Frequently Asked Questions
How many automatic transmission parts fit the 2014 Ram 4500?
Our catalog currently lists 24 automatic transmission parts for the 2014 Ram 4500 across 10 subcategories and 12 brands, covering both the 6.4L V8 and the 6.7L L6 DIESEL Turbocharged. Each part is matched to the engine(s) it fits.
Do automatic transmission parts differ between 2014 Ram 4500 engines?
Yes. Every automatic transmission part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of automatic transmission problems on a 2014 Ram 4500?
Common symptoms include delayed or harsh engagement, slipping under load, fluid that smells burnt, or shuddering at light throttle around 40 mph. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the filter and pan gasket with every fluid service, and flush the cooler lines when replacing a failed unit.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2014 Ram 4500 was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2014 Ram 4500?
First match the engine — each row shows which engine(s) the part fits. Then use exactly the fluid specification in the notes — automatic transmissions are the least forgiving component on the vehicle about fluid choice. The notes column carries position and trim qualifiers where they apply.
