I have a 2016 Honda Pilot which I use for towing a trailer. I have added a transmisson cooler and while I did it also added a temperature sensor. When driving the sensor works as expected showing ambient temperature when I start and rising to 150-180 range during normal driving with nothing in tow. When towing it more often is in the 175-200 range. I have had a number of instances where the "Transmission Too Hot" idiot light comes on but it doesn't seem to correlate with the temperature reported by the sensor. On one recent trip the sensor got as high as 225 on a particularly long hill towing about 4000 pounds. It went down to about 205 when the terrain leveled out and about 20 minutes later when the sensor read 195 the idiot light came on. On another recent occasion the sensor never got above 200 and the idiot light came on at about 198 and stayed on even when the temp got down to 130 (long downhill with transmission in neutral and relatively cool air outside). Anyone know at what temp it is supposed to come on and go off? Does this behavior make sense? Pretty unhappy that the Pilot can't tow 4000 pounds even with a huge ATF radiator (I had the OEM after market originally, added a second bigger one to try to solve the problem).
