D: ADJUSTMENT

1) Lift up the vehicle.

2) Remove the transmission under cover.

3) Remove the center exhaust pipe. <Ref. to

EX(STI)-8, REMOVAL, Center Exhaust Pipe.>

4) Remove the heat shield cover.

5) Remove the crossmember. <Ref. to 6MT-29,

REMOVAL, Transmission Mounting System.>

6) Measure the distance “A” from the shift bracket

seating face on transmission side to the hole edge

of the reverse check lever.

7) Measure the distance “B” from the shift bracket

seating face on transmission side to the hole edge

of the extension case.

8) Calculate the following formula and determine

the amount of cable adjustment.

T mm = (A – B) × 0.56

[T in = (A – B) × 0.56]

T: Amount of cable adjustment

A: Distance from the shift bracket seating face on

transmission side to the hole edge of the reverse

check lever

B: Distance from the shift bracket seating face on

transmission side to the hole edge of the extension

case
NOTE:

• If the value “T” (amount of cable adjustment) is

positive (+), shorten the length “C” (from cable plate

edge to reverse check cable) by using adjustment

procedures.

• If the value “T” (amount of cable adjustment) is

negative (–), lengthen the length “C” (from cable

plate edge to reverse check cable) by using adjust-

ment procedures.

Reverse Check Cable

CONTROL SYSTEMS

9) Remove the snap pin and washer, and separate

the reverse check cable from the reverse check le-

ver.

10) Move the transmission to the right side, and re-

move the stay bolts and the reverse check cable.
NOTE:

If the transmission is not moved aside, the stay

bolts may contact the body and cause damage.

11) Check the adjustment of the reverse check ca-

ble.

(1) Add a marking on the reverse check cable.

(2) According to the value “T” (amount of cable

adjustment) calculated in the step 8), turn the

lock nut of reverse check cable back and forth,

then adjust the length “C” (from cable plate

edge to reverse check cable).

NOTE:

• Turning the lock nut toward front of the vehicle

makes the cable length shorter and toward the rear

of the vehicle the cable length longer.

• The amount of the cable adjustment by one lock

nut rotation is 1 mm (0.04 in).

• Turn the lock nuts on both sides by the same ad-

justment amount.

(3) Tighten the lock nut.

Tightening torque:

6 N·m (0.6 kgf-m, 4.4 ft-lb)

12) Move the transmission to the right side, and in-

stall the stay.

13) Install the reverse check cable, washer and

snap pin to the reverse check lever.
NOTE:

Make sure to point the snap pin in an appropriate

direction.

14) Make sure the hole of extension case is aligned

with that of reverse check lever. If the hole posi-

tions are not aligned, return to the step 6) and re-

peat the adjustment procedures of the reverse

check cable.
NOTE:

• Check that the M3 bolt goes through the hole of

reverse check lever and can be inserted into the

hole of extension case.

• When checking visually, confirm that the gap of

hole positions is 0.5 mm (0.02 in) or less.

NOTE:

If the hole positions are not aligned after repeating

the reverse check cable adjustment, adjust the ca-

ble hole position to the reference standard.
Distance from the shift bracket seating face on

transmission side to the hole edge of the re-

verse check lever “A”:
