In 2000, the Cummins-equipped Dodge Ram pickups were offered with two transmissions: a heavy-duty five-speed manual NV4500 and a four-speed automatic 47RE. This pairing covered the primary customer needs for diesel performance, towing, and daily driving.
Two primary transmission options
The 2000 Cummins Ram lineup mainly used two drivetrain configurations to match different usage patterns:
- NV4500 5-speed manual transmission — a rugged manual option favored by owners who value simple, durable shifting and strong low-end torque handling for heavy towing.
- 47RE 4-speed automatic transmission — an electronically controlled automatic that offers convenience and smooth shifts, commonly chosen for daily driving and longer trips.
In practice, buyers and fleets could choose between the manual for maximum control and reliability or the automatic for ease of use in everyday driving and towing scenarios. Regular maintenance, including transmission fluid changes and proper torque converter issues for the automatic, helps extend life for either option.
How to identify which transmission is in your truck
If you’re trying to confirm the exact transmission in a 2000 Cummins Ram, use these methods to verify:
- Check the shift pattern and pedal setup — a clutch pedal indicates the NV4500 manual; no clutch typically means an automatic (though some automatics have manual-shift capability).
- Look for a transmission identification tag or stamping on the case — the NV4500 and 47RE have distinct codes.
- Consult the build sheet or VIN decode — the factory order usually lists the transmission type; your dealer can decode the VIN for you.
Locating these identifiers will help you confirm whether your 2000 Cummins Ram uses the NV4500 manual or the 47RE automatic, which is useful for maintenance, parts compatibility, and potential updates.
Summary
The 2000 Cummins-powered Dodge Ram offered two main transmissions: the NV4500 five-speed manual and the 47RE four-speed automatic. Your choice depended on preference for manual control versus automatic convenience, with each option supporting the truck’s heavy-towing and long-haul capabilities. Proper maintenance remains key to longevity for either transmission.
