  8. Calculate the following formula and determine the amount of cable adjustment.

    T mm = (A - B) x 0.56

    [T in = (A - B) x 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 adjustment procedures.

    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 adjustment 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 install the stay.

    Tightening torque: 

    T: 32 N.m (3.3 kgf-m, 23.6 ft-lb)
