Tips on Replacing Blown Tranny in '85 740 GL Sedan?

[Toolboy]

Hi, my folks have an '85 740 GL with a blown auto tranny. I would like to replace it for them, and have pulled and replaced tranny's and clutches in american and japanese light trucks. My question, are there any special considerations with this repair? Any tips on handy tools or tecniques? I know there will be a lot less space to work, and want to make sure I am capable of the repair before diving in. Any help would be greatly appreciated. Thanks and happy hollidays! Toolboy
