Time Lag Test
TIME LAG TESTWhen 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 first and reverse brake.
NOTICE:
- Do the test at normal operating fluid temperature 50 - 80 °C (122 - 176 °F).
- Be sure to allow a one minute interval between tests.
- Take 3 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 N position and air conditioner OFF)
- Shift the shift lever from N to D position. Using a stop watch, measure the time it takes from shifting the lever until the shock is felt.
- In same manner, 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:
