Detailed Product Description and Specifications

The CSF 20004 automatic transmission oil cooler features a parallel flow core design, which enhances heat exchange efficiency by allowing transmission fluid to flow evenly through multiple parallel channels. This design supports consistent cooling performance, helping to prevent transmission overheating in Dodge Ram 1500, 2500, and 3500 trucks.

Its compact packaging dimensions (32 1/2 inches long, 8 1/4 inches wide, and 19 inches high) and lightweight construction (6.2 lbs) make it suitable for straightforward installation without adding unnecessary bulk. The tube-style inlet and outlet connections ensure a secure fit with existing transmission lines, minimizing the risk of leaks.
