D Range Test

NOTE: The POWER mode and the NORMAL mode are automatically selected by the powertrain control module.





D RANGE (EXCEPT O/D OFF MODE)
1. Shift the selector lever to D range.
2. Accelerate the vehicle with half- and wide open throttle.
3. Verify that 1->2, 2->3, and 3->4 upshifts and downshifts are obtained. The shift points must be as shown in the D range shift diagram.
4. 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, and that the shift points are as shown in the D range shift diagram.
5. Decelerate the vehicle and verify that engine braking effect is felt in fourth and third gears.
6. Drive the vehicle and verify that torque converter clutch operation is obtained. (only for NORMAL mode)

D RANGE (O/D OFF MODE)
1. Shift the selector lever to D range and select the O/D OFF mode.
2. Accelerate the vehicle with half- and wide open throttle.
3. Verify that 1->2 and 2->3 upshifts and downshifts are obtained. The shift points must be as shown in the D range O/D OFF shift diagram.
4. 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 D range O/D OFF shift diagram.
5. Decelerate the vehicle and verify that engine braking effect is felt in third gear.
6. Drive the vehicle and verify that torque converter clutch operation is obtained. (only for NORMAL mode)

NOISE AND VIBRATION
Drive the vehicle in second gear (O/D OFF) and listen closely for any out of the ordinary noise or vibration. The torque converter, drive shaft, and differential can be sources of abnormal noise and vibration if they are not functioning properly. Check these when searching for sources of noise and vibration.
