Evaluation:
(a) Stall speed low in D and R positions
(b) Stall speed high in D position
(c) Stall speed high in R position
(d) Stall speed high in D and R positions
(b) Measure the time lag.
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 1st and reverse brake.
NOTICE:
Do the test at normal operating fluid temperature 50 − 80°C (122 − 176°F)
S
Be sure to allow 1 minute interval between tests.
S
Take 3 measurements and take the average value.
S
(1) Fully apply the parking brake.
(2) Start the engine and check idle speed.
Idle speed (In N position and air conditioner OFF):
3RZ−FE: 700 ± 50 rpm
5VZ−FE: 700 ± 50 rpm
(3) 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.
In the same manner, 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 time or N → R time lag is longer than specified):
N → D time lag is longer
N → R time lag is longer
