Replace the problematic factory thermal bypass valve in your 2013-2018 Dodge Ram 6.7L Cummins before it causes catastrophic failure with the Smashed Performance Transmission Cooler Thermal Bypass Valve. The OE thermal bypass valve is designed to route bypass the transmission cooler in cold temperatures in order to bring the transmission up to operating temperature faster. Unfortunately, the bimetallic valve commonly fails in the closed position. When this happens, the fluid bypasses the cooler and it is essentially eliminated from the loop causing hot transmission fluid to constantly circulate right back into the transmission, never, or barely, passing through the cooler at all.

Smashed Performance’s Thermal Bypass Valve Upgrade utilizes an unrestricted straight through design, eliminating the recirculation aspect of the factory TBV. No more having to worry about when the factory part will fail you. By removing the passageway that returns hot fluid back to the transmission, fluid restriction is reduced, lowering overall transmission temperatures. A transmission that runs cool will last longer than one that’s always hot. Installation is just like installing the OE part, requiring no cutting or modifications to the factory lines.

FEATURES:

  • Direct Replacement
  • Eliminates Hot Fluid Recirculation
  • Cooler Transmission Temperatures
  • No Modification Needed For Installation
  • Replaces Factory Thermal Bypass Valve
  • Fits 68RFE & Aisin AS69RC Transmissions
  • Replaces OE Part #: 68186711AA & 68186711AB

Note: Will also fit Hemi trucks equipped with a 545RFE, 65RFE, or 66RFE transmission.

Great value
Size: 18-26 Expedition, 15-26 F-150, 18-26 Navigator
The engine air filter fit perfect. The cabin air filter was a bit of a challenge fitting. seemed to be a bit larger but it went in and got the cap back on the box. For the price you cant beat it. Would buy again!

Great Filter Set for Allergy‑Sensitive Families and MPG‑Minded Drivers
Size: 21-25 TLX, 18-25 Odyssey
I bought this set because I prefer handling routine maintenance myself, especially cabin and engine air filters, rather than paying dealership prices for simple jobs. The package included one cabin air filter and one engine air filter, plus a full backup set for the next service interval. Both filters installed easily and fit the 2018 Honda Odyssey exactly as expected. No trimming, no forcing, and no alignment issues. The cabin filter seated cleanly in the glove‑box housing, and the engine filter dropped into the airbox without any airflow restriction or sealing gaps. This setup is ideal for Odyssey owners who want to maintain optimal cabin air quality—especially helpful for families with allergies—and for drivers looking to keep engine airflow unrestricted for the best possible MPG and throttle response. It may not be necessary for anyone who relies exclusively on dealership service or doesn’t perform their own maintenance. Overall, this is a straightforward, high‑value filter set that installs cleanly and supports both air quality and engine efficiency for DIY‑minded Odyssey owners.
