D Range Test
1. Perform road test preparation.
2. Shift the selector lever to D range.
3. Accelerate the vehicle with half- and WOT.
4. Verify that 1 -> 2, 2 -> 3, and 3 -> 4 upshifts and downshifts are obtained. The shift points must be as shown in the table below.
5. Drive the vehicle in 4GR, 3GR, and 2GR 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 table.
6. Decelerate the vehicle and verify that engine braking effect is felt in 4GR and 3GR.
7. Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown in the table.
8. Select HOLD mode.

9. Accelerate the vehicle with half- and WOT and verify that 2 -> 3 upshift and downshift are obtained. The shift points must be as shown in the table.

S Range Test
1. Perform road test preparation.
2. Shift the selector lever to S range.
3. Accelerate the vehicle with half- and WOT.
4. Verify that 1 -> 2 and 2 -> 3 upshifts and downshifts are obtained. The shift points must be as shown in the table.
5. Drive the vehicle in 3GR and 2GR and verify that kickdown occurs for 3 -> 2, 3 -> 1, 2 -> 1, and that the shift joints are as shown in the table.
