1. Mopar 68218057AB ATF+4 Automatic Transmission Fluid

3. Castrol Transmax ATF+4 Automatic Transmission Fluid

Castrol is another reputable brand in the automotive fluid market. Their Transmax ATF+4 is a full synthetic fluid designed to exceed expectations.

4. Valvoline MaxLife Multi-Vehicle ATF Full Synthetic

Valvoline’s MaxLife is a multi-vehicle ATF designed for a broader range of applications. While it covers a lot of vehicles, always check for ATF+4 compatibility with your specific make and model.

• Compatible with a wide range of vehicles, but check compatibility carefully for ATF+4
• High-performance conditioning agents to prevent leaks
• Improved durability and transmission life
• Enhanced high and low-temperature performance

Pros:

5. Chrysler (68218057AC) Genuine Mopar Fluid ATF+4 Automatic

Another Mopar ATF+4 option, this one might have a slightly different part number, so double check for compatibility with your vehicle’s requirements before purchasing.

• Genuine OEM Dodge/Mopar factory fit part
• Designed for optimal performance in compatible vehicles

Pros:
– OEM quality and performance
– Guaranteed compatibility (when correct part number is used)

Cons:
– Pricey
– Must confirm exact compatibility with your vehicle’s specifications

User Feedback Summary: Similar to the other Mopar option, users appreciate the reliable performance and compatibility, but the price remains a concern for some.

6. Fits-JEEP DODGE CHRYSLER ATF+4 AUTOMATIC TRANSMISSION FLUID

This is another aftermarket brand claiming ATF+4 compatibility. It’s vital to verify compatibility with your vehicle’s specifications before purchasing. I strongly suggest avoiding these less reputable brands if OEM or Valvoline options are available.

• Claims compatibility with Jeep, Dodge, and Chrysler vehicles

Pros:
– Potentially less expensive than OEM.

Cons:
– Unclear manufacturing details and quality control.
– Lack of verifiable certifications.
– Increased risk of transmission issues if the fluid is not genuinely ATF+4.

User Feedback Summary: Limited and unreliable feedback. Avoid until more reputable review information is available.

7. Toyota 00289-ATFWS Lexus & Automatic Transmission Fluid WS

This is a Toyota WS fluid, not ATF+4. Do not use this fluid in a vehicle requiring ATF+4. This is included to highlight the importance of using the correct fluid type. Using the wrong fluid can severely damage your transmission.

• Toyota/Lexus OEM transmission fluid
• Designed for vehicles using WS fluid

Pros:
– High-quality fluid for compatible vehicles.

Cons:
– Incompatible with vehicles requiring ATF+4. Using this will damage your transmission.

Comparison Insights:

While all these fluids aim for reliable performance, OEM fluids like Mopar offer guaranteed compatibility and peace of mind. Valvoline offers good alternatives at more competitive prices with strong performance, but always double-check your vehicle’s requirements. Avoid lesser-known brands without reliable certifications.

Final Verdict:

For the best possible performance and peace of mind, sticking with the OEM Mopar ATF+4 fluid is the safest route. However, if budget is a concern, Valvoline’s ATF+4 full synthetic is a strong contender offering excellent protection and performance at a lower price. Always cross-reference your vehicle’s owner’s manual for the correct fluid specification before purchasing.
