a. D position test:
Shift into the D position and fully depress the accelerator pedal and check the following points.
1. Check up-shift operation.
Check that 1 --> 2,2 --> 3,3 --> 4,4 --> 5 and 5 --> 6th up-shifts take place, and that the shift
points conform to the automatic shift schedule (see SERVICE DATA
).

2. Check for shift shock and slip.
Check for shock and slip at the 1 --> 2,2 --> 3, 3 --> 4, 4 --> 5 and 5 --> 6th up-shifts.
3. Check for abnormal noise and vibration.
Check for abnormal noise and vibration when up-shifting from 1 --> 2, 2 --> 3, 3 --> 4, 4 -->
5 and 5 --> 6 while driving with the shift lever in the D position, and also check while driving
in the lock-up condition.
HINT:
The check for the cause of abnormal noise and vibration must be done thoroughly as it could
also be due to loss of balance in the differential, torque converter clutch, etc.
4. Check kick-down operation.

kick-downs take place while driving with the shift lever in the D position. Confirm that each
speed is within the applicable vehicle speed range indicated in the automatic shift schedule
(see SERVICE DATA
).
5. Check for abnormal shock and slip at kic
k-down.
