TRANSMISSION ASSEMBLY

INSPECTION
Installation and Inspection of Torque Converter

●

After inserting a torque converter to a transmission, be sure to
check dimension A to ensure it is within the reference value
limit.

INSTALLATION

Install the removed parts in the reverse order of the removal, while paying attention to the following work.

●

When installing transmission to the engine, attach the fixing
bolts in accordance with the following standard.

*: Tightening the bolt With A/T fluid charging pipe.

●

Align the positions of tightening bolts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then,
tighten the bolts with the specified torque.

CAUTION:

●

When turning crankshaft, turn it clockwise as viewed from
the front of the engine.

●

When tightening the tightening bolts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts.

●

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). Refer to 

EM-25, "Removal and Installation"

 .

●

After completing installation, check fluid leakage, fluid level, and the positions of A/T. Refer to 

AT-14,

"Checking A/T Fluid"

 , 

AT-282, "Adjustment of A/T Position"

 , 

AT-282, "Checking of A/T Position"

 .

●

When replacing the A/T assembly, erase EEP ROM in TCM. Refer to 

AT-8, "Precautions for A/T Assembly

Replacement"
