To do this remove all the screws and the cover plate from the lower front face of the clutch bell housing, then the bolts holding the bell housing to the engine. Bear the weight of the transaxle and pull it back perpendicular to prevent damaging the clutch disc while this main drive gear is engaged to its splined hub. Slowly turn each clutch cover bolt anticlockwise until all the springs pressure is released and then slowly take out the assembly out from the face of the flywheel, make sure the disc does not fall off. Connecting the transmission back to the engine can be done in reverse to putting on the clutch disc cover with the disc centered if it was removed. To start with, unless working on an automatic transmission, there is a cover plate on the lower front face of the converter housing which has to be removed after which loosening of the driveplate to torque converter bolts using the crankshaft in cases where they are not easily accessed. Locate the relative position of the driveplate to the torque converter, then immobilise the driveplate using a large screwdriver to jam the starter ring gear. Sustain the transmission on blocks and unbolt the converter bellhousing to engine bolts and then you can pull out the engine away from the torque converter, with the hoist or a floor jack, and to maintain the torque converter pressed at the rear, until it is fully locked within the oil pump. Reconnection involves the undoing of the above mentioned steps, ensuring that the torque converter and driveplate have their mating marks lined correctly and tightening of the bolts to the required torque.
