  1. Install the select cable to plate assembly. Tightening torque: 18 N.m (1.8 kgf-m, 13.3 ft-lb)
  2. Install the select cable to the shifter arm.
  3. Install the plate assembly to transmission. Tightening torque: T: 25 N.m (2.5 kgf-m, 18.4 ft-lb)
  4. Install the washer and snap pin to the shifter arm.
  5. Install new clamp paying attention to the installing direction.
  6. Insert the tip of inner cable into connector hole of select lever, and fix the cable to bracket.
  7. Shift the select lever to the "N" range, and then adjust the select cable position. < Refer to «ADJUSTMENT»(ref-560386-S30877474342013061300000) , Select Cable. >
  8. Install the center exhaust cover. Tightening torque: 18 N.m (1.8 kgf-m, 13.3 ft-lb)
  9. Install the center exhaust pipe. < Refer to «INSTALLATION»(ref-560376-S27722973902013061300000) , Center Exhaust Pipe. >
  10. Lower the vehicle.
  11. Connect the battery ground terminal.

Check the removed cable and replace or adjust if damaged, rusty or malfunctioning.

  1. Check the cable for smooth operation.
  2. Check the inner cable for damage and rust.
  3. Check the outer cable for damage, bends and cracks.
  4. Check the boot for damage, cracks and deterioration.
  5. Move the select lever from "P" to "D" range. Check the existence of feel to contact the detents in each range. If the detents cannot be felt or the position pointer is improperly aligned, adjust the cable.
  6. Check if the starter motor rotates when the select lever is set to "P" range.
  7. Check the back-up light illumination when the select lever is in "R" range.
  8. Check the parking lock operation when the select lever is in "P" range.

  4. Remove the center exhaust cover.
  5. Loosen the adjusting nuts on both sides.
  6. Turn adjusting nut B until it lightly touches the connector.
  7. Set a spanner wrench to adjusting nut B so that it does not rotate, and then tighten the adjusting nut A. Tightening torque: 7.5 N.m (0.76 kgf-m, 5.5 ft-lb)
  8. After the completion of adjustment, confirm that the select lever operates normally at all ranges.
  9. Install in the reverse order of removal.

  1. Remove the AT select lever. < Refer to «REMOVAL»(ref-560386-S05039994422013061300000) , Select Lever. >
  2. Remove the spacer and gasket. < Refer to «DISASSEMBLY»(ref-560386-S30362977222013061300000) , Select Lever. >
  3. Using a flat tip screwdriver with a thin tip, remove the harness connector from the plate COMPL.
  4. Raise the claw using a flat tip screwdriver with a thin tip, and remove the solenoid unit from the plate COMPL.
  5. Using a flat tip screwdriver with a thin tip, remove the solenoid unit terminals from the harness connector.
StepCheckYesNo
1 CHECK SOLENOID UNIT. Measure the resistance of solenoid unit connector terminals. Terminals No. 4 - No. 3Is the resistance 27.6 - 30.5 ohms?Go to step 2 .Replace the solenoid unit. < Refer to AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH . >
2 CHECK SOLENOID UNIT. Connect the battery to the solenoid unit connector terminals, and then operate the solenoid. Terminals No. 3 (+) - No. 4 (-)Does the solenoid unit operate normally?Go to step 3 .Replace the solenoid unit. < Refer to AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH . >
3 CHECK "P" RANGE SWITCH. Shift the select lever to "P" range. Measure the resistance between "P" range switch connector terminals. Terminals No. 1 - No. 2Is the resistance less than 1 ohms?Go to step 4 .Replace the "P" range switch. < Refer to AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH . >
4 CHECK "P" RANGE SWITCH. Set the select lever to other than "P" range. Measure the resistance between "P" range switch connector terminals. Terminals No. 1 - No. 2Is the resistance 1 Mohms or more?NormalReplace the "P" range switch. < Refer to AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH . >
