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 U/D direct clutch, forward clutch, direct clutch, and 1st and reverse brake.
NOTICE:
- Do the test at normal operating fluid temp. 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 N position and A/C OFF)
- Shift the shift lever from the N to 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 is longer than specified:
