Transmission Drive Cycle Test
NOTE: The Transmission Drive Cycle Test must be followed exactly. Malfunctions have to occur four times consecutively for codes 49, 59, 617, 618, and 619 to be set, and five times consecutively for continuous code 62 or 628.
After performing the Quick Test, use the following Transmission Drive Cycle Test for checking E4OD continuous codes:
NOTE: When performing the Drive Cycle Test, refer to the Solenoid Application Chart for proper solenoid operation. Refer to the Table of Contents.
1. Record and then erase Quick Test codes.
2. Warm engine to normal operating temperature.
3. Make sure transmission fluid level is correct.
4. With transmission in DRIVE, press Transmission Control Switch (LED lamp should illuminate) and moderately accelerate from stop to 64 Km/H (40 mph). This allows transmission to shift into third gear. Hold speed and throttle opening steady for a minimum of 30 seconds.
5. Press TCS (LED lamp should turn off) and accelerate from 64 Km/h (40 mph) to 80 Km/H (50 mph). This allows transmission to shift into fourth gear. Hold speed and throttle position steady for a minimum of 30 seconds.
6. With transmission in fourth gear and maintaining steady speed and throttle opening, lightly apply and release brake pedal (to operate stoplamps). Then hold speed and throttle steady for an additional five seconds (minimum).
7. Brake to a stop and remain stopped for a minimum of 20 seconds.
8. Repeat Steps 4 through 6 at least five times
9. Perform Quick Test and record continuous codes.
