285/75-16
In-tow #5000 boat
Outside Ambient temp 95°-100° - 0% humidity
Trans fluid 1 week old - Changed regularly
A/C running 100%
36 miles total - one way
~55min driving time
Max trans temp 201°
Min trans temp 143°
Average trans temp(towing) 175°
Max water temp 204°
Average water temp 188°
Max trans temp was reach at 55-MPH at beginning of route on long gradual grade
Used trans braking last 4 miles down steep grade to lake Max trans temp 185°
Leaving lake saw highest water temp but max trans temp was 195°
Cooler trans temp when trans torque converter was locked
90% of braking is done by transmission last 12 miles to lake
Leaving the lake the first ~4Miles is 90% 2ND gear, 50MPH, 3800RPM.
Trans temp would move quickly (up and down) from 190° to 175° during route
On my next trip I will not use OD. Im thinking the higher RPM will net lower trans temp at 55-MPH.
Lake water temp - 75°
Boats max speed 47MPH
