Shift Diagram

D Range Test
1. Perform road test preparation.
2. Shift the selector lever to D range.
3. Accelerate the vehicle with half and wide open throttle.
4. Verify that 1 -> 2, 2 -> 3, and 3 -> 4 upshifts and downshifts are obtained. The shift points must be as shown in the vehicle speed at shaft point table.
5. Drive the vehicle in fourth, third, and second gears and verify that kickdown occurs for 4 -> 3, 4 -> 2, 4 -> 1, 3 -> 2, 3 -> 1, 2 -> 1, downshift, and that the shift points are as shown in the vehicle speed at shift point table.
6. Decelerate the vehicle and verify that engine braking effect is felt in fourth and third gears.
7. Drive the vehicle and verify that torque converter clutch operation is obtained. The operation points must be as shown in the vehicle speed at shift point table.
8. Select HOLD mode.
9. Accelerate the vehicle with half and wide open throttle and verify that 2 -> 3 upshift and downshift are obtained. The shift points must be as shown in the vehicle speed at shift point table.

S Range Test
1. Perform road test preparation.
2. Shift the selector lever to S range.
3. Accelerate the vehicle with half- and wide open throttle.
4. Verify that 1 -> 2 and 2 -> 3 upshifts and downshifts are obtained. The shift points must be as shown in the vehicle speed at shift point table.
5. Drive the vehicle in third and second gears and verify that kickdown occurs for 3 -> 2, 3 -> 1, 2 -> 1, and that the shift points are as shown in the vehicle speed at shift point table.
6. Decelerate the vehicle and verify that engine braking effect is felt in third gear.
7. Drive the vehicle and verify that torque converter clutch operation is obtained. The operation points must be as shown in the vehicle speed at shift point table.
8. Select HOLD mode.
9. Accelerate the vehicle with half and wide open throttle and verify that second gear is held. The shift points must be as shown in the vehicle speed at shift point table.

L Range Test
1. Perform road test preparation.
2. Shift the selector lever to L range.
3. Accelerate the vehicle with half and wide open throttle.
4. Verify that 1 -> 2 upshift and downshift are obtained. The shift points must be as shown in the vehicle speed at shift point table.
5. Drive the vehicle in second gear and verify that kickdown occurs for 2 -> 1, and that the shift point is as shown in the vehicle speed at shift point table.
6. Decelerate the vehicle and verify that engine braking effect is felt in second gear.
7. Select HOLD mode.
8. Accelerate the vehicle with half and wide open throttle, and verify that first gear is held.
9. Decelerate the vehicle and verify that engine braking effect is felt.
