Time Lag Test

Time Lag Test





If the shift lever is shifted while the engine is idling, there will be a certain time elapse or lag before the shock can be felt. This is used for checking the condition of the forward clutch, direct clutch, No.3 brake, and No.2 one-way clutch.

NOTE:
1. Perform the test at normal operation fluid temperature (50 - 80°C or 122 - 176°F)
2. Be sure to allow one minute interval between tests.
3. Make three measurements and take the average value.
