Aftermarket 8hp trans thermostat kit

I always suspected that the body shops fed them there.

Took the truck out this afternoon and flogged it a little. Running up and down long grades into a 25MPH headwind. Highest temp I saw was 168. Truck seemed to want to settle in at 165F under a light load.

I still have the full complement of louvers installed as well as the standard 205F thermostat.

That's probably close to the ideal temp for the 8 speed.
