P1942 Transmission adaptation, On a Dodge Durango the ambient temperature sensor is used by the DPLV, heated oxygen sensor circuit and a transmission fluid temperature sensor , If the ambient temperature is not rational in regards to the engine temperature sensor the transmission temperature will adapt to a substituted temperature value, this in turn will effect the 2-3 shift points on the transmission,
On a 2000 dodge ram 1500 pick-up 5.9 magnum engine where is the engine cooling temperature sensor located?
If the transmission is the 3-speed 31TH, the speed sensor is located on the back of the transmission, follow the right side CV halfshaft, and the sensor is mounted right near where the inner CV joint splines into the differential. If it's the 4-speed transmission (not likely), it would be located on the front of the transmission. I suggest getting a Haynes Repair Manual, it should verify the location.
