The Durango produced in 2001 uses a four-speed automatic transmission.
The exact variant depends on the engine and drivetrain chosen for the model you’re looking at. In 2001, Dodge paired the Durango’s available engines with one of two main four-speed automatics, and some late-builds saw transitional variants as Chrysler updated transmissions mid-year. To be sure, check the transmission code stamped on the case or the vehicle’s build sheet.
Transmission options by engine
Below is a quick guide to the common engine-transmission pairings found in 2001 Durangos.
- 3.9L V6: 4-speed automatic (commonly the 42RE family)
- 4.7L V8: 4-speed automatic (used with the 42RE/46RE family, depending on production date)
- 5.9L V8: 4-speed automatic (typically within the 46RE/45RFE family, depending on build date)
Note: Exact transmission model can vary by production date, trim, and whether the Durango was built for 4x2 or 4x4 duty. Confirm with the vehicle’s VIN or data plate for a precise match.
How to identify your transmission
If you want to confirm the exact transmission installed on a specific 2001 Durango, use these steps to verify the model code on the transmission itself or your build documentation.
- Locate the transmission code stamp on the side of the transmission case near the output shaft or governor area.
- Compare the code to Chrysler/Jeep/Dodge service literature to identify 42RE, 46RE, or 45RFE.
- Cross-check the engine option (3.9L, 4.7L, or 5.9L) and the drivetrain (2WD vs 4WD) shown on the vehicle’s build sheet or VIN lookup.
- If in doubt, consult a dealership or a qualified mechanic with the VIN to pull the exact factory specification.
By verifying the code, you’ll be able to source the correct transmission service parts and manuals for maintenance or repair.
Summary
For a 2001 Dodge Durango, you’re dealing with a four-speed automatic transmission. The most common pairings are 42RE for many V6 configurations and 46RE or related variants for V8 engines, with some late-models occasionally using 45RFE. Always verify with the vehicle’s VIN/build sheet to identify the exact transmission in your Durango.
