Here's why:
* Multiple Transmission Options: Dodge 2500s in 2001 came with a variety of transmissions (46RE, 47RE, 48RE, etc.). Each transmission uses a different type of ATF.
* Fluid Compatibility: Using the incorrect ATF can severely damage your transmission.
How to find the right ATF:
1. Locate your transmission: Check the sticker on your transmission (usually on the driver's side near the bell housing). It should list the transmission model (e.g., 46RE).
2. Consult your owner's manual: This manual should have a section on fluids and specify the correct ATF for your transmission.
3. Check with a reputable mechanic: A qualified mechanic can identify your transmission and recommend the appropriate ATF.
4. Contact a Dodge dealership: They can provide the correct information based on your vehicle's VIN.
Important Note: Never use ATF that is not specifically designed for your transmission.
