  2. Move selector lever to "D" position. Depress accelerator pedal halfway. Vehicle should start from 1st gear. Verify 1-2, 2-3 and 3-4 upshifts occur at specified speed. Refer to SHIFT SPEED SPECIFICATIONS tables. Also See Figure.
  3. Lock-up occurs at speeds relative to throttle opening in D4. To verify lock-up speeds, see LOCK-UP SPEED SPECIFICATIONS table. Lock-up condition should be maintained for more than 30 seconds. Lock-up state is released upon deceleration. Confirm transmission mode switch is in AUTO position, overdrive switch is in ON position and selector lever is in "D" position.

Release accelerator and verify 2-3, and 3-4 upshifts. Check shift points and specified speeds. Refer to SHIFT SPEED SPECIFICATIONS tables. Also See Figure.
  5. Confirm transmission mode switch is in AUTO position, overdrive switch is in ON position and selector lever is in "D" position. Accelerate vehicle to 4th gear using half-throttle. Release accelerator and switch overdrive to OFF position. Verify 4-3 downshift.
  6. While still in 3rd gear, move selector lever from "D" to "2" position. Downshift should occur and deceleration should occur by engine braking. While still in 2nd gear, move selector lever from "2" to "1" position. Downshift should occur and deceleration should occur by engine braking.
