Temperature program 2

If the oil temperature rises to 135°C lock-up is activated on 3rd gear. A lower gear is then selected in order to minimize a rise in temperature. With lock-up activated there is no slip in the torque converter, which means that temperature falls.

Temperature program 2 does not function when: 

• Limp Home is activated

Is disengaged when: 

• The temperature has fallen to 130°C
• The Limp Home mode has been entered
• The temperature has fallen to 135°C

If the temperature rises to 145°C a reduction of engine torque to 200 Nm takes place.

If the temperature rises to above 155°C for more than 10 seconds then diagnostic trouble code P0218 is registered. A bus message "TRANSMISSION OVERHEATING", is sent from TCM, this is shown in the SID display.
