| Note | This performance thermostatic bypass valve only fits vehicles with 5-speed automatic transmissions. Mishimoto does not recommend customers in cold climates install the thermostat bypass to avoid overcooling of the transmission fluid. For Ram trucks, double check that you have a 65RFE transmission before purchasing this product. If you have a column or floor shifter, you likely have a 65RFE transmission. If you have a rotary dial shifter (knob), you likely have a 8HP70 transmission and this product will not fit. |
