Road Test
NOTE: Warm up the engine to normal operating temperature (the radiator fan com6s on).
1. Apply the parking brake and block the wheels. Start the engine, then shift to the E position while depressing the
brake pedal. Depress the accelerator pedal and release it suddenly. The engine should not stall.
2. Test in E position
Park the vehicle in a slope (approx. 16'). apply the parking brake, and shift into E position. Release the brake; the
vehicle should not move.
3. Test-drive the vehicle on a flat road in the position shown in the table. Check that the engine speeds meet the approx-imate vehicle speeds shown in the table.
NOTE: Throttle position sensor voltage represents the throttle opening. To monitor the throttle position sensor volt-age, use one of the following methods:
A. Connect the Honda PGM Tester, and go to the PGM-FI Data List.
A1For road testing on '96 - 98 models, remove the drive/s side kick panel to expose the TCM; on '99 - OO models,remove the passenger's side kick panel to expose the PCM (see page l,[-236),
Set the digital multimeter to check throttle position sensor voltage between terminals:. '96 - 98 modols: TCM 84 {+} and Aa (-) or A17 (-1.. '99 - 0O models: FCM C27 {+l and 820 (-l ot 822 l-1.

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.

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.

Transmission
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.
