TIME LAG TEST

before the shock can be felt. This is used for checking the condition of the 4/D direct clutch,
forward clutch, direct clutch, and first and reverse brake.
NOTICE:
Perform the test at normal operating fluid temperature 50–80 _C (122–176 _F).
Be sure to allow a one minute Interval between tests.
Make 3 measurements and take the average value.
