1. Remove the fuel tank unit (see page 11-334).
2. Remove the bracket (A).
3. Remove the ground ring (B).
4. Remove the fuel pressure regulator (C).
5. Install the parts in the reverse order of removal with new O-rings (D) and a new bracket (A). When
installing the fuel tank unit, align the marks on the
unit and the fuel tank (see page 11-335).
NOTE: Coat the O-rings with clean engine oil; do
not use any other oil.
Do not pinch the O-rings during installation. The fuel filter should be replaced when
ever the fuel
pressure drops below the specified value (see page
11-325), after making sure that the fuel pump and the
fuel pressure regulator are OK.
1. Remove the fuel tank unit (see page 11-334).
2. Remove the fuel filter set (A).
3. Check these items before installing the fuel tank unit:
 When connecting the wire harness, make sure the connection is secure and the connectors (B)
are firmly locked into place.
 When installing the fuel gauge sending unit (C), make sure the connection is secure and the
connector is firmly locked into place. Be careful
not to bend or twist it excessively.

7. Inspect for warpage using a straight edge (A) and a feeler gauge (B). Measure across the pressure plate
surface (C). If the most measurement difference is
more than the service limit, replace the pressure
plate. 8. Remove the clutch disc (A), the clutch alignment
shaft (B), and the remover handle (C).
9. Inspect the lining of the clutch disc for signs of slipping or oil. If the clutch disc looks burnt or is
soaked with oil, replace it and the pressure plate as
a set. If the clutch disc is oil soaked, find and repair
the source of the oil leak.
10. Measure the clutch disc thickness. If the measurement is less than the service limit, replace
the clutch disc.

11. Zero a dial gauge (A) on the end of the mainshaft.
12. Turn the catch adapter bolt (B) clockwise; stop
turning when the dial gauge has reached its
maximum movement. The reading on the dial
gauge is the amount of mainshaft thrust clearance.
NOTE: Do not turn the catch adapter bolt exceeds
60 degrees after the needle of the dial gauge stops
moving. Applying more pressure with the catch
adapter bolt could damage the transmission.
13. If the reading is within the standard, the clearance is correct. If the reading is not within the standard,
select the appropriate shim needed from the table,
and recheck the thrust clearance.
Subtract the total clearance measurement from the
middle of the clearance standard 0.14 mm
(0.0056 in.)
Select the shim closest to the amount calculated.
For this example, the 1.80 mm (0.071 in.) shim is
best.
14. With oil guide plate M and the appropriate size shim installed in the transmission housing, check
the thrust clearance again to make sure the
clearance is within the standard. A 23931-P21-000 0.60 mm (0.024 in.)

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 SandR.
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.

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.
Line 900 960 kPa (9.2 9.8 kgf/cm ,
130 140 psi) 850 kPa
(8.7 kgf/cm ,
120 psi)
10. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection
port.
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.

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
