Evaluation of stall test
Above specification
Below specification
Time Lag Test
1. Perform mechanical system test preparation. (See
2. Use a stopwatch to measure the time it takes from shifting until shock is felt when shifting the selector lever
from N position to D range (non-HOLD mode). Take three measurements for each test and take the average
from the results using the following formula.
Formula:
Average time lag = (Time 1 + Time 2 + Time 3) / 3
3. Perform the test for the following shifts in the same manner Step 2.
• N position → D range (HOLD mode)
• N position → R position
Time lag
N position → D range ... 0.4—0.7 s
N position → R position ... 0.4—0.7 s
Evaluation of time lag test
N → D shift
N → D (HOLD) shift
N → R shift
