Removal
Preparations
Switch off the ignition.
Removing the air cleaner (ACL) housing
Remove the air cleaner housing ACL assembly with the intake pipe.
Removing the gear selector cable from the lever on the gearbox
Remove the mechanical transmission cable from the lever on the transmission. Use jimmy bar 999 7077 Jimmy bar 999 7077 Jimmy Bar.
Unhook the mounting with the connectors for the gearbox from the bracket for the air cleaner (ACL) housing.
Removing the lever on the gear shift linkage rod
Remove:
- the lever on the gear shift linkage rod
- the screw for the gear selector sensor and cable harness.
Twist out the tab on the cable harness holder.
Installing the lifting beams and lifting hooks on the engine lifting lugs
Note! The front lifting beam must be equipped with fixture kit 999 7070 Mounting 999 7070 Mounting as illustrated.
Position lifting beam 999 5716 Reading off tool 999 5716 Reading Off Tool on the wheel arch and directly above the engine lifting eyelets on the left and right-hand sides.
Fasten lifting hooks 999 5460 Lifting hook 999 5460 Lifting Hook and 999 5185 HOOK 999 5185 Hook to the engine lifting lugs. Tighten to light contact.

Carefully tap it in between the cover and gearbox so as not to bend the seal flange on the cover.
Clean the gasket residue from the cover and the gearbox.
Removing the cable harness
Remove:
- the connectors for the solenoid valves
- the screw for the oil temperature sensor holder.
Remove the sensor from the control system.
Remove:
- the cable harness from the holders on the control system
- the cable harness.
Installation
Note! For tightening torques, see: Tightening Torque
Connecting the cable harness
Lubricate the O-rings for the cable harness grommet and the oil temperature sensor with automatic gearbox fluid.
Install:
- the cable harness. Connect the connectors to the solenoids
- the oil temperature sensor with the holder and screw. Tighten to 10 Nm
- the cable harness on the holder. Check that the cable harness is correctly positioned.
Sealing the cover
Check that the mating surface for the cover is level.
Wipe the cleaned mating surfaces on the cover and gearbox. Use methylated spirit.
Note! Ensure that no dirt gets into the gearbox.
Apply a bead of sealing compound, approximately 3 mm thick, to the cover. P/N 1161409-6. Apply the compound around the screw holes.
Installing the control system cover
Reinstall the control system cover on the gearbox. Tighten the screws alternately. Tighten to 12 Nm. Torx TX 40.
Install:

Installing the sub-frame
Install the sub-frame. See: Sub-frame front, replacing Service and Repair.
Remove the lifting beams and lifting hooks
Twist in the tab on the cable harness holder.
Install:
- the screw for the gear-shift position sensor and holder. Tighten to 25 Nm
- the lever for the gear shift linkage rod. Tighten the nut. Tighten to 16 Nm
- the mechanical gearbox cable on the lever.
Installing the air cleaner (ACL) housing
Install the air cleaner (ACL) housing, including all hoses and electrical terminals. See Gear selector cables, replacing Gear Selector Cables, Replace.
Top up with new oil, part no. 116 1540-8, using the same quantity that was drained earlier. See Transmission fluid, replacing Transmission Fluid, Replacing. Top up and check the oil level. See Oil level, checking Checking Oil Level.
Note! After replacing the transmission oil, the "Transmission oil change" counter must be reset. See Transmission fluid, replacing Transmission Fluid, Replacing.
