M/T OIL
Changing M/T OilINFOID:0000000001703134
DRAINING
1. Start engine and let it run to warm up transaxle.
2. Stop engine. Remove drain plug (1) and drain oil.
3. Install a new gasket onto drain plug (1) and install it into tran-
saxle. Tighten drain plug to specification. Refer to MT-17, "
Dis-
assembly and Assembly".
CAUTION:
Do not reuse gasket.
FILLING
1. Remove filler plug (1). Fill with new oil until oil level reaches the
specified limit at filler plug hole as shown.
2. After refilling oil, check oil level. Install a new gasket on filler plug
(1), then install it into transaxle. Tighten filler plug to specifica-
tion. Refer to MT-17, "
Disassembly and Assembly".
CAUTION:
Do not reuse gasket.
Checking M/T OilINFOID:0000000001703135
OIL LEAKAGE AND OIL LEVEL
1. Make sure that oil is not leaking from transaxle or around it.
2. Remove filler plug (1) and check oil level at filler plug hole as
shown.
CAUTION:
Do not start engine while checking oil level.
3.
Install a new gasket onto filler plug (1) and install it into tran-
saxle. Tighten filler plug to specification. Refer to MT-17, "
Disas-
sembly and Assembly".
CAUTION:
Do not reuse gasket.

When installing transaxle assembly, be careful not to bring transaxle input shaft into contact with
clutch cover.
• If transaxle is removed from the vehicle, always replace CSC. Refer to CL-11, "
Removal and Installation".
• When installing the transaxle assembly to the engine, install the
bolts as shown.
A: M/T to engine
B: Engine to M/T
• After installation, bleed the air from the clutch hydraulic system. Refer to CL-8, "
Air Bleeding Procedure".
• After installation, check oil level, and check for leaks and loose mechanisms. Refer to MA-21, "
Checking M/
T Oil".

Gauge indication Refrigerant cycle Probable cause Corrective action
Both high- and low-pressure
sides are too low.• There is a big temperature dif-
ference between liquid tank
outlet and inlet. Outlet tem-
perature is extremely low.
• Liquid tank inlet and expan-
sion valve are frosted.Liquid tank inside is slightly
clogged.• Replace liquid tank.
• Check oil for contamination.
• Temperature of expansion
valve inlet is extremely low as
compared with areas near liq-
uid tank.
• Expansion valve inlet may be
frosted.
• Temperature difference oc-
curs somewhere in high-pres-
sure side.High-pressure pipe located be-
tween liquid tank and expansion
valve is clogged.• Check and repair malfunc-
tioning parts.
• Check oil for contamination.
Expansion valve and liquid tank
are warm or only cool when
touched.Low refrigerant charge.

Leaking fittings or componentsCheck refrigerant for leaks.
Refer to MTC-84, "
Checking of
Refrigerant Leaks" .
There is a big temperature dif-
ference between expansion
valve inlet and outlet while the
valve itself is frosted.Expansion valve closes a little
compared with the specification.
↓
1. Improper expansion valve
adjustment.
2. Malfunctioning expansion
valve.
3. Outlet and inlet may be
clogged.• Remove foreign particles by
using compressed air.
• Replace expansion valve.
• Check oil for contamination.
An area of the low-pressure pipe
is colder than areas near the
evaporator outlet.Low-pressure pipe is clogged or
crushed.• Check and repair malfunc-
tioning parts.
• Check oil for contamination.
Air flow volume is not enough or
is too low.Evaporator is frozen.• Check thermo control amp.
Refer to MTC-37, "
Magnet
Clutch Circuit (If Equipped)"
.
• Replace compressor.
• Repair evaporator fins.
• Replace evaporator.
• Refer to MTC-33, "
Front
