Final Check

STALL TESTING

STALL TEST PROCEDURE




1. Check A/T and engine fluid levels. If necessary, add.
2. Warm up engine until engine oil and A.T.F. reach operating temperature after vehicle has been driven approx. 10 minutes.

A.T.F. operating temperature: 50 - 80°C (122 - 176°F)




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 put a mark on point of specified engine rpm on Indicator.



5. Start engine, apply foot brake, and place selector lever in "D" range.




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.

Stall revolution: 1,950 - 2,250 rpm




8. Shift selector lever to "N".
9. Cool off A.T.F.
Run engine at idle for at least one minute.
10. Perform stall tests in the same manner as in steps 5 through 9 with selector lever in "1" and "R", respectively.

Judgement Of Stall Test:

JUDGEMENT OF STALL TEST
If converter one-way clutch is frozen, vehicle will have poor high-speed performance and low engine rpm when it is raced in "N" range. If converter one-way clutch is slipping, vehicle will be sluggish up to 50 or 60 KPH (30 or 40 MPH).

PRESSURE TESTING




- Location of line pressure test port
- Always replace line pressure plugs as they are self-sealing bolts.

Line pressure test procedure




1. Check A/T and engine fluid levels. If necessary, add.
2. Warm up engine until engine oil and A.T.F. reach operating temperature after vehicle has been driven approx. 10 minutes.

A.T.F. operating temperature: 50 - 80°C (122 - 176°F)




3. Install pressure gauge to line pressure port.




4. Set parking brake and block wheels.
- Continue to depress brake pedal fully while line pressure test at stall speed Is performed.




5. Start engine and measure line pressure at idle and stall speed.
- When measuring line pressure at stall speed, follow the stall test procedure.

LOCK-UP TEST







Install pressure gauge to lock-up pressure port. Shift selector lever in "D" range.
If lock-up pressure is not within specifications, refer to Diagnostic Procedures 15 and 16. Diagnostic Procedure 15 Diagnostic Procedure 16
