Fluid Level
l.Checking/Changing
CAUTION: while chscking and changing, be sure not to
allow dust and other toreign particles to ent€l inlo the
transmission.
Checking
NOTE: Check the fluid level with the engine at normal
operating temperature (the radiator fan comes on).
'1. Park the vehicle on the level ground. Turn oft the
engrne.
2. Remove the dipstick (yellow loop) from the trans-
mission, and wipe lt with a clean cloth.
NOTE: Check the transmission fluid 50 to 90 sec-
onds after shutting off the engine.
3. Insert the diDstick into the transmission.
DIPSTICK (YELLOW LOOPI
Remove the dipstick and check the fluid level.
should be between the uDDer and lower mark.DIPSTICK
5. lf the level is below the lower mark, add fluid into
the filler hole to bring it to the upper mark. Use
Genuine Honda CW Fluid only.
6. Insert the dipstick into the transmission.
14-299
Changing
1. Bring the transmission up to normal operating tem-
perature (the radiator fan comes on) by driving the
vehicle. Park the vehicle on the level ground, and
turn off the engine.
2. Bemove the drain plug, and drain the CVT fluid.
NOTE| lf a cooler flusher is to be used, see page 14-
352 and 14-353.
Reinstall the drain plug with a new sealing washer,
then refill the transmission with Genuine Honda
CVT Fluid to the upper mark on the dipstick.

Gooler Flushing
@ To prevent iniury to face and eyes, alwayswear safety glasses or a tace shield when using thetransmission flusher.
NOTE: This procedure should be performed before rein-stalling the transmission.
'1. Check the tools and hoses for wear and cracks before
using. lf wear or cracks are found, reDlace the hoses
before using.
4.
Using the measuring cup. fill the tank with 2,1 ounces(approximately 2/3 full) of biodegradable flushingfluid (J35944 - 20). Do not substitute with any otherfluid. Follow the handling procedure on the fluidcontatner.
Secure the flusher filler cap, and pressurize the tankwith compressed air to between 5S0 - 829 kpa (5.6 -
8.45 kgf/cm', 80 - 120 psi).
NOTE: The air line should be equipped with a watertrap to ensure a dry air system,
Hang the tool under the vehicle.
Attach the tank's discharge hose to the return lineoi the transmission cooler using a clamp.
Connect the drain hose to the inlet line on the trans-mission cooler using a clamp.
IMPORTANT:
Securely clamp the opposite end ofthe drain hose to abucket or floor drain,

7. With the water and air valves off, attach the water andair supplies to the flusher. (Hot water if available.)
8. Turn on the flusher water valve so water will flowthrough the cooler for 10 seconds.
NOTE: lf water does not flow through the cooler, itis completely plugged, cannot be flushed, and mustbe replsced.
9. Depress the trigger to mix the flushing fluid into thewater flow. Use the wire clip to hold the trigger down.
'10. While flushing with the water and flushing fluid fortwo minutes. turn the air valve on for five secondsevery 15 - 20 seconds to create a surging action.AIR PRESSURE: MAX 845 kpa (8.45 kgflcmr, 120 psi)
11. Turn the water valve off. Release the trigger, thenreverse the hoses to the cooler so you can flush inthe opposite direction. Repeat steps 8 through 10.
12. Release the trigger. and rinse the cooler with wateronly for one minute.
13, Turn the water valve off, and turn off the water supply.
'14. Turn the air valve on to dry the system out with airfor two full minutes or until no moisture is visibleleaving the drain hose.
CAUTION: Rosidual mobturo in the qooler or linescln damage the transmission,
15. Remove the flusher from the cooler line. Attach thedrain hose to a container.
16. Install the transmission. and leave the drain hoseattached to the cooler line.

17.Make sure the transmission is in the E] position.
Fill the transmission with cvT Fluid, and run the
engine for 30 seconds or until approximately 0 95 {
(1.0 US qt.,0.8 lmp qt.) is discharged.
Remove the drain hose, and reconnect the cooler
return hose to the transmission (see page 14-355)
Refill the transmission with CVT Fluid to the proper
level (see page 14-299).

TOOL MAINTENANCE
1. Empty and rinse after each use. Fill the can with water
and pressurize the can. Flush the discharge line to
ensure that the unit is clean.
2, lf discharge liquid does not foam, the orifice may be
blocked.
3. To clean, disconnect the plumbing from the tank at
the large couPling nut.
