Transmission Drive Cycle Test

NOTE: The transmission drive cycle test must be followed exactly. Malfunctions have to occur 4 times consecutively for continuous codes P0781, P0782 and P0783 to set, and 5 times consecutively for continuous codes P0741 and P1741 to set.
  1. After repairing any engine performance-related DTCs, erase remaining transmission codes. Warm engine to normal operating temperature. Ensure transmission fluid level is correct.
  2. With transmission in Overdrive, moderately accelerate from a standstill to 50 MPH. Hold speed and throttle position steady for at least 15 seconds.
  3. While maintaining speed with transmission in Overdrive, lightly depress brake pedal and release (to operate brakelights). Hold speed for at least an additional 5 seconds. Bring vehicle to a complete stop for at least 20 seconds with gearshift lever in "D" position.
  4. Repeat steps  2 and  3 at least 5 times. Perform QUICK TEST and record any continuous memory codes. See RETRIEVING DIAGNOSTIC TROUBLE CODES (QUICK TEST)  .
