Transmission temperature

My RV transmission has been running at 210 to 225 on the freeway. I just added a 10" electric fan to the tranny cooler and was surprised to see that my RV still got up to 210 on the freeway. I hear other people say their RVs run at 150 - 180. My tranny has new fluid and the cooler is clean. The weather has been around 80.

The RV is a 1997 460 F53 with the full Banks system. I'm wondering if I need a new / larger cooler or should I be happy with 210 on the freeway?

    If you can, unhook the Banks transmission controller------------that could be your problem.

    How much air flow do you have?
    If I run my chrome classics cloud rider grill insert on my truck it runs 10-15 degree higher on the trans temp

    Have you thought about trying one of these Trans Pan. I had one n my 1990 Ford F350 Class C. It increases the amount of fluid, plus has it's own built in cooling unit.

    That is about the same temps that mine runs when towing the toad. I have the same setup as yours. I plan to install a larger cooler this fall when I change out the radiator to maybe lower the temps just a bit.

    Your E4OD should be running 70 to 100 degrees above the ambient temperature. Definitely more cooling capacity is needed. Although your tranny will survivr at the temps you are seeing, statistics say you will have a reduced tranny life more so than if it were running cooler. Are you aware of people adapting the 6.0L diesel engine cooler to their Ford diesels for better cooling. Would you be able to mount a 6.0 cooler in the radiator airflow on your vehicle?
