545RFE vs. 68RFE: Decoding the Best Transmission for Your Dodge Truck
Tyler SpanglerSelecting the right transmission for your Dodge truck is crucial, especially for heavy-duty work. The 545RFE and 68RFE transmissions each have distinct advantages. The 68RFE offers a higher torque capacity of 680 lb-ft compared to the 545RFE's 545 lb-ft, making it better suited for heavier loads and towing. It also has six gears for smoother driving and potentially better fuel economy, along with more robust internal components and a stronger cooling system, providing greater durability under heavy use. The 68RFE is common in newer models, while the 545RFE is found in older ones. If your primary use involves significant hauling or towing, the 68RFE is the superior choice despite its higher cost. For lighter-duty tasks, the 545RFE may suffice.
