Road Test (cont’d)

9. Test-drive the vehicle on a flat road in the D4

position. Check for abnormal noise and clutch
slippage. While driving, check that the shift points
occur at the proper speeds by monitoring the
throttle position sensor voltage and comparing
your shift point speeds and voltage to those in the
table. (The throttle position sensor voltage
represents the throttle opening.)

10. Accelerate to about 35 mph (57 km/h) so the

transmission is in 4th or 5th, then shift from the D4
position to the 2 position. The vehicle should
immediately begin slowing down from engine
braking.

11. Check for abnormal noise and clutch slippage in

the following positions.

1 (1st Gear) Position
Accelerate from a stop at full throttle. Check that
there is no abnormal noise or clutch slippage.
Upshifts should not occur with the shift lever in this
position.

2 (2nd Gear) Position
Accelerate from a stop at full throttle. Check that
there is no abnormal noise or clutch slippage.
Upshifts and downshifts should not occur with the
shift lever in this position.

R (Reverse) Position
Accelerate from a stop at full throttle, and check for
abnormal noise and clutch slippage.

12. Test in P (Park) Position.

Park the vehicle on a slope (about 16°), apply the
brake, and shift into the P position. Release the
brake; the vehicle should not move.

Stall Speed Test

1. Engage the parking brake, and block all four wheels.

2. Connect a tachometer to the engine, and start the

engine.

3. Make sure the A/C switch is OFF.

4. After the engine has warmed up to normal

operating temperature (the radiator fan comes on),
shift to the 2 position.

5. Fully press the brake pedal and accelerator pedal

for 6 to 8 seconds, and note the engine speed. Do
not move the shift lever while raising the engine
speed.

6. Allow 2 minutes for cooling, then repeat the test in

the D4, 1, and R positions.

NOTE:

• Do not test stall speed for more than 10 seconds

at a time.

• Stall speed tests should be used for diagnostic

purposes only.

• Stall speed should be the same in D4, 2, 1, and R

positions.

• Do not test stall speed with the A/T pressure

gauges installed.

7. If the measurements are out of the service limit,

problems and probable causes are listed in the
table below:

•
•

1. Before testing, be sure the transmission fluid is

filled to the proper level.

2. Raise the vehicle, and make sure it is securely

supported.

3. Allow all four wheels to rotate freely.

4. Warm up the engine (the radiator fan comes on),

then stop it and connect a tachometer.

5. Connect the oil pressure gauges to the line

pressure inspection hole (A). Do not allow dust or
other foreign particles to enter the holes while
connecting the gauges.

6. Connect the oil pressure gauges to the 1st clutch

pressure inspection hole (B), 3rd clutch pressure
inspection hole (D), and 4th clutch pressure
inspection hole (E).

7. Connect the oil pressure gauge to the 2nd clutch

pressure inspection hole (C).

8. Start the engine, and run it at 2,000 rpm in the N or

P position.

9. Measure line pressure at the line pressure

inspection hole (A) in the N or P position.

NOTE: Higher pressure may be indicated if
measurements are made in shift lever position
other than N or P.

10. Shift to the 1 position, and measure 1st clutch

pressure at the 1st clutch pressure inspection hole
(B).

11. Shift to the 2 position, and measure 2nd clutch

pressure at the 2nd clutch pressure inspection hole
(B).

12. Shift to the P position, then press the brake pedal

and hold it.

13. Shift to the D4 position, and release the brake pedal

(the transmission should be in 1st gear).

14. Accelerate the engine to 2,500 rpm (the

transmission will shift to 2nd gear).

15. Release the accelerator for more than 5 seconds

after the transmission is shifted to 2nd gear (the
engine will come down to about 1,000 rpm).

16. Press the accelerator very slowly to increase

engine speed to 2,000 rpm gradually over 5
seconds, then hold it at 2,000 rpm.

17. Measure 3rd and 4th clutch pressure at 3rd clutch

pressure inspection hole (D), and 4th clutch
pressure inspection hole (E) (the transmission will
shift from 2nd gear to 3rd gear, and then 4th gear).

18. Bring the engine back to an idle, then apply the

brake to stop the wheels from rotating.

19. Shift to the R position. Raise the engine rpm to

2,000 rpm, and measure 4th clutch pressure at the
4th clutch pressure inspection hole (E).
