2) Secure selector arm to shifter arm with shifter fork
screw

3. Shifter arm should be caught by pawl of rod.
Selector arm must be engaged with reverse check sleeve
assembly.
3) Adjustment of neutral position
(1) Shift gear into 3rd gear position.
(2) Shifter arm turns lightly toward the 1st/2nd gear
side but heavily toward the reverse gear side because
of the function of the return spring, until arm contacts
the stopper.
(3) Make adjustment so that the heavy stroke (reverse
side) is a little more than the light stroke (1st/2nd side).
(4) To adjust, remove bolts holding reverse check
sleeve assembly

4to the case, move sleeve assem-
bly outward, and place adjustment shim (0 to 1 ea.)
between sleeve assembly and case to adjust the clear-
ance.
CAUTION:
Be careful not to break O-ring when placing shim(s).

2) Installation of shifter arm
6
Install shifter arm into the partition from the front while
inserting selector arm into the opening in reverse check
sleeve. Pass shaft through hole in selector arm until its end
comes out of the rear of transmission case assembly.
CAUTION:
Apply a coat of gear oil to shifter arm. Also make sure
oil seal is positioned properly.
3) Adjustment of neutral position
NOTE:
After assembling and installing rear case, adjust neutral
position.
(1) Shift gear into 3rd gear position.
(2) Shifter arm turns lightly toward the 1st/2nd gear
side but heavily toward the reverse gear side because
of the function of the return spring, until arm contacts
the stopper.
(3) Make adjustment so that the heavy stroke (reverse
side) is a little more than the light stroke (1st/2nd side).

sleeve assembly to the case, move sleeve assembly
outward, and place adjustment shim (0 to 1 ea.)
between sleeve assembly and case to adjust the clear-
ance.

3. Rear Case (FWD Model)

G3M0564
(1) Place the transmission with case left side facing
downward and put ST1 on bearing cup.
(2) Screw retainer assembly into left case from the bot-
tom with ST2. Fit ST3 on the transmission main shaft.
Shift gear into 4th or 5th and turn the shaft several
times. Screw in the retainer while turning ST3 until a
slight resistance is felt on ST2.
This is the contact point of hypoid gear and drive pin-
ion shaft. Repeat the above sequence several times to
ensure the contact point.
ST1 399780104 WEIGHT
ST2 499787000 WRENCH ASSY
ST3 499927100 HANDLE
B3M0340A
(3) Remove weight and screw in retainer without
O-ring on the upper side and stop at the point where
slight resistance is felt.
NOTE:
At this point, the backlash between the hypoid gear and
drive pinion shaft is zero.
ST 499787000 WRENCH ASSY
B3M0334A
(4) Fit lock plate
11. Loosen the retainer on the lower
side by 1-1/2 notches of lock plate and turn in the
retainer on the upper side by the same amount in order
to obtain the backlash.
NOTE:
The notch on the lock plate moves by 1/2 notch if the plate
is turned upside down.
(5) Turn in the retainer on the upper side additionally
by 1 notch in order to apply preload on taper roller
bearing.
(6) Tighten temporarily both the upper and lower lock
plates and mark both holder and lock plate for later
readjustment.
(7) Turn transmission main shaft several times while
tapping around retainer lightly with plastic hammer.
(8) Set ST1 and ST2. Insert the needle through trans-
mission oil drain plug hole so that the needle comes in
contact with the tooth surface at a right angle and check
the backlash.

12) Selecting of main shaft rear plate
Using ST, measure the amount A of ball bearing protrusion
from transmission main case surface and select the proper
plate in the following table:

Dimension“A”
mm (in)Part No. Mark

(0.1524—0.1571)32294AA050 2
NOTE:
Before measuring, tap the end of main shaft with a plastic
hammer lightly in order to make the clearance zero
between the main case surface and the moving flange of
bearing.

2. INHIBITOR SWITCH
The inhibitor switch allows the back-up lights to turn on
when the select lever is in the R range and the starter
motor to start when the lever is in the N or P range. It also
monitors the input signal electronically controlled for each
range and turns on the corresponding range light on the
instrument panel.
When light operation, driving condition or starter motor
operation is erroneous, first check the shift linkage for
improper operation. If the shift linkage is functioning
properly, check the inhibitor switch.

(1) Disconnect cable end from select lever.
(2) Disconnect inhibitor switch connector.
(3) Check continuity in inhibitor switch circuits with
select lever moved to each position.
CAUTION:
Also check that continuity in ignition circuit does not
exist when selector lever is in R, D, 3, 2 and 1 ranges.
