Q: Fluctuating transmission temp gauge

asked by on

I have a 2003 Ford Excursion, diesel. The transmission temp gauge fluctuates anywhere from cold to hot. This just started this morning. What could be the cause? Thank you!

My car has 193000 miles.
My car has an automatic transmission.

The most likely cause of this issue would be a faulty transmission temperature sensor. I would recommend having your transmission temperature sensor inspected and tested for proper function by a qualified professional. If the transmission temperature sensor is functioning improperly, I would recommend having it replaced in order to resolve this issue.
