Modified Transmission Thermostat, C43

As an available add on to our split transmission cooling system, we perform a custom modification to the OEM thermostat to make it stay open 100% of the time. This is beneficial when running the split cooling system be cause it lowers transmission temperatures more than what is possible with the thermostat normally operating. This is recommended for those who don’t mind waiting longer for their transmission to warm up. Without the split cooling system, this modification will negatively impact intake temperatures and is not advised. Core Option: You are required to pay a core fee of $100 unless they are sent in advance. Upon receipt of your stock thermostat this fee will be refunded to you.
