Automatic transmission temperature sensor the master debate...

Metric, Imperial, Kelvin.....it would show the delta of the 2. Would need the proper sender and possible weird aircraft voltage. You dont want your trans to run too cold as it will wear faster and the shifts will be inconsistant for a racer. I suppose where you run may be a factor...cold climates, cool the trans and then pipe it through the static temperature of the radiator. Sending very hot trans fluid straight to the rad tank may not help your temperature bottom line let the cooler take the edge off it before it hits the rad. Here's a more common auto app
