I'm told that fluid temperature over 300 deg F for very long is death to the
transmission.

But if he is reading 170 on his gauge he is actually exceeding the safe
limit of transmission fluid in the tranny of 200 degrees F (170 +50 = 220).
Maybe this is why GMCs go through so many trannys?
I was wondering why my new "Custom Instrument Panels" transmission temp gage
was reading so low. The gage goes from 150-300 and most of the time it
never gets off the peg. Sometimes it will go up to 170 degrees after
driving up a grade.
Keep in mind the oil in the pan will generally be cooler than the oil
exiting the torque converter by about 50 degrees. 130-140 in the pan under
normal level highway driving is not unusual. 180-190 out of the T.C. seems
to be normal.
With a 150 gauge it is likely the pin will stay pegged, eh?
