What transmission fluid does a 2000 Dodge Ram take?

The 2000 Dodge Ram generally uses Dexron III or a Dexron III–compatible automatic transmission fluid, though the exact requirement can vary by transmission type and model. Confirming the specific transmission in your truck is the best way to ensure you use the correct fluid.

Understanding the transmission options in the 2000 Ram

In the 2000 Ram lineup, the automatic transmission depended on the model and engine. The most common configuration on light-duty Ram 1500s used the 46RE/46RH family, while some heavier-duty 2500/3500 variants employed the 47RE. Each family has its own fluid compatibility notes, so identifying which transmission you have is important before shopping for fluid.

• 46RE/46RH (common on many 2000 Ram 1500s and some 2500s with gasoline engines)


• 47RE (heavy-duty transmission used on certain 2500/3500 models and some diesels)

Knowing which transmission is in your truck helps you pick the correct fluid approach and avoids potential shifting issues or wear.

Recommended fluids by transmission type

46RE/46RH (most 2000 Ram 1500s)

Most operators and service manuals for these transmissions around that era specify a Dexron III–type automatic transmission fluid or an equivalent Mercon/Dexron-compatible product. Dexron VI is backward compatible with Dexron III, so it can be used as a modern replacement if you don’t have Dexron III on hand. Some Mopar-branded fluids labeled for Chrysler automatics may also be compatible, but the core requirement is a Dexron III–type specification.

• Dexron III or an equivalent Dexron II/III–type fluid


• Dexron VI (as a modern, backward-compatible alternative)

In practice, using a Dexron III–type fluid or Dexron VI in a 46RE/46RH is widely accepted, provided the product is listed as compatible with Dexron III specifications.

47RE (heavy-duty)

For the 47RE, which appears in some heavy-duty Ram models, the same general guidance applies: use a Dexron III–type ATF or a modern Dexron VI replacement. The key is to choose a fluid that clearly meets Dexron III specification or a compatible Mercon/Dexron blend, as recommended by your vehicle’s manual or service bulletin.

• Dexron III or an equivalent Dexron II/III–type fluid


• Dexron VI (as a modern, backward-compatible option)

Always verify with your specific transmission tag or build sheet, since some late-1990s to early-2000s Chrysler transmissions may see different recommendations in rare cases.

How to confirm exactly which fluid to use

When in doubt, follow a simple verification process to avoid missteps with your fluid choice.

1. Identify your transmission model: check the original window sticker, VIN decoding resources, or the transmission tag on the pan or valve body if accessible.


2. Consult the owner's manual or the Chrysler service bulletin corresponding to your model year and transmission code.


3. Visit a trusted auto parts shop and provide the transmission model and year; they can confirm the correct Dexron-compatible specification for your exact build.


4. Use a reputable Dexron III–type ATF or Dexron VI, and avoid mixing different ATF types unless the manual explicitly allows it.


5. When performing a fluid change, replace the filter if your transmission design requires it and refill to the proper dipstick level with the engine running and in Park/Neutral according to the manual.

Following these steps helps ensure you’re using the correct fluid for your 2000 Dodge Ram’s transmission and helps maintain smooth shifting and longevity of the transmission.

Maintenance tips for transmission fluid health

Beyond selecting the right fluid, regular maintenance can extend transmission life. Consider these practices:

• Check fluid level and condition periodically; burned-smelling, very dark, or gritty fluid is a sign of wear or contamination.


• Follow the service interval recommended in your manual for fluid changes, which may be based on miles or efficiency tests.


• Use a high-quality ATF that matches or is compatible with Dexron III specifications; avoid low-grade fluids that can degrade shifting.


• Address signs of shifting issues promptly (slippage, hard shifts, delays) with a professional inspection and fluid test.

Proper maintenance helps keep the transmission running smoothly and can prevent costly repairs down the line.

Summary

For a 2000 Dodge Ram, the typical automatic transmission fluid is Dexron III–type, with Dexron VI being a widely accepted modern substitute. The exact fluid depends on whether you have a 46RE/46RH or a 47RE transmission, so confirm your model first using the transmission tag or the vehicle’s documentation. When in doubt, consult the owner's manual or a knowledgeable service professional to ensure you use the correct fluid for your specific transmission. Regular checks and timely changes help preserve shifting performance and transmission life.

Bottom line

Most 2000 Dodge Ram automatics take Dexron III–type ATF, with Dexron VI also acceptable as a modern replacement. Identify your transmission type to confirm the exact specification, and follow maintenance guidelines to keep your transmission in good shape.

Related note

If you’re planning a DIY fluid change, gather the proper tools, drain and refill according to the dipstick level, replace the filter if applicable, and test drive to ensure the transmission shifts cleanly within normal temperature ranges.

Summary: The 2000 Dodge Ram typically uses Dexron III–type ATF, with Dexron VI as a compatible modern option. Confirm your specific transmission (46RE/46RH vs 47RE) to ensure exact fluid approval, and follow standard changing procedures for best results.

What kind of transmission fluid does a Dodge Ram use?

The correct Dodge Ram transmission fluid type depends on the model and year, but for many automatic transmissions, it is ATF+4. Some other models may require different fluids, such as Mopar ASRC ATF or ExxonMobile 3309 ATF for specific Aisin transmissions, while older models may use fluids specified for them. Always consult your vehicle's owner's manual or the transmission itself for the exact specification, such as MS-9602 or others, to ensure you use the correct fluid. 
Common transmission fluid types

• ATF+4: This is the most common fluid for many modern Ram automatic transmissions and is often listed under the Chrysler specification MS-9602. 
• Mopar ASRC ATF / ExxonMobile 3309 ATF: Some Aisin transmissions, particularly in heavier-duty models, may require this specific fluid, as indicated on the transmission itself. 
• Other fluids: For specific ZF 8-speed transmissions, other fluids might be recommended or compatible, but it is always best to stick to the manufacturer's recommendation. 

How to find the right fluid

1. Check your owner's manual: This is the most reliable source for your vehicle's specific fluid requirements. 
2. Inspect the transmission: Look for a label on the transmission itself, which often specifies the required fluid type or specification number (e.g., MS-9602). 
3. Use the manufacturer's recommendation: When in doubt, it is best to use the specific Mopar-branded fluid recommended for your transmission to avoid potential damage. 

What kind of transmission fluid does a 2000 Dodge Ram 1500 take?
