Transmission Cooler Bypass Block For 2013-2017 6.7L Cummins (68RFE/AS69RC) – Billet 6061 Aluminum, Improves Cooling

Own a 2013-2017 Ram with the 6.7L Cummins and an automatic transmission? This billet aluminum block is a popular reliability upgrade. It replaces the factory transmission cooler line fitting, which has a built-in thermostat that can restrict flow to the cooler until the fluid is 'warm enough.' This block eliminates that bypass valve, forcing 100% of the transmission fluid through the cooler from the moment you start the truck. The result? Lower and more consistent transmission temperatures, especially when towing or in hot weather, which can help extend the life of your transmission. It's made from durable 6061 aluminum and comes in a bright red finish. Installation is straightforward (you'll need to reuse or get new fittings), but make absolutely sure it's compatible with your specific transmission model (68RFE or Aisin AS69RC) before you buy.
