What temp readings would one expect to see on an a-pillar tranny temp gauge under normal highway/city driving conditions? The sending unit is in the high pressure test port on the drivers side of the tranny.
Noraml would be about 90 deg over ambient air temps.
BTW - Always a good idea to keep Mama happy...!
Since I am relatively new to pulling a load, I just wanted to make sure I wasn't operating in the danger zone, and I never really did get a reading out of that gauge until I started pulling the TT.
Under ALL circumstances, keep the tranny under 250 degrees. That is your danger zone. If you see it creeping into the 225 zone, back out of the throttle and let it breathe.
Other than that... 90-100 above ambient is normal cept for during really cold spells. Its not unusual for my tranny gauge to never come off the bottom peg in the winter time.
