As long as non of the bolts/nuts during removal aren't seized it should take no more than a few hours using basic hand tools. I have done it a few times already, and it gets easier and easier. A tranny jack is a very very helpful tool. If you have the extra $$ get one. Air tools make everything easier as well.
Get these...there are two bolts at the top of the bellhousing that require external torx. After you remove them, replace them with standard hex head bolts.
