CONVERTER STALL TEST
In this test,the engine maximum speed when the
torque converter stallswith the shift lever in the
DorR
range is measured to check operation
ofthetorqueconverter;starterandone-way
clutch and check hlding performance of the trans-
mission clutch (including brake)
Caution
Do not stand in front or at rear of the vehicle
duringthis test:
(1) Check the transmission fluidlevel:Thefluid
temperature shouldbe at the level after nor-
mal operation [70-80*C (158-1769F)]. The en-
gine coolant temperature should also be at the
level afternormal operation [80-908C(176 _
194PF)] .

3) Mount an engine tachometer.
Apply fully the parking and service brakes
Start the engine.
(6)With the selector lever in the "Drange , fully
depress the accelerator pedal and read off the
enginemaximum speed,
Standard value:2,100-2,400 r/min <V4AWZ> 2,100-2,600 rImin: <V4AW3>
NOTE

necessaryduration(5 secondsormore)If
two or more stall tests are needed, place the
selector lever in theNposition and run the
engine at about 1,000 r/min to allow the trans-
mission fluid to cool before another stall test
Place the selector lever in the"R" range and
perform the test as above_

| Stall speed in D range is equal to each and other but lower than the nominal value. | Engine output is low Starter one-way clutch is faulty. (Faulty torque converter is suspected if it is lower than nominal by more than 600 rlmin ) |
|---|---|
| "D" range is higher than nominal: Stall speed in | O.D. clutch slipping one-way clutch faulty O.D. (3) Forward clutch slipping (4) One-way clutch No. 2 faulty (5) Low line pressure |
| Stall speed in range is higher than nominal. "R | (1) O.D. clutch slipping (2) O.D. one-way clutch faulty (3) Direct clutch slipping Brake No. 3 slipping (5) Low line pressure |
