INSPECTION
Installation and Inspection of Torque Converter
After inserting a torque converter to a A/T, be sure to check dis-
tance “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 A/T assembly to the engine assembly, attach the
fixing bolts in accordance with the following standard.
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. Refer to AT- 2 7 5 ,
"COMPONENTS" .
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. Refer to EM-72, "
INSTALLATION" .
After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that A/T rotates freely without binding.
Install crankshaft position sensor (POS). Refer to EM-36, "Removal and Installation (AWD Models)" .
After completing installation, check A/T fluid leakage, A/T fluid level and A/T position. Refer to AT- 1 3 ,
"Checking A/T Fluid" , AT-228, "Checking of A/T Position" . Distance “A”: 25.0 mm (0.98 in) or more

28. Remove oil pan and oil pan gasket.
29. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
30. Remove magnets from oil pan.
31. Disconnect A/T fluid temperature sensor 2 connector.
CAUTION:
Be careful not to damage connector.
32. Straighten terminal clips to free terminal cord assembly and A/T
fluid temperature sensor 2 harness.
