Repair
NOTE: This repair is only necessary if one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to free the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may b€ necessary to use a small
screwdriver to pry the valve free. Be careful not to
scratch the bore whh the screwdriver.
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 a ir.
Roll up half a sheet of ATF-soaked 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.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burrs,

Remove the #600 paper and thoroughly wash the
entire valve body in solvent. then dry it with com-
pressed air.
Coat the valve with ATF, then drop ir into its bore.
It should drop to the bonom of the bore under its
own weight. lf not, repeat step 4, then retest.
VALVE BODY
Remove the valve. then thoroughly clean it and the
valve body with solvent. Dry all parts with com-
pressed air. then reassemble using ATF as a lubri
cant.

Description
Park Mechanism
The park mechanism locks the transmission by engaging the park pawl with the park gear which is integral with the sec-ondary drive gear' The secondary drive gear engages with the secondary driven gear which engages wit-h the final drivengear.
shifting to E position causes the park cone (installed at the end of the park rod) to press the park pawl onto the park gear.Even if the end of the park pawl rides on the top of the park gear teeth, slight movement of the vehicle will cause the parkpawl and the park gear to mesh with each other completely because the park cone receives the tension from the park rodspring The park pawl receives the tension (which acts to separate the park pawl from the park gear) from the park pawlspring.

Troubleshooting Procedures
l. How To Begin Troubleshooting
When the E indicator light has been reported on, use the appropriate procedure below to diagnose and repatr theproDlem.
A. When the @ indicator light has come on:
l connect the Honda PGM Tester or an oBD ll Scan Tool to the 16P Data Link Connector (DLc) located near the leftkick panel.
Turn the ignition switch ON (ll).
Check the DTC and note it. Also check and notethe freeze frame data.
Refer to the Diagnostic Trouble Code Chart andbegin troubleshooting.
INOICATORLIGHT
NOTE: SeetheOBDll Scan Tool or Honda PGM Tester user's manuals for specific operating instructions.
Some PGM-FI problems will also make the E indicator light come on. After repairing the pGM-Fl system, disconnect theBACK UP fuse (7.5 Al in the under-hood fuse/relay box for more than l0 seconds to reset the TCM or PCM memory, rnenrecheck.
NOTE: Disconnecting the BACK UP fuse also cancels the radio preset stations and the clock setting. Make note of theradio presets before removing the fuse so you can reset them,
