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 1st and reverse brake.
NOTICE:
- Perform this 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 the N position and air conditioning 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.
Time lag: N -> D Less than 1.2 seconds
- In same way, 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:
