Been doing them for years, not that bad with a bit of common sense.most kit's don't come with all the part's,like band,thrust washers and such.For the most part I tell people that if they drove it till it just wouldn't move anymore they may need a second tranny for part's.This way i have usally what I need for spare parts.Also I highly recomend replacing the torque converter or having it checked by a quality shop.Some failers are a result of a bad converter.Tom
