Trans temp gauge----WTF???

[Oilman]

Ok guys, I'm back, unfortunately it's because i have a a a slight problem.
This morning, my trans temp gauge started going crazy. It seemed to be when I push the go pedal. The gauge will peg to the high side, then as I let off of it, will come down some, but still reading high IMO (165-170). This truck in august pulling 28" G/N on the interstate usually only sees 175 or so. I'm running empty now. Trans fluid is down on the low side of safe marks, and will add a qt when I get home, sender is in pan (Mag-htec deep).
Any thoughts???TMTT

Is it an ISSPRO EV trans guage? and where did u get it from?

I got the isspro EV white faced gauge set about 4 years ago from Diesel manor. I'm thinking ther may be a short to ground somewhere near the trans that is shorting when thing flex a little bit, I dunno:dunno:

yea that could be it mine ended up grounding out in the guage pod and it would pin itself (dash pods suck)

mine did the same thing yr or 2 ago and i jus had them for not even a year. got them from diesel manor emailed them got a new box no questions asked but idk what the problem was figured that would help

they are on the dash, and it does rattle a little bit, so maybe I'll check for external shorts after christmas, and if I can't find an issue, I'll see if I can duplicate the problem on the bench(read---tailgate) and replace the gauge if necessary. I have had a few dealings with Dieselmanor, and they have been great, but I wouldn't expect them to warranty a 4 year old gauge if it is bad. thanks for the replies/suggestions. Maybe I'll find time to post more instead of just lurking so much.

Merry Christmas to all.:smokin:

What is the "Normal" and "High" operating temps...Mine will get to 190 climbing hills empty...easy plowin will reach 210-220 sometimes...sensor is in the cooler line...Idiot light doesn't come on. :97DodgeCTD: ..Isspro guages from DM..When it get to the 220ish temp, I check the fluid and it is at the full mark...operating fluid level is ok...:dunno:..
