Time Lag Test

TIME LAG TEST

When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before the shock can be felt. This is used for checking the condition of the O/D direct clutch,forward clutch, direct clutch, and 1st and reverse brake.

NOTICE:
- Do the test at normal operating fluid temperature 50 - 80°C (122 - 176°F).
- Be sure to allow 1 minute interval between tests.
- Take three measurements and take the average value.

MEASURE TIME LAG
- Fully apply the parking brake
- Start the engine and check idle speed.

Idle speed: 700 ± 50 rpm (In the N position and A/C OFF)

- Shift the shift lever from the N to the D position. Using a stop watch, measure the time it takes from shifting the lever until the shock is felt.
- In same way. measure the time lag for N R.

Time lag:
N -> D Less than 1.2 seconds
N -> R Less than 1.5 seconds





EVALUATION

If N -> D or N -> R time lag are longer than specified
