2. Remove manual lever from A/T.
3. Remove control rod from vehicle.
INSTALLATION
Note the following, and install in the reverse order of removal.

After installation is completed, adjust and check A/T position. Refer to AT- 2 0 6 , "Adjustment of A/T Posi-
tion" and AT- 2 0 6 , "Checking of A/T Position" .
Adjustment of A/T PositionNCS0008U
1. Loosen nut of control rod.
2. Place PNP switch and selector lever in “P” position.
3. While pressing lower lever toward rear of vehicle (in “P” position
direction), tighten nut to the specified torque. Refer toAT- 2 0 5 ,
"CONTROL ROD COMPONENTS"
Checking of A/T PositionNCS0008V
1. Place selector lever in “P” position, and turn ignition switch ON.
2. Make sure that selector lever can be shifted to other than “P” position when brake pedal is depressed.
Also make sure that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
9. Make sure that transmission is locked completely in “P” position.
10. When selector lever is set to manual shift gate, make sure that manual mode is displayed on combination
meter.
Shift selector lever to “+” and “-” sides, and check that set shift position changes.

When installing A/T assembly to the engine assembly, attach the
fixing bolts in accordance with the following standard.
–: Engine to transmission
–: Transmission to engine

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 torque converter
after fixing crankshaft pulley bolts, be sure to confirm the
tightening torque of crankshaft pulley mounting bolts.
Refer to EM-53, "
TIMING CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that
