ATS Cooler Block for 68-RFE and Aisin AS69RC Transmissions: Essential Upgrade for Optimal Performance
Upgrade your Dodge truck equipped with a 68-RFE or Aisin AS69RC transmission with the ATS Cooler Block—an essential modification to ensure the longevity and reliability of your transmission. Dodge's original design includes a transmission cooler bypass valve that is intended to accelerate transmission warm-up. However, this valve often fails, leaking or sticking in the bypass position, which can lead to the transmission cooler being effectively removed from the circuit. This results in elevated transmission temperatures, potentially causing severe damage over time.
The ATS Cooler Block addresses this critical flaw by replacing the faulty bypass valve design, ensuring that 100% of the transmission cooler flow is directed through the cooler. This modification significantly reduces transmission temperatures, enhancing performance and extending the life of your transmission, especially during demanding driving conditions.
Key Features:
- Eliminates Faulty Design: Replaces the unreliable bypass valve to ensure consistent and effective transmission cooler operation.
- Improved Cooling Efficiency: Forces all fluid through the transmission cooler, leading to lower operating temperatures.
- Durable Construction: Built to withstand the rigors of heavy-duty use, enhancing the overall performance of your transmission.
- Easy Installation: Includes ATS Thermal Bypass and quick release cooler line fittings (depending on your model year, these fittings may or may not be required).
Upgrade your transmission cooling system with the ATS Cooler Block and enjoy peace of mind knowing your transmission is protected from excessive heat and wear. This essential component is a must-have for any truck owner seeking reliable performance from their 68-RFE or Aisin AS69RC transmission.
