What type of transmission fluid does a 2006 Dodge Dakota use?

The 2006 Dodge Dakota uses Mopar ATF+4 automatic transmission fluid for its automatic transmissions. The exact requirement can vary by engine and transmission code, but ATF+4 is the standard specification for this model year in most configurations.


Transmission options in the 2006 Dodge Dakota


The 2006 Dakota offered a couple of automatic transmission setups depending on the engine. Here are the common configurations you might encounter:



  • 3.7-liter V6 paired with a 4-speed automatic (part of the 42RLE family in many Dakotas).

  • 4.7-liter V8 paired with a 5-speed automatic (commonly the 545RFE family).


Note that exact transmission codes and fluid requirements can vary by build and market, so always verify with the door jamb label or owner's manual for your specific vehicle.


Fluid specification for the Dakota's automatics


In practice, both of the automatic transmissions used in the 2006 Dakota are intended to use Mopar ATF+4. This fluid is designed to meet Chrysler’s specifications for these transmissions and supports proper shifting, sealing, and longevity. Do not substitute Dexron VI or other non-Mopar fluids unless a qualified technician confirms compatibility for your exact transmission.



  • Recommended fluid: Mopar ATF+4 (automatic transmission fluid).

  • Compatibility note: ATF+4 is the standard specification for Chrysler automatics of this era; older fluids may not provide reliable operation or could void warranties.


If your current fluid is Dexron or another specification, consult your manual or a professional about converting to ATF+4 to protect the transmission and maintain performance.


Practical maintenance tips for the Dakota’s transmission


Regular maintenance helps prevent shifting problems and transmission wear. Check the fluid level when the engine is warm, follow the service intervals in the owner’s manual, and consider a professional fluid exchange if the vehicle has high mileage or has not been serviced recently.


Summary


For the 2006 Dodge Dakota, the automatic transmissions typically require Mopar ATF+4. This applies whether you have the 3.7L V6 with a 4-speed automatic or the 4.7L V8 with a 5-speed automatic. Always confirm the exact specification on the vehicle’s label or in the owner’s manual, and avoid mixing fluids that aren’t recommended by Chrysler for these transmissions.

What kind of transmission fluid for a 2006 Dodge Dakota?


The 2006 Dodge Dakota requires ATF+4 automatic transmission fluid for its automatic transmission and SAE 75W-90 gear oil for its manual transmission. It is essential to use the correct fluid type for your specific transmission (automatic or manual) to ensure proper function and longevity. 
For automatic transmission:

  • Fluid type: ATF+4 (or Mopar ATF+4) is the official recommendation. 
  • Alternatives: Formulations like Valvoline ATF+4, Castrol Transmax ATF+4, and other multi-vehicle fluids that meet the ATF+4 specification can be used. 

For manual transmission:
  • Fluid type: SAE 75W-90 gear oil is specified for the manual transmission and rear differential.
  • Important: Avoid using 80W as it may not provide adequate protection. 



What transmission fluid does Dodge recommend?


The correct Dodge transmission fluid depends on your vehicle's specific transmission, but ATF+4 is the most common recommendation for many Chrysler/Dodge automatic transmissions, while other models require fluids like ZF Lifeguardfluid8 for 8-speed transmissions or Aisin T-IV/JWS 3309 for certain Aisin transmissions. Always check your owner's manual or a parts list for the precise fluid type and OEM part number for your vehicle. 
Common transmission fluid types for Dodge vehicles

  • ATF+4: This is the standard fluid for many Chrysler and Dodge automatic transmissions, including 5-speed models. It is a full synthetic fluid that is also backward-compatible for vehicles that originally used ATF+, ATF+2, or ATF+3. 
  • ZF Lifeguardfluid8: Specifically required for Dodge models equipped with the 8-speed automatic transmission, such as some Challenger and Charger models. 
  • Aisin T-IV / JWS 3309: This fluid is used in Dodge and Ram trucks with 6-speed Aisin automatic transmissions, such as the AS68RC, AS66RC, or AS69RC. 
  • Dexron VI: While not the primary fluid for most Dodge vehicles, this is a modern, full-synthetic fluid that can be used in older models that specified Dexron III, and is a modern alternative for many other transmissions. 

How to find the right fluid for your vehicle
  1. Consult your owner's manual: The most reliable way to determine the correct fluid is to check your owner's manual, which will specify the exact type and any necessary OEM part numbers. 
  2. Identify the transmission type: Knowing your vehicle's specific transmission (e.g., 5-speed automatic, 8-speed, 6-speed Aisin) will help narrow down the options. 
  3. Look for the specification: The manual will also state the official specification required (e.g., MS-9602 for ATF+4). 



How many quarts of transmission fluid does a 2006 Dodge Dakota hold?


For Automatic Transmission: 545RFE RWD....AP4

Capacity:5 speed 545RFE RWD Total Fill 14.1 quarts.

Is all ATF +4 full synthetic?


Yes, ATF+4 is a synthetic automatic transmission fluid that is licensed by Fiat Chrysler Automobiles (FCA) to meet specific performance standards for Chrysler, Dodge, and Jeep vehicles. It is engineered to provide better thermal stability, reduced wear, and consistent shifting compared to conventional fluids.
 

  • Composition: ATF+4 is a full-synthetic fluid designed to protect automatic transmissions in FCA (now Stellantis) vehicles. 
  • Licensing: The "ATF+4" designation is a registered trademark licensed by FCA, ensuring that products from different brands meet the same quality standards. 
  • Benefits: The synthetic formula offers superior performance over conventional fluids, including better protection against heat, oxidation, and wear, which extends transmission life. 
  • Usage: It is backward-serviceable, meaning it can be used in older transmissions that require ATF+, ATF+2, or ATF+3 fluids, and it is the standard for many newer models as well.
