Transmission Temps and a better cooler.
So after our first weekend trip with our (new to us)2011 E450 6.8L Class C MH from Cruise America. I noticed the transmission temp hovered around the 210-220*F range. I am using a Bluetooth dongle plu...

As long as your trans temps come back down when the load is reduced things are working as they should. Any trans under load will generate higher temps, 215 to 230 for brief periods should not be a problem.
I recently saw 230 for about 30 seconds but we were climbing out of Panamint Springs in Death Valley with an ambient temp of 104(fully loaded and pulling a 960# trailer/motorcycle). As soon as I backed off the throttle dropping us back to 40 mph from 45 the temp dropped like a stone and the engine coolant temp never rose above 220.
This was a very rare event with normal operating trans fluid temps running around 185 to 210 on our 2012 E-350, V-10 (24' Class C), with the 5 speed Torque Shift trans. I did switch to pure synthetic trans fluid when I bought the coach and that certainly helps.
The key to this equation is to know what your trans temps are, (I use a Scan Gauge), and then engage the Tow Haul mode sooner rather than later to help control/dissipate the heat before it becomes an issue.
As always..... Opinions and YMMV.
