Trans Temp Gauge Dancing all over?

[madcat6183]

This is the email I sent GlowShift and Raul at Stealth, but wanted to see if anyone else had the same thing happen to their Trans Temp gauge with sending unit in the tranny pan.

Good afternoon,

I was driving on I70 today and noticed my trans temp gauge was jumping all over the place, and then took note that it was basically going from like 220-260, and then 180-220, then 260-300, etc. When I stopped to fuel up and restarted I noticed the gauge was fine for about 20 minutes then started again. I got home and let the truck run while the gauge was doing this and got under my 250 and checked the lines and checked the ones in the engine bay along with behind the gauge. Seemed like everything was fine but the gauge continued to jump.

I've had them for about 4 years now so just guessing it needs replaced, but was curious if that sounded like the gauge was done or if maybe something else. The temp was 140 when it wasn't jumping around and obviously trans temp doesn't fluctuate like that anyways.

It looks like it's just a simple unplug and replug a new gauge if that is what it sounds like the issue is. I Just don't want to buy a gauge them find out that it's the sending unit, although if that's included in the gauge which it looks like it is, I would just rewire it.

Any advice as it would be greatly appreciated.

I have the GS-C712 for the record and like I said have had it on my F250 for about 4-5 years, so definitely not worried if I should just replace it, I know that placement of the sending unit along with location in the pillar pod makes it prone to wear.

Thanks!
