N position with the 2.0 mm (0.08 in.) blade (C).
8. Tighten the bolts on the transmission range switch while you continue to holding the N position. Do
not move the transmission range switch when
tightening the bolts. Remove the feeler gauge. 9. Check the connectors for rust, dirt, or oil, clean or
repair if necessary, then connect the connector
securely.
10. Turn the ignition switch to ON (II). Move the shift lever through all positions, and check the
transmission range switch synchronization with the
A/T gear position indicator.
11. Check that the engine will start with the shift lever in P and N, and will not start in any other shift lever
position.
12. Check that the back-up lights come on when the shift lever is in R.
13. Allow the front wheels to rotate freely, then start the engine, and check the shift lever operation.
14. Install the transmission range switch cover (A).

16. Monitor the Brake Switch in the Data List with the
HDS, and press the brake pedal.
Go to step 21.
If the brake lights come on, go to step 17. If
the brake lights do not work, repair the faulty brake
light circuit.
17. Turn the ignition switch to LOCK (0).
18. Jump the SCS line with the HDS.
19. Disconnect PCM connector A (44P). 20. Measure the voltage between PCM connector
terminal A40 and body ground when pressing the
brake pedal and when the brake pedal is released.
Reconnect all connectors, then update the
PCM if it does not have the latest software
(see page 11-227), or substitute a known- good PCM
(see page 11-7), then recheck. If the symptom goes
away with a known-good PCM, replace the original
PCM (see page 11-228).
Repair open in the wire between PCM
connector terminal A40 and the brake pedal
position switch.
21. Monitor the A/T P Switch in the Data List with the HDS with the shift lever in P.
Go to step 33.
Go to step 22.

9. Shift the shift lever to P.
10. Check for continuity between park pin switch/A/T gear position indicator panel light connector
terminals No. 3 and No. 4. Do not push the shift
lever button.
Faulty park pin switch, replace the park pin
switch (see page 14-269).
Go to step 11. 11. Disconnect under-dash fuse/relay box connector F
(34P).
12. Turn the ignition switch to ON (II).
13. Measure the voltage between the No. 27 terminal of under-dash fuse/relay box connector F (34P) and
body ground.
Substitute a known-good MICU, and
recheck.
Repair or short in the wire between PCM
connector terminal B13, transmission range switch,

Park Pin Switch Test
6. Apply silicone grease to the pin on the shift lever bracket base, and install the shift lock stop over the
pin.
7. Install the shift lock release spring and the shift lock release, apply silicone grease to shift lock release
mounting tip if necessary.
8. Apply silicone grease to the tip of the shift lock stop, and install the shift lock solenoid assembly by
aligning the joint of the shift lock solenoid plunger
with the tip of the shift lock stop.
9. Route the shift lock solenoid harness in the guide.
10. Install the shift lever assembly (see page 14-255). 1. Remove the center console (see page 20-92).
2. Move the shift lever to P, and check for continuity
between park pin switch/A/T gear position indicator
panel light connector terminals No. 3 and No. 4.
There should be no continuity.
3. Shift out of P, and check for continuity between connector terminals No. 3 and No. 4.
There should be continuity.
4. If the park pin switch tests OK, install the center console (see page 20-92).
If the park pin switch fails the test, replace the park
pin switch (see page 14-269).

Valve Body Repair
B A
6. Remove the cooler check valve spring (L) and thecooler check valve (M), then remove the main valve
body (N) (three bolts). Do not let the check balls (O)
fall out.
7. Remove the ATF pump driven gear shaft (P), then remove the ATF pump gears (Q).
8. Remove the main separator plate (R) and the two dowel pins (S).
9. Remove the ATF magnet (T), clean and reinstall it in the torque converter housing (U).
10. Clean the inlet opening (A) of the ATF strainer (B) thoroughly with compressed air, then check that it
is in good condition and that the inlet opening is
not clogged.
11. Test the ATF strainer by pouring clean ATF through the inlet opening, and replace it if it is clogged or
damaged.
12. Remove the O-rings (V) (W) from the stator shaft and the ATF strainer. Install the new ones when
installing the valve bodies. NOTE: This repair is only necessary if one or more of
the valves in a valve body do not slide smoothly in their
bores. Use this procedure to free the valves.
1. Soak a sheet of 600 abrasive paper in ATF for about 30 minutes.
2. Carefully tap the valve body so the sticking valve drops out of its bore. It may be necessary to use a
small screwdriver to pry the valve free. Be careful
not to scratch the bore with the screwdriver.
3. Inspect the valve for any scuff marks. Use the ATF- soaked 600 paper to polish off any burrs that are
on the valve, then wash the valve in solvent and
dry it with compressed air.
4. Roll up half a sheet of ATF-soaked 600 paper and insert it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly, then polish the bore by twisting the
paper as you push it in and out.
NOTE: The valve body is aluminum and does not
require much polishing to remove any burrs.
