for some 2016-2017 F-53 chassis models that would not downshift correctly in Tow/Haul mode, which is fixed by a PCM reprogram. Always check for any open recalls or service bulletins related to your specific vehicle's VIN.
