I had a remanufactured 5R110 transmission - supposedly with "heavy duty" options - installed instead of having the original transmission rebuilt. I hope that there is such a thing as a heavy duty way to rebuild the 5R110 5-speed transmission and that we actually wound up with it after dropping $5600.
I can't imagine how the Ford 5-speed transmission can be over-heated pulling only around 11,800 lbs. of motorhome. It seems to me that we shouldn't have to be concerned with over-heating our transmission under these conditions. Are those transmission fluid heat charts above really serious -> one has to keep transmission temperatures way down to 185 degrees or less for 100,000+ mile transmission life??? You could of fooled me!!
Those are recommended pan temperatures, the coolest temps in the transmission, the converter outlet (to cooler) temps can climb higher. Very few people bother to measure the temp at the outlet, and it will be 30-50 degrees higher. Transmissions are expensive, fluid is relatively cheap, change it frequently and keep it cool with extra coolers and deep pans.
