The oil level must be up to the filler hole. lf it is
below the hole, add oil until it runs out, then rein-
stall the oil filler plug.
lf the transmission oil is dirty, remove the drain plug
and drain the oil.
Reinstall the drain plug with a new washer. and refill
the transmission oil to the proper level.
NOTE: The drain plug washer should be replaced at
every oil change.
Reinstallthe oilfiller plug with a new washer.

Always use Genuine Honda Manual Transmission
Fluid (MTF). Using motor oil can cause stiffer shift-

Description
(cont'dl
Gear Selection
The shift lever has six positions: E PARK. E REVERSE, N NEUTRAL, E 1st through 4th gear ranges, E 1st through 3rdgear ranges, @ 2nd gear.
Starting is possible only in E and E positions through the use of a slide-type, neutral-safety switch.
Automatic Transaxle (A/f, Gear Position Indicator
The Ay'T gear position indicator in the instrument panel shows which gear has been selected without having to look downat the console.
Clutch€s
The four-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears.When hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs andsteel plates together, locking them so they don't slip. Power is then transmitted through the engaged clutch pack to itshub-mounted gear. Likewise, when the hydraulic pressure is bled from the clutch pack, the piston releases the friction discsand the steel plates, and they are free to slide past each other. This allows the gear to spin independently on its shaft,transmitting no power.
lst Clutch
The 1st clutch engages/disengages 1st gear, and is located at the end of the mainshaft, just behind the right sroe cover.The 1st clutch is supplied hydraulic pressure by its ATF feed pipe within the mainshaft.
2nd Clulch
The 2nd clutch engagegdisengages 2nd gear, and is located at the middle of the mainshaft. The 2nd clutch is joined
back-to-back to the 4th clutch. The 2nd clutch is supplied hydraulic pressure through the mainshaft by a circutr connect-ed to the internal hvdraulic circuit,
3rd Clutch
The 3rd clutch engages/disengages 3rd gear, and is located at the end of the countershaft. The 3rd clutch is suooliedhydraulic pressure by its ATF feed pipe within the countershaft.
ilth Clutch
The 4th clutch engages/disengages 4th gear, as well as reverse gear, and is located at the middle of the mainshaft. The4th clutch is joined back-to-back to the 2nd clutch. The 4th clutch is supplied hydraulic pressure by its ATF feed pipewith in the mainshaft.

@ Position
As the engine turns, the ATF pump also starts to operate, Automatic transmission fluid (ATF) is drawn from (99) and dis-
charged into (1). Then, ATF flowing from the ATF pump becomes the line pressure (1). The line pressure (1) is regulated
by the regulator valve. The torque conv€rter inlet pressure (92) enters (94) of the torque converter through the lock-up
shift valve and discharges into (901. The torque converter ch€ck valve prevents the torque converter pressure from rising'
Under this condition, the hydraulic pressure is not applied to the clutches'
NOTE: When used, "1eft" or "right" indicates direction on the hydraulic circuit'

PCM Reset Procedure
1. Turn the ignition switch off.
2. Remove the BACK UP fuse (7.5 A) from the under-hood fuse/relay box for '10 seconds to reset the PCM'
NOTE:
. Disconnecting the BACK UP fuse also cancels the radio preset stations and clock setting Make note of the radio
presets before removing the luse so you can reset them
. in" gCfU memory can also be cleared by using the OBD ll Scan Tool or Honda PGM Tester'
Final Procedure
NOTE: This procedure must be done after any troubleshooting.
1. Turn the ignition switch OFF.
2. Reset the PcM.
3. Disconnect the oBD ll scan Tool or Honda PGM Tester from the Data Link connector, or remove the special tool from
the Service Check Connector.
4. Turn the ignition switch ON (ll), and set the radio presets and clock setting'
