All Supplies Needed For This Job
Our DIY RV Maintenance Arsenal: Tools and Parts for the Ram 4500 Transmission Service
To perform a successful Ram 4500 transmission service, we gathered the following essential tools and parts:
- Complete Socket Set: A comprehensive set with deep and shallow sockets, ensuring we had the right fit for every bolt.
- High-Quality Torque Wrench: Precision is key for proper bolt tightening, preventing leaks and damage.
- Genuine ASRC Transmission Fluid: We opted for the manufacturer’s recommended fluid for optimal performance.
- New Transmission Filter and Gasket: Replacing these components ensures proper filtration and a leak-free seal.
- Large Drain Pan: To catch the old fluid and keep our workspace clean.
- Cleaning Supplies: For cleaning the pan and magnets, removing any debris.
Step-by-Step Guide: Performing the Transmission Fluid Change on Our Ram 4500
- Draining the Old Fluid: We located the drain plug and carefully drained the old transmission fluid. This step is crucial for removing contaminants and ensuring the new fluid performs optimally.
- Removing the Transmission Pan: We carefully removed the pan, noting the position of the rear bolts, which can be challenging to access. We do not recommend dropping the cross member; just get a swivel socket elbow.
- Inspecting and Cleaning: We thoroughly inspected the pan and magnets for any signs of excessive wear. Cleaning the magnets is vital for removing metallic debris. Replace the magents where they were prior to removal.
- Replacing the Filter and Gasket: We installed the new filter and gasket, ensuring a proper seal. Clean and inspect all areas. We like to use carb or brake cleaner for the mounting surfaces.
- Reinstalling the Pan: We carefully reinstalled the pan, hand-tightening the bolts before using the torque wrench to tighten them to the manufacturer’s specifications. Make sure you get all the bolts started before tightening them all.
- Adding New Transmission Fluid: We added the correct amount of ASRC transmission fluid (9 quarts for us,) checking the fluid level both cold and hot to ensure it was within the proper range.
- Final Checks: We inspected for any leaks and took the Ram 4500 for a test drive, monitoring the fluid level in the following days.
