Transmission Fluid, Brake and Clutch Fluid
5-speed Manual Transmission
FILLER BOLT
Correct level
Check the fluid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground. Remove the
transmission filler bolt and carefully
feel inside the bolt hole with your
finger. The fluid level should be up
to the edge of the bolt hole. If it is
not, add Genuine Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the hole. Reinstall
the filler bolt and tighten it securely.
Maintenance
If Honda M T F is not available, you
may use an API service SG, SH or SJ
grade motor oil with a viscosity of
SAE 10W-30 or 10W-40 as a
temporary replacement. An SG
grade is preferred, but an SH or SJ
grade may be used if SG is not
available. However, motor oil does
not contain the proper additives and
continued use can cause stiffer
shifting. Replace as soon as
convenient.
The transmission should be drained
and refilled with new fluid according
to the time and distance recommen-
dations in the maintenance schedule.
Brake and Clutch Fluid
Check the fluid level in the reser-
voirs monthly. There are one or two
reservoirs, depending on model.
They are:
Brake fluid reservoir (all models)
Clutch fluid reservoir
(manual transmission only)
The brake fluid in the brake system
should be replaced according to the
time and distance recommendations
in the maintenance schedule.
