Cooler Flushing (cont'dl
Make sure the transmission is in the E position.
Fill the transmission with ATF, and run the enginefor 30 seconds or until approximately 0.95 f (1.0 USqt.,0.8 lmp qt.) is discharged.
Remove the drain hose, and reconnect the coolerreturn hose to the transmission (see page l4-192).
Refill the transmission with ATF to the oroDer level(see page 14-118).

TOOL MAINTENANCE
1. Empty and rinse after each use. Fill the can with waterand pressurize the can. Flush the discharge line toensure that the unit is clean.
2. lf discharge liquid does not foam, the orifice may beblocked.
3. To clean, disconnect the plumbing from the tank atthe large coupling nut.
ORIFICE
GRT{G
Remove the in-line filter from the discharge side andclean if necessary.
The fluid orifice is tocated behind the filter.Clean it with the pick stored in the bottom of thetank handle, or blow it clean with air. Securelvreassemble all Darts.

3. Check that the hole in the adjuster is perfectlyaligned with the hole in the shift cable. There aretwo holes in the adjuster. They are positioned 90.apart to allow cable adjustment in 1/4 turn incre-ments.
ExactAlignment
4. lf the hole is not perfectly aligned, loosen the lock-nut on the adjuster and adjust as required.
5. Tighten the tocknut to 7 N.m (0.7 kgf.m, 5 tbf.ft).
6. Install the lock pin on the adjuster. lf you feel thelock pin binding as you reinstall it, the cable is stillout of adjustment and must be readjusted.
7. Make sure the lock pin is seated in the adjustersecuretv.
8. Move the shift lever to each gear, and verify that theshift position indicator follows the automatic trans-axle gear position switch.
9. Start the engine, and check the shift lever in allgears. lf any gear does not work properly, refer totroubleshooting (see page 14-109 thru 1'4-'112).
10. Insert the ignition key into the key cylinder on theAy'T gear position indicator panel, and verify that theshift lock lever is released.

Start Clutch Calibration Procedure
NOTE: When the following parts are replaced, the TCM
must memorize the feedback signal for the start clutch
control.

. Transmissionassembly
. Stan clutch assembly
. Lower valve bodv assembly
. Engine assembly or overhaul
'96 Model Only
CAUTION: Do not uso this procsdure on'97 - (X) mod-
els or you will damage the transmission. On '97 - 00
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.)

Shift into E o|. E position. To store the engine
negative pressure in memory. Iet the engine idle in
E or E position for one minute under the follow-
ing conditions:
. With the brake pedal depressed,
. with the y'\/c switch oFF.
. 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
comes onl.
. Shift into E position.
. Turn OFF all electrical systems,
. Drive the vehicle up to the speed 37 mph (60
km/h).
. After the speed reaches 37 mph (60 km/h),
release the accelerator for 5 seconds.

Pressure Testing
. While testing, be careful of the rot8ling front wheels.
. M8k6 suro lifts, iacks, and satety stands are placed properly lsee section 11.
CAUTION:
. Before testing, be sur. the transmb3ion fluid is fillod to the propor lcvel.. Warm up the engin€ to nolmal operating tsmperature bofore testing. While t€sting, be 3ure not to allow dust and other loreign particles to onler into the transmi$ion.
1. Raise the front of the vehicle, and support it with safety stands (see section 1).
2. Set the parking brake. and block both rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop arid connect a tachometer.
5. Connect the special tool to each inspection hole.
