Contour Enthusiasts Group Archives Forums General Troubleshooting ATX Maintenance

AA737-823,

The PCM in our Contours, reads the TFT (Transmission Fluid Temperature)
for optimal shifting based on fluid temperature.
The Air Temperture, as well as the Engine Coolant Temperature,
and the Emissions being in CLOSED LOOP all affect the point at
when the ATX will shift into Overdrive.
If the Emissions is not able to achieve Closed Loop,
the ATX will not shift into overdrive.
