Erratic Transmission Gauge

I posted this at another site, but sometimes it seems only certain people can get their questions answered there, so I'll post it here as well:

"The tranny gauge on my truck is acting odd. Yesterday, while towing a small boat, the gauge pegged out at 280. This didn't sound right, so I plugged in my Edge Evolution and per the datastream on it, the tranny was around 180.

I checked the connections at the fuse box and found that they weren't very snug, so I tightened them up. While driving today (no trailer), the gauge read around 50 degrees warmer than the Edge reading. The needle wandered as low as 30 degrees higher and as high as 75 degrees higher.

Does anyone have any suggestions where to troubleshoot this? Should there be such a high temp differential between what the Edge is reading & what the gauge is showing?

333 - I'm only half bad!

your aftermarket gauge is reading off of a different sender than the computer is, so it sounds to me like there is probably an issue with the aftermarket temp sender.......Marc
