Buying Automatic Transmission Parts for a 2018 Ram 3500
On this vehicle, the automatic transmission covers the automatic gearbox and its supporting cast — filters, coolers, solenoids, mounts and torque-converter parts.
- Match the engine first. Every automatic transmission part here is engine-specific; each row shows which engine(s) it fits.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the filter and pan gasket with every fluid service, and flush the cooler lines when replacing a failed unit.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions
How many automatic transmission parts fit the 2018 Ram 3500?
Our catalog currently lists 262 automatic transmission parts for the 2018 Ram 3500 across 60 subcategories and 51 brands, covering all 3 engine options (5.7L V8, 6.4L V8 and 6.7L L6 DIESEL Turbocharged). Each part is matched to the engine(s) it fits.
Do automatic transmission parts differ between 2018 Ram 3500 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 2018 Ram 3500?
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 2018 Ram 3500 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 2018 Ram 3500?
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.
