Trans temp on new fleetwood 40x
I'm trying to get a base line on the Allison tran temp. Off highway 170 - 180. Highway flat and level 190 - 200. I've seen it higher than the engine temp for a very short period. Is this normal on rel...

The issue is reasonably complex. There is no single "approved" location for the transmission temperature sensor. Some are in transmission itself, some on line IN on the transmission cooler and some on the OUT line from the transmission cooler.
And, the Allison 3000 and 4000 series transmission's torque converters are locked up in "high" second and always locked in all higher gears.
So, transmission temperature is really a combination of heat produce in the transmission and in most applications also heat picked up/not dissipated by the in-radiator transmission cooler.
But, bottom line, your temperatures are in the normal range.
