Stall TestECS004VS
STALL TEST PROCEDURE
1. Check A/T fluid and engine oil levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes or until fluid and oil reach
operating temperature. Refer to AT- 1 7 , "
Changing A/T Fluid" .
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in D
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately release
throttle.

During test, never hold throttle wide open for more than 5
seconds.
8. Move selector lever to N position.
9. Cool off ATF.

Run engine at idle for at least one minute.
10. Repeat steps 5 through 9 with selector lever in 2, 1 and R posi-
tions.

LINE PRESSURE TEST PORTS
Location of line pressure test ports are shown in the illustration.

Always replace pressure plugs as they are self-sealing
bolts.
LINE PRESSURE TEST PROCEDURE
1. Check A/T fluid and engine oil levels. If necessary, add fluid or
oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature. Refer to AT- 1 7 , "
Changing A/T
Fluid" .
3. Install pressure gauge to corresponding line pressure port.
4. Set parking brake and block wheels.

Continue to depress brake pedal fully while line pressure
test is being performed at stall speed.
