The Dodge 5-speed manual transmission requires specific fluid for optimal performance and longevity. This guide will help you understand the correct fluid type, change intervals, and procedures for maintaining your transmission.

Recommended Fluid

For most Dodge 5-speed manual transmissions, including the popular NV4500 and NV3500 models, the recommended fluid is:

  • Mopar Manual Transmission Fluid (Part number 4874464)
  • GL-4 rated 75W-90 synthetic gear oil

Many owners have reported good results with Pennzoil Synchromesh fluid as an alternative to the Mopar-branded product.

Fluid Capacity

The typical fluid capacity for Dodge 5-speed manual transmissions is approximately 4 to 5 quarts (3.8 to 4.7 liters). However, always consult your vehicle's owner manual for the exact specification.

Change Interval

Despite some owner's manuals stating that the factory-installed fluid doesn't need changing, it's generally recommended to:

  • Change the fluid every 30,000 to 60,000 miles (48,000 to 96,000 km)
  • Or every 3 to 5 years, whichever comes first

Regular fluid changes help maintain smooth shifting and protect internal components from wear.

Fluid Change Procedure

Here's a basic overview of the fluid change process:

1. Warm up the transmission by driving for about 15 minutes

2. Lift and secure the vehicle safely

3. Locate the fill plug on the side of the transmission

4. Remove the drain plug at the bottom and allow fluid to drain completely

5. Clean and replace the drain plug

6. Using a pump, fill the transmission through the fill hole until fluid starts to overflow

7. Replace the fill plug and torque to specification

Always use caution when working under a vehicle and dispose of used fluid properly.

Important Considerations

  • Never overfill the transmission, as this can lead to seal damage and fluid leaks
  • Avoid using GL-5 rated gear oils, as they can damage brass synchronizers
  • If you hear grinding or difficulty shifting, the fluid may need to be changed or there could be internal wear

By using the correct fluid and maintaining a regular change schedule, you can significantly extend the life of your Dodge 5-speed manual transmission and ensure smooth operation for years to come.

FAQs About Dodge 5 Speed Manual Transmission Fluid

    • Can I use ATF in my Dodge manual transmission?
      No, automatic transmission fluid (ATF) is not recommended for most Dodge manual transmissions. Stick to the specified manual transmission fluid or GL-4 rated gear oil.
    • How do I check the fluid level in my transmission?
      The fluid level should be checked at the fill plug. If fluid drips out when the plug is removed, the level is correct. If not, add fluid until it begins to overflow.
    • What happens if I use the wrong fluid?
      Using incorrect fluid can lead to poor shifting, accelerated wear, and potential damage to synchronizers and other internal components.
