MaintenanceBack-up Light Switch
Transmission Oil
NOTE: Check the transmission oil with the engine OFF
and the vehicle on level ground.
1. Remove the oil filler plug, then check the level and
condition of the oil.

4.
WASHERReplace.
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 with a new washer.
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 with the recommended oil to the
proper lever.
NOTE: The drain plug washer should be replaced at
every oil change.
Reinstall the oil filler plug with a new washer.

Always use Genuine Honda Manual Transmission
Fluid {MTF). Using motor oil can cause stiffer shift-
ing because it does not contain the proper addi-
t|ves.

solenoid valve A,/B assemblv.
SHIFT CONTROLSOLENOID VALVE A/B
ASSEMBLY
N4easure the resistance between the No. 1 terminal(solenoid valve A) of the shift control solenoid valve
connector and body ground, and between the No. 2
terminal (solenoid valve B) and body ground.
STANDARD: 12 - 25 O
Replace the shift control solenoid valve assembly if
the resistance is out of specification,
lf the resistance is within the standard, connect the
No. 1 te.minal of the shift control solenoid valve
connector to the battery positive terminal. A clicking
sound should be heard. Connect the No. 2 terminal
to the battery positive terminal. A clicking sound
should be heard. Replace the shift control solenoid
valve assembly if no clicking sound is heard.

Replacement
NOTE: Shift control solenoid valves A and B must be
removed/replaced as an assembly.
1. Remove the mounting bolts and shift control solenoid
valve A,/B assembly.

Clean the mounting surface and fluid passages of
the shift control solenoid valve assembly, and
install a new shift control solenoid valve Ay'B with a

Check the connector for rust. dirt or oil. and recon-
nect it securelv,

Road Test
NOTE: Warm up the engine to normal operating tem peratu re (the rad iator fan comes on )'
1. Apply parking brake and block the wheels. Start the engine, then shift to E position while depressing the brake
Dedal, Depress the accelerator pedal and release it suddenly. The engine should not stall'
2. Repeat same test in E Position.
3. Test-drive the vehicle on a flat road in the E position. Check that the shift points occur at approximate speeds shown
in the table. Also check for abnormal noise and clutch slippage.
NOTE: Throttle position sensor voltage represents the throttle opening
a. Unbolt the PCM for road testing; refer to page 14-50.
b. Setthedigital multimeter to check the th rottle position sensor voltage between PCM terminals;
