5 or 6 speed box?
6 speed is a biggggggg heavy lump, 5 speed is manageable. Don’t take the engine out, don’t take the subframe off.
Air filter housing, battery and tray out to get access to top of box, under tray off, bottom half of n/s archliner off, n/s driveshaft off(gets it out the way so it’s not in the way), same with boost hose, disconnect o/s driveshaft and take off drive flange from gearbox(you won’t lose oil), pendulum mount off. Support engine in a safe manor that won’t slip or give way!! Take off gearbox mount completely from box, disconnect cables/hoses/bolts leave the 16mm head bolt below the starter till last as it will keep box in place till you are ready to remove it. I may have overlooked something but if it’s not obvious when doing the job you shouldn’t be doing it. As the box comes out you’ll thank me for mentioning removing o/s drive flange and n/s shaft, push the diff up and you’ll gain enough space to get it out.
Theres YouTube for checking the dual mass flywheel.
Rebuild is just a reverse of strip, bleeding the clutch can be a bitch depending on type.
Good luck
