ISUZU NPR TRANSMISSION PROBLEM

2004 Isuzu NPR • 140,000 miles

My a/t oil temp light is staying on but the transmission fluid level is fine. Also sometimes it goes off, should I be concerned or is it a faulty sensor?

The temperature has nothing to do with level. If the light is on right after you start a cold engine, you know it's not overheating yet and you can suspect a defective sending unit or a wiring problem. If the light comes on after driving a while, a problem with an external transmission fluid cooler would be the most likely suspect.
