Transmission Fluid Inspection and
Replacement
'1. Park the vehicle on level ground, and turn the
engine OFF.
2. Remove the oilfiller plug (A) and washer (B), check
the condition of the fluid, and make sure the fluid is
at the proper level (C).
lf the transmission fluid is diny, remove the drain
plug (D) and drain the fluid.
A44 N.m{4.5 kgt.m,33 rbr.ftl
Reinstall the drain plug with a new washer, and
refill the transmission fluid to the proper level.
Oil Capacity
1.5 0 (1.6 US (F) at tluid change
1.7 0 {1.8 US qt) at overhaul
Always use Honda Manual Transmission Fluid
(MTF). Using motor oil can cause stiffer shifting
and noise because it does not contain the proper
additives.
Reinstall the oil filler plug with a new washer.5.

Back-Up Light Switch Test
1. Disconnectthe back-up light switch (A) connector.
Check for continuity between the back up light
swilch 2P connector No. 1 and No.2 terminals.
There should be continuity when the shift lever is in
reverse.
lf necessary, replace the back-up light switch.
Apply liquid gasket (P/N 08718-0001), and install it
on the transmission housing.

found, reDlace the boot and boot bands.
Turn the driveshaft by hand, and make sure the
splines (E) and joint are not excessively loose.
Make sure the driveshaft is not twisted or cracked;
if it is, replace it.
Driveshafts Removal
Special Tool Required
Balljoint remover, 28 mm 07MAC-S100200
1. Loosen the wheel nuts slightly
2. Raise the front of the vehicle, and support it with
safety stands in the proper locations (see page 1-8).
3. Remove the wheel nuts and front wheels.
4.Lift up the locking tab (A) on the spindle nut (B),
then remove the nut.
lf the !eft driveshaft or the intermediate shaft is to
be removed, drain the transmission fluid. Reinstall
the drain plug using a new washer (see page 13-3).
Hold the stabilizer balljoint pin (A) with a hex
wrench {B), and remove the flange nut (C).
Separate the front stabilizer link (D) from the lower
a rm.

9. Clean the mating surfaces ofthe brake disc and the
front wheel, then install the front wheel with the
wheel nuts.
10. Turn the front wheel by hand, and make sure the
clearance between the driveshaft and
circumference parts.
1 l. Refill the transmission with recommended
transmission fluid (see page 13-3).
12. Check the front wheel alignment, and adjust it if
necessary (see page 18-4).

Brake System Inspection and Tests
Brake System Test
Brake pedal sinks/fades when braking
1. Start the engine, and let it warm up to operating temperature.
2. Attach a 2-inch pieceof masking tape along the bottom of the steering wheel, and draw a horizontal reference
mark across it.
With the transmission in Neutral, press and hold the brake pedal lightly, then release the parking brake.
While still holding the brake pedal, hook the end of the tape measure behind it. Then pull the tape up to the
steering wheel, noting where the tape measure lines up with the reference mark you made on the masking tape.
Apply steady pressure to the brake pedal for 3 minutes.
Watch the tape measure.
. if it moves less than 10 mm, the master cylinder is OK.
. if it moves more than 10 mm replace the master cylinder.
