I have a 2001 Hyundai Accent Automatic, can u please help me by answering. Does the whole engine/gearbox have to be lifted out together or can u pull the LHS wheel ect... off and remove gearbox that way? would like to change gearbox

As you have to support/tilt the engine somewhat to remove the gearbox/diff.i personally find it easier to remove the whole unit.then support it on a stand and do any work needed before refitting(when its out you can do the timing belt.water pump,or anything else you want.without leaning over fenders or stretching to get to things BUT no doubt someone will disagree.

NOT at all you leave the engine in the car you use a engine support cradle to hold the engine upright so when you disconnect the engine mounts from underneath the engine stays supported. find out what supports the engine underneath , and will the gearbox fit when lower control arm ball joint removed.
