Most performance based automatic transmission DTCs require the fault to be detected multiple times before setting a DTC. In many instances the faults musts be detected consecutively a predetermined number of times (up to five). Performing the shift point road test as detailed below increases the likelihood that a DTC sets if a fault is present in the system.
- 3.
Apply minimum throttle and observe speeds when an upshift occurs. Refer to the Shift Speeds chart.
- 4.
With the selector lever in the D position and speed above 80 km/h (50 mph) and less than half throttle, move the selector lever from the D position to manual 2 position and release the accelerator pedal. The transmission should downshift into 2nd gear. With the transmission remaining in the manual 2 position, move the selector lever into the manual 1 position and release the accelerator pedal. The transmission should downshift into 1st gear at speeds below approximately 45-56 km/h (28-35 mph).

If the transmission fails to upshift/downshift, Refer to: Diagnosis By Symptom .
