8. Remove crankshaft position sens or (POS) from A/T assembly.
CAUTION:
• Do not subject it to impact by dropping or hitting it.
• Do not disassemble.
• Do not allow metal filings or foreign material to get on the
sensor front edge magnetic area.
• Do not place in an area affected by magnetism.
9. Remove fluid cooler tube.
10. Remove dust cover from converter housing.
11. Turn crankshaft to access and remove the four bolts for drive plate and torque converter.
CAUTION:
When turning crankshaft, turn it clockwise as viewed from
the front of the engine.
12. Support A/T assembly with a transmission jack. CAUTION:
When setting the transmission jack, be careful not to allow
it to collide agai nst the drain plug.
13. Remove cross member using power tool.
14. Remove air breather hose. Refer to TM-166, "
Removal and
Installation".
15. Disconnect A/T assembly connector.
16. Remove A/T fluid charging pipe from A/T assembly.
17. Plug any openings such as the A/T fluid charging pipe hole.
18. Remove the A/T assembly to engine bolts using power tool.
19. Remove A/T assembly from vehicle using transmission jack. CAUTION:
• Secure torque converter to prevent it from dropping.
• Secure A/T assembly to a transmission jack.

TRANSMISSION ASSEMBLY
• When installing transmission to the engine, attach the bolts in the order 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 tighten the bolts. Then tighten the bolts
with the specified torque. Refer to TM-186, "
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 sure that transmission rotates
freely without binding.
• Install crankshaft pos ition sensor (POS).
• After completing installation check fluid leakage, fluid level and the
positions of A/T. Refer to TM-148, "
Checking the A/T Fluid (ATF)", TM-164, "Checking of A/T Position" and
TM-164, "
Adjustment of A/T Position".
