1.CHECK STARTING OUT FROM D1
1. Drive the vehicle for about 10 minutes to warm up the engine oil and ATF. Appropriate temperature for the ATF: 50 - 80° C (122 - 176°F)
2. Park the vehicle on a level surface.
3. Move selector lever to “P” position.
4. Start the engine.
5. Move selector lever to “D” position.
6. Press the accelerator pedal about half way down to accelerate the vehicle.
With CONSULT-III
Read off the gear positions.
Starts from D1?
YES >> GO TO 2.
NO >> Record the malfunction, GO TO 2.
2.CHECK SHIFT-UP D1 → D2
Press down the accelerator pedal about half way and inspect if the vehicle shifts up (D1 → D2) at the appropri-
ate speed.
• Refer to TM-265, "
Vehicle Speed at Which Gear Shifting Occurs".
With CONSULT-III
Read the gear position, throttle degree of opening, and vehicle speed.
Does the A/T shift-up D1
→ D2 at the correct speed?
YES >> GO TO 3.
NO >> Record the malfunction, GO TO 3.

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".
