TRANSMISSION ASSEMBLY
When installing transmission to the engine, attach the bolts in theorder as shown.
CAUTION:
When replacing an engine or transmission you must make
sure the dowels are installe d correctly during re-assembly.
Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.
NOTE:
*: No.2 bolt also secures air breather vent.
Align the positions of bolts for drive plate with those of the torque converter, and temporarily tight en the bolts. Then tighten the bolts
with the specified torque. Refer to TM-214, "Removal and Installa-
tion (2WD)".
CAUTION:
When turning crankshaft, turn it clockwise as viewed from
the front of the engine.
After converter is installed to drive plate, rotate crankshaft several turns and check to be su re that transmission rotates
freely without binding.
Install crankshaft position sensor (POS).
After completing installation check fluid leakage, fluid level and the positions of A/T. Refer to TM-179, "Checking the A/T Fluid (ATF)"
, TM-195, "Checking of A/T Position" and
TM-195, "Adjustment of A/T Position"

INSPECTION
Installation and Inspection of Torque Converter
After inserting a torque converter to a transmission, be sure to check distance A to ensure it is within specifications.
INSTALLATION
Installation of the remaining components is in the revers e order of removal, while paying attention to the fol-
lowing:
When installing transmission to the engine, attach the bolts as shown.
CAUTION:
When replacing an engine or transmission you must make sure the dowels are installed correctly during re-assembly.
Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drivetrain components.
NOTE:
*: No.2 bolt also secures air breather vent.
Align the positions of bolts for dr ive plate with those of the torque
converter, and temporarily tighten the bolts. Then tighten the bolts
with the specified torque. Refer to TM-216, "Removal and Installa-
tion (4WD)".
CAUTION:
When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that transmission rotates
freely without binding.
Install crankshaft position sensor (POS).
After completing installation, check fluid leakage, fluid level, and the positions of A/T. Refer to TM-179, "Checking the A/T Fluid (ATF)"
, TM-195, "Checking of A/T Position"
and TM-195, "Adjustment of A/T Position".

DISASSEMBLY
27. Push A/T assembly harness connector.CAUTION:
Do not damage connector.
28. Remove oil pan and oil pan gasket. Refer to TM-201, "Oil Pan"
.
29. Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.
If frictional material is de tected, perform A/T fluid cooler
cleaning. Refer to TM-183, "A/T Fluid Cooler Cleaning"
.
30. Remove magnets from oil pan.
31. Disconnect A/T fluid temperat ure sensor 2 connector (A).
CAUTION:
Do not damage connector.
32. Straighten terminal clip to free terminal cord assembly and A/ T fluid temperature sensor 2 harness.
33. Disconnect output sensor connector. CAUTION:
Do not damage connector.
34. Straighten terminal clip to free output sensor harness.

Precaution for Working with HFC-134a (R-134a)INFOID:0000000003775256
WARNING:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refr igerant are not compatible. If the refrigerants
are mixed compressor failure is likely to occur. Refer to HA-4, "
Contaminated Refrigerant". To deter-
mine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use recovery/recycling equip-
ment and refrigerant identifier.
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If
oil other than that specified is used, compressor fa ilure is likely to occur.
• The specified HFC-134a (R-134a) oil rapidly absorb s moisture from the atmosphere. The following
handling precautions must be observed:
- When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of mois ture from the atmosphere.
- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the co mponents. Connect all refrigerant lo op components as quickly as possible
to minimize the entry of moisture into system.
- Only use the specified oil from a sealed container. Immediately r eseal containers of oil. Without
proper sealing, oil will become moisture saturat ed and should not be used.
- Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) from the A/C system usi ng certified service equipment meeting require-
ments of SAE J2210 [HFC-134a (R-134a) recycling eq uipment], or J2209 [HFC-134a (R-134a) recovery
equipment]. If accidental system discharge occurs , ventilate work area before resuming service.
Additional health and safety information may be ob tained from refrigerant and oil manufacturers.
- Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Precaution for Procedur e without Cowl Top CoverINFOID:0000000003775257
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
