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 first 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: 650 ± 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 from when the lever is shifted until the shock is felt.
Time lag: N -> D Less than 1.2 seconds
- In the same manner, measure the time lag for N -> R.
Time lag: N -> R Less than 1.5 seconds
EVALUATION
If N -> D or N -> R time lag is longer than specified:
