Tranny gauge says hot, but is it?

Hi i just recently purchased a 97 powerstroke (had for two weeks) and the tuck runs great super clean no problems. Today i noticed the tranny temp was reading HOT about 270 degrees. I pulled over and checked the fluid and it was good, didn't smell hot and it was still shifting fine. Im curious if something might be wrong with the gauge, maybe the probe came loose? I had it parked for a solid 3 hours and when i started again the temp was right back up to what it was so something seems wrong and i noticed that the lights to my gauge bar (boost, tranny temp, exhaust temp) wasn't working any more. Anyone info would be great!

Sounds like you might have a bad ground or the gauge has gone out. I would check grounds first, I am guessing you have a common ground for all the gauges so if it's gone out your lights and the gauge itself wouldn't work correctly.

Yeah noticed a loose wire last night playing around under my dash, that's exactly what it was!
