The transmission is the backbone of your RAM. It’s responsible for transmitting large amounts of torque from your 6.7L Cummins powerplant, and that torque generates heat. If that heat isn’t dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it.The stock cooling system of both the 68-RFE and Aisin AS69RC utilize an in-line thermal bypass valve that controls the flow of fluid to the transmission cooler. The purpose of this valve is to prevent transmission fluid from flowing to the cooler until it reaches operating temperature. The thermostat inside this valve is prone to failure, however, and when that happens, the fluid never flows to the cooler and the transmission can overheat. That's why Mishimoto has developed an improved thermal bypass valve kit for your 2019+ Dodge Ram 6.7L Cummins. Our CNC-machined aluminum thermal bypass valve not only looks better than the stock unit, but it performs better too. The Mishimoto thermal bypass valve utilizes a replaceable thermostat that is more durable than the stock thermostat and opens about 10 F earlier. This allows fluid to flow to the cooler sooner, without over-cooling. For owners in hot climates, the Mishimoto valve includes a bypass that allows full flow to the transmission cooler, regardless of temperature. The bypass can be easily swapped out with only a wrench for summer or winter driving. The Mishimoto thermal bypass valve flows better in both configurations than the stock valve for more effective cooling. Cooling fins machined into the valve body add even more heat dissipation. This 2019+ Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit is built to last a lifetime with a durable black anodized finish and our Mishimoto Lifetime Guarantee.

This company lies to you. Ordered a 02 sensor from APPD for my C7 Vette. Paid the highest possible courier service for the fastest possible shipping from Newcastle to France. I needed the part urgently. Ordered at the weekend and called them Monday to confirm all was in hand and explained the part was required urgently. Response from APPD yes we've recieved the order and will ship as soon as its been processed. Called every day for the next 7 days to be told yes its been shipped and this is the shipping number. Turned out it took them till Friday ..5 days later to post it and then the package lay at the courier another week or so. APPD lied to me throughout this whole transaction. The package cleared customs in 2 days and should have been with me in just over week and not over 4 weeks. APPD offereed the postage refunded after I had to start a PAYPAL dispute.. This should have been a straight forward simple part delivery.When it goes wrong you shouldn't lie to your customer. A serious compay would refund the customer not try to fuzz the truth and blame everyone else. I refused the postage delivery refund so you can buy some honesty pills and discuss with your team how to avoid more negative service feedback. If your thinking of ordering parts from APPD scroll on and find another supplier. You dont need or want the hassle of dealing with these people.

Over a month waiting on parts and all I get is it will scan soon week after week. Reordered from US so I could finish build and same parts arrived in one week. Waiting to see if they will refund??

placed an order for parts 13th of feb, all listed in stock, got shipping update for label created on the 16th of feb. I have still not received what I ordered and paid for, no updates. I have been getting the same generic answer "order will be fulfilled today" for nearly 2 months now when trying to enquire. Quite disappointing as I have been unable to finish off my car due to waiting on the final fuel system parts for over 2 months now.
