What Is The Purpose Of Thermostat In Aftermarket Cooler

Question:

What is the purpose of the thermostat in the transmission coole? I was also told there was a check valve that gets stuck. Are they the same and if so could you remove the check valve for better cooling. I live in Phoenix Arizona.

The automatic transmission thermostat fits into the bottom of the coolant expansion tank and controls the temperature of your automatic transmission fluid, ensuring that it is always running at its optimum temperature. The check valve function is very simple they direct flow into or prevent flow from entering specific circuits. I would not remove them.

The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets # D13503 will fit most vehicles with 5/16 inch transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.
