(6) Shift it into the D position. Press all the way down on the accelerator pedal with your right foot. Quickly read the stall speed at this time.

(7) Do the same test in the R position. Stall speed: 2,300 ± 200 rpm EVALUATION

Problem

Possible cause

(a) Stall speed low in D and R positions.

CEngine output may be insufficient

CStator one-way clutch is not operating properly

(b) Stall speed high in D position.

CLine pressure too low

CForward clutch slipping

CNo.2 one-way clutch not operating properly

(c) Stall speed high in R position.

CLine pressure too low CDirect clutch slipping Olst and reverse brake slipping

(d) Stall speed high in D and R positions.

4. MEASURE TIME LAG TEST

When 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 and 1st and reverse brake. NOTICE:

O Do the test at normal operating fluid temperature 50 - 80 °C (122 - 176°F). O Make sure to allow 1 minute interval tests. O Make 3 measurements and take the average value.

(1) Fully apply the parking brake.

(2) Start the engine and check the idle speed.

Idling speed: 750 ± 50 rpm (In N position and A/C OFF)

(3) Shift the shift lever from the N to D position. Using a stop watch, measure the time it takes from shifting the lever to the shock is felt.

Time lag: Less than 1.2 seconds

(4) In the same way, measure the time lag for N ^ R. Time lag: Less than 1.5 seconds

EVALUATION (If N ^ D time lag are longer than than specified):

Problem

Possible cause

N ^ D time lag is longer

CLine pressure too low CForward clutch worn CDirect clutch worn C1st and reverse brake worn
