Revmax 68RFE Transmission Cooler Thermostatic Bypass

Thanks for the informative post!
Unlike newer engines, I don’t subscribe to “hotter is better” for transmissions.
It bugs me that my company truck runs 190-200 ALL the time, according to the gauge anyway. Empty or loaded. Runs the same temp towing uphill as empty downhill, or close enough.
It also blew the trans at 60k miles. New one still runs 190s.
