Transmission Temperature Sensor Addition

[Hobby Racer]

I'm swapping over to a 6 speed this winter and doing the same. A thermal bypass valve to the external cooler. Bypasses the cooler when the temp is below 180F and opens the circuit to the cooler when the temp gets over 180F. It also makes it super easy to put in a temp sensor when you have an external cooler.

When I recorded temps on my 5 speed before I added the external cooler it was quite hot, in excess of 280F after a long track session.
