Dennis have you changed filters and replaced fluid with new transynd? If not that would be my first move.

I typically would trust a digital input but since you asked where the sensor was located I might infer you don’t trust the sensor. Easy enough to shoot the upper inlet pipe to the cooler with an IR gun to cross check

I have not changed the fluid or filters yet.  It's on my short list.

Good idea with the IR gun.  

I use your bluefire template and it must be "in range" because it doesn't change colors like the water temps does when it gets hot.  Unless you didn't do that with the trans temp guage.
