–  Remove bolts -arrows- and remove pendulum support. –  Unscrew the protective plate for the torque converter from the gearbox.

–  Remove the three bolts securing the torque converter to the flywheel. To do so block the flywheel using the retaining tool -T20156-.

–  Remove the lower plate with the registry number from the gearbox and place retaining tool -T20155- so that the torque converter is immobilised. Tighten the tool's threaded bolt by hand.   Note Ensure that the bolt on retaining tool -T20155- is well tightened. If the bolt is not tightened well, the converter could disengage from the gearbox, and risk an accident when handling the gearbox during disassembly.

–  Fit the support stand -U 30025E-.   Note t  Fit the supporting equipment so that it is seated correctly on the hardest parts of the wing water drains and will not cause any damage. t  Ensure that the pipes and the cables in the area where the engine is suspended do not suffer any damage while fitting the hooks of the support device. –  Slightly tense the engine assembly/gearbox via the spindles.

–  Remove bolts -1- from the right support of the engine assembly.   Note Do not release the nut securing the console to the elastic block.

–  Release the securing bolts -arrows- of the engine assembly, gearbox side. –  Using the spindles of the support tool -U 30025E-, lower and tilt the engine assembly, until the tensioning roller is positioned slightly below the sill.   Note When lowering the engine assembly/gearbox ensure that the gearbox does not rest on the subframe. –  Connect the support -T20138B- on to the hydraulic jack -SAT 1040-.

–  Place the support -T20138B- underneath the gearbox, so that it is near as possible and parallel to the oil sump of the gear box. –  Secure the support -T20138B- at the front -arrow 1- with a nut and the left part -arrow 2- with an M10 bolt. The rear part -arrow 3- is fitted into one of the gearbox openings.   Note Tighten the fixed bolts on the support -T20138B- to lock the fixing bars and the central hexagonal nut. –  Extract the lower joining bolts from the engine/gearbox. –  Separate the gearbox from the engine, pressing down on the converter in order to disengage it from the flywheel. –  Turn the gearbox forwards using the spindles of the support -T20138B-. –  Lower the gearbox taking care not to damage any component.   Note Make sure that the torque converter does not become separated from the gearbox.
