From what I gather , take the temperature of your transmission fluid at operating temp and you can determine the transmission life expectancy. I would see this very useful when buying a used car or checking if it is worth changing fluid in an older trans.
I would use a non contact thermometer on the pan. Fast, clean and cheap.
Fluid Temp VS. Transmission Life Expectancy
175°F = 100,000+ miles
190°F = 90,000 miles
210°F = 55,000 miles (Pressure Drops)
230°F = 25,000 miles (Valves Stick)
250°F = 17,000 miles (Varnish Forms)
270°F = 4000 miles (Seals & Clutches Burn)
300°F + = TRANSMISSION FAILURE
