The 350 I did myself but the 700 I let a shop do. They charged me £350 labour. To be honest, if I lived in the States I'd just buy a TCI trans complete. They're cheap and warrented. If you buy the parts yourself, the tranny shop prob won't warrent work as they'll blame it on 'your' parts. If the shop does it labour and parts, cheaper than a whole trans, make sure they've got a good rep.
