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.

Synchro Ring and Gear Inspection (cont'dl
3. Inspect the thrust surface {D) on each gear hub for
wear.
Inspect the cone surface (E) on each gear hub for
wear ano rougnness.
Inspect the teeth on all gears (F) for uneven wear,
scoring, galling, and cracks.
Coat the cone surface of each gear (E) with oil, andplace its synchro ring on it. Rotate the synchro ring,
making sure that it does not slip.

7. Measure the clearance between each gear (A) and
its synchro ring (B) allthe way around. Hold the
synchro ring against the gear evenly while
measuring the clearance. lf the clearance is less
than the service limit, replace the synchro ring andgear.
