NP273 operating temp ?
curious what a typical operating temperature range is for the ESoF tcase behind the 4r100.
on a road trip towing and as usual I check my tires,rotors, hubs and Diff at every stop, better to catch a problem early me things.
checked the temp of the tcase just out of curious and was surprised to see it at 137*
ambient is 50*
trans 150*. ( might need to restrict some air flow)
tire sidewall 92*
diff 150*
hubs 65*-75*
ujoint caps < 90*
anyhow, just curious if anybody else checks their tcase temps or knows of a factory spec
edit, and 100% confirmed front shaft is not spinning

Seems fine, its always in motion and its directly coupled to the transmission so there has to be some heat sink going on. Either way you are well below normal Mercon operating temperatures so I wouldn't worry.

no worried, just curios since i just started tracking the tcase.
i have a long history of data on all the other parts but with recent tcase failure post figured i would start tracking it. that and ujoint caps added to my routine.
