6. Check A/T fluid condition.

If ATF is very dark or smells burned, checking operation of A/
T. Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)" .
7. Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.
Changing A/T FluidBCS000ZM
1. Warm up ATF.
2. Stop engine.
3. Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained ATF.
CAUTION:
Do not reuse drain plug gasket.
4. Run engine at idle speed for 5 minutes.
5. Check A/T fluid level and condition. Refer to AT- 1 4 , "
Checking A/T Fluid" . If ATF is still dirty, repeat steps
2 through 5.

ON-VEHICLE SERVICE

3. Disconnect terminal cord assembly harness connector.
4. Remove snap ring from terminal body.
5. Remove terminal cord assembly by pushing terminal body into
transaxle case.
6. Remove engine under cover.
7. Remove front LH nut of front suspension member, and then
lower front LH of front suspension member to secure a space for
removing control valve assembly.
8. Drain ATF from A/T. Refer to AT- 1 5 , "
Changing A/T Fluid" .
9. Remove oil pan and oil pan gasket.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-13, "
RADIATOR" , CO-16,
"RADIATOR (ALUMINUM TYPE)" (QR engine) or CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)"
(VQ engine).
11. Remove control valve assembly fixing bolts A, B and C .

DISASSEMBLY

5. Set manual shaft to “P” position.
6. Remove PNP switch.
7. Remove bracket from transaxle case.
8. Remove revolution sensor from transaxle case.
9. Remove O-ring from revolution sensor.
10. Remove turbine revolution sensor (power train revolution sen-
sor) from transaxle case.
11. Remove O-ring from turbine revolution sensor (power train revo-
lution sensor).
12. Remove oil pan fitting bolts.
13. Remove oil pan and oil pan gasket.
14. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T.
15. Remove magnets from oil pan.
16. Remove control valve assembly according to the following procedures.
a. Remove snap ring from terminal body.
CAUTION:
Do not expand snap ring excessively.
b. Push terminal body into transaxle case and draw out terminal
cord assembly.

HEATER & COOLING UNIT ASSEMBLY

10. Remove mounting bolts from heater & cooling unit.
11. Remove steering column mounting nuts.
12. Remove steering member mounting bolts.
13. Remove steering member, and then remove heater & cooling unit.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings of A/C piping with new ones, and then apply compressor oil to it when installing
it.

Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.

Insert piping securely until a click is heard.

After piping connection is completed, pull male-side piping by hand to make sure that connection
does not come loose.

When recharging refrigerant, check for leaks.
NOTE:

When filling radiator with coolant, refer to CO-10, "Changing Engine Coolant" (QR engine) or CO-34,
"Changing Engine Coolant" (VQ engine).

Recharge the refrigerant.
