15. Drive the vehicle in 4th or 5th gear with the shift

lever in S with the sequential sportshift mode, then
decelerate and downshift to 2nd gear by pressing
the paddle shifter

(downshift switch). The

vehicle should immediately begin to slow down
from the engine braking, then slow to a stop.

16. Shift to R, accelerate from a stop at full throttle

momentarily, and check for abnormal noise and
clutch slippage.

17. Park the vehicle on a slope (about 16-degrees),

apply the brake, and shift into P. Release the brake;
the vehicle should not move.

NOTE: Always use the brake to hold the vehicle,
when stopped on an incline in gear. Depending on
the grade of the incline, the vehicle could roll
backwards if the brake is released.

Automatic Transmission

Stall Speed Test

1. Make sure the transmission fluid is filled to the

proper level (see page 14-231).

2. Apply the parking brake, and block all four wheels.

3. Connect the HDS to the DLC (A) located under the

driver’s side of the dashboard.

4. Turn the ignition switch to ON (II), and go to the A/T

Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11-204).

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

6. Start the engine, and warm it up to normal

operating temperature (the radiator fan comes on).

7. Shift to D while pressing the brake pedal firmly,

then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.

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

S and R.

NOTE:

• Do not test the stall speed for more than

10 seconds at a time.

• The stall speed tests should be used for

diagnostic purposes only.

• Stall speed test results should be the same with

the shift lever in D, S, and R.

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

pressure gauges installed.

9. If the stall speeds are out of the service limit, the

problems and probable causes are listed in the
table.

• A/T pressure hose adapter 07MAJ-PY40120

NOTE:

• Disable the VSA by pressing the VSA OFF switch (if

equipped).

• VSA DTC(s) may come on during the pressure test. If

the VSA(s) come on, clear the DTC(s) with the HDS.

1. Make sure the transmission fluid is filled to the

proper level (see page 14-231).

2. Raise the vehicle on a lift, or apply the parking

brake, block rear wheels, and raise the front of the
vehicle. Make sure it is securely supported.

3. Remove the splash shield.

4. Allow the front wheels to rotate freely.

5. Connect the HDS to the DLC (A) located under the

driver’s side of the dashboard.

6. Turn the ignition switch to ON (II). Make sure the

HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).

7. Connect the A/T oil pressure gauge to the line

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

8. Start the engine, and warm it up to normal

operating temperature (the radiator fan comes on).

9. Measure the line pressure at the line pressure

inspection port with the shift lever in P or N while
holding the engine speed at 2,000 rpm.

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

11. Install the sealing bolt to the line pressure

inspection port with a new sealing washer, and
tighten the bolt to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do
not reuse the old sealing washer.

the air cleaner assembly (see page 11-345).

14. Remove the harness cover from its bracket, and

connect the A/T oil pressure gauge to the 2nd
clutch pressure inspection port (C). Then
temporarily install the air cleaner assembly and the
intake air duct.

15. Start the engine, and shift to S.

16. Shift to 1st gear by pressing the paddle shifter

(downshift switch) if needed, and measure the 1st
clutch pressure at the 1st clutch pressure
inspection port (B) while holding the engine speed
at 2,000 rpm.

17. Upshift to 2nd gear by pressing the paddle shifter

(upshift switch), and measure the 2nd clutch

pressure at the 2nd clutch pressure inspection port
(C) while holding the engine speed at 2,000 rpm.
