Diagnostic Strategies

ROAD TEST PROCEDURE
Road test the vehicle. Make fifteen to twenty 1-2, 2-3, 3-4, and 4-5 upshifts.

Perform these shifts from a standing start to 72 km/h (45 MPH) with a constant throttle opening of 20 to 25 degrees.

With speeds below 40 km/h (25 MPH), make five to eight wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.

With the scan tool, read Transmission DTCs.
