Cooler Flushing
!!!@ To prevent iniury to. face and eyas, always
-ea. safetv glasses ot a face shield when using the
transmission flusher.
NOTE: This procedure should be performed before rein-
stalling the transmission.
1. Check the tool and hoses for wear and cracks before
using. lf wear or cracks are found, replace the hoses
before using.
Using the measuring cup, fill the tank with 2'l ounces
(approximately 2/3 full) of biodegradable flushing
fluid (J35944 - 20). Do not substitute with any other
fluid. Follow the handling procedure on the fluid
contarner.
Secure the flusher filler cap, and pressurize the tank
with compressed air to between 550 - 829 kpa (5 6 -
8.45 kgflcm'. 80 - 120Psi).
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
Hang the tool under the vehicle.
Attach the tank's discharge hose to the return line
of 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 oJ the drain hose to a
bucket or floor drain.

NOTE; lf water does not tlow through the cooler, it
is completely plugged. cannot be flushed, and must
be replaced.
9. Depress the trigger to mix the flushing fluid into the
water flow. Use the wire clip to hold the trigger down'
While flushing with the water and flushing fluid for
two minutes, turn the air valve on for five seconds
everv 15 - 20 seconds to create a surging action'
AIR PRESSURE: MAX 845 kpa {8.45 kgf/cm', 120 psi)
Turn the water valve off. Release the trigger, then
reverse the hoses to the cooler so you can flush in
the opposite direction. Repeat steps 8 through 10'
12, Release the trigger, and rinse the cooler with water
onlv 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 air
for two full minutes or until no moisture is visible
leaving the drain hose.
CAUTION: Residual mobturo in tho cooler or pipas
can damage the transmksion'
15. Remove the flusher from the cooler line. Attach the
drain hose to a contalner.
16. Install the transmission, and leave the drain hose
attached to the cooler line

models, the TCM or PCM memorizes ths loodback sig'
nals when you drive the vehicle.
1. Engage the parking brake, and block the front
wheels securely.
2. Connect the SCS service connector to the Service
Check Connector as shown. (The Service Check
connector (2P) is located under the dash on the
passenger's side of the vehicle.)

. With the combination light switch OFF.
. With the heater fan switch OFF.
. Turn OFF all other electrical systems
NOTE: Start step 5 within 60 seconds after the radi-
ator fan goes off.
Shift into E position, and let the engine idle for two
minutes to store the feedback signal in memory
under the same conditions as in step 5.
Connect the Honda PGM Tester. Check that the TCM
has completed the start clutch calibration.
NOTE:
. The TCM will not store the feedback signal when
the CVT fluid temperature is below 40"C (104'F)
even if the engine coolant temperature reaches
the normal operating temperature.
. Repeat these procedures until the start clutch
calibration is completed-
Disconnect the SCS service connector from the
Service Check Connector.
'97 - 00 Models
The TCM ('97 - 98 models) and PCM ('99 - 00 models)
memorize the feedback signal when you drive the
vehicle as follows:
. After warming up the engine (the radiator fan

. Shift into E position.
. Turn OFF all electrical systems,
. Drive the vehicle up to the speed 37 mph (60

. After the speed reaches 37 mph (60 km/h),
release the accelerator for 5 seconds.

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.

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
