Not sure on a 2013,
On my 2007 with a Scan Gage reading water temperature. It will not go into 4th gear until the water temperature is above 130 degrees F. U340 transmission diagram shows the shift selector is an input to the ECM. Then there are electrical signals sent to the transmissions shift internal solenoids and it has an internal AFT temperature sensor in it also. |
