Final Check

STALL TESTING

Stall test procedure
1. Check A/T and engine fluid levels. If necessary, add.
2. Drive vehicle for about 10 minutes until engine oil and ATF reach operating temperature.

ATF 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 speed 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.

Stall revolution:
2,450 - 2,650 rpm (RE4R01A)
2,950 - 3,200 rpm (RE4R03A)

8. Shift selector lever to "N".
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" positions.

JUDGEMENT OF STALL TEST
The test result and possible damaged components relating to each result are shown in the illustration.

NOTE:
Stall revolution is too high in "D" or "2" position:
- Slippage occurs in 1st gear but not in 2nd and 3rd gears - Low one-way clutch slippage
- Slippage occurs in the following cases:
1. 1st through 3rd gears in "D" position and engine brake functions with power shift switch set to "POWER".
2. 1st and 2nd gears in "2" position and engine brake functions with accelerator pedal completely released (fully closed throttle) - Forward clutch or forward one-way clutch slippage

Stall revolution is too high in "R" position:
- Engine brake does not function in "1" position - Low & reverse brake slippage
- Engine brake functions in "1" position - Reverse clutch slippage

Stall revolution within specifications:
- Vehicle does not achieve speed of more than 80 KPH (50 MPH) - One-way clutch seizure in torque converter housing

CAUTION:
Be careful since automatic fluid temperature increases abnormally.
- Slippage occurs in 3rd and 4th gears in "D" position - High clutch slippage
- Slippage occurs in 2nd and 4th gear in "D" position - Brake band slippage

Stall revolution less than specifications:
- Poor acceleration during starts - One-way clutch seizure in torque converter










PRESSURE TESTING
- Location of line pressure test port
- Line pressure plugs are hexagon headed bolts.
- 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. Drive vehicle for about 10 minutes until engine oil and ATF reach operating temperature.

ATF operating temperature: 50 - 80 °C (122 - 176 °F)

3. Install pressure gauge to line pressure port.

- D, 2 and 1 positions -




- R position -




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

Line Pressure:

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