Disconnect all the connectors of the system wiring harness (DC Motor, Cultch Position Sensor and Transmission Control Unit) and remove the ‘Plastic Clip’ pulling it out from its threaded hole on the ‘Power Unit Base Plate’ body. 2. Remove the ‘Mechatronic Gear Actuator’ unit (MGA) first (refer the procedure 7. Mechatronic Gear Actuator Unit (MGA) Removal and Re-Fitment on Bench). Installation: 1. Assemble the new ‘Power Unit Base Plate’ on the fixture. 2. In order to guarantee right ‘Mechatronic Gear Actuator’ translation during the mounting, to avoid O-rings damages, screw ‘Special tool – guide rods’ φ6x100 mm length, with 15 mm threaded M6, in the ‘Power Unit Base Plate’ holes used by ‘Mechatronic Gear Actuator’ fixing screws. 3. Assemble the new O-rings on the new connectors. 4. Mount the new connectors with O-rings in their seats on new ‘Power Unit Base Plate’, after lubrication with new ‘CS Speed’ oil also lubricate the ‘Mechatronic Gear Actuator’ seats. 5. Remove traces of oil from the ‘Mechatronic Gear Actuator’ seal surface in contact with gasket with care to avoid contamination from foreign materials (dust, metal burrs, etc…) or surface damages. 6. Assemble the new gasket on the ‘Mechatronic Gear Actuator’ with the correct orientation, inserting the centering pins into the fixing holes of the ‘Mechatronic Gear Actuator’ body. 7. Position the ‘Mechatronic Gear Actuator’ with gasket over the ‘Power Unit Base Plate’ using the ‘Special tool – guide rods’ for reference and moving it parallel towards the mating surface.
