if you are doing it yourself and don't have a tranny jack. i would highly suggest taking the t case off (and adaptor) first from the back of the trans.
the trans and converter are going to weigh in about 140#.
i've shipped them before and a bare trans minus bellhousing is roughly aroud 100#, so figure in a converter, bellhousing and i say close to my number.
might want to drain the converter while unbolting the flexplate. this way if it slips out whileyoua re dropping it you won't have multiple quarts of fluid finding thier way onto your garage floor. there should be a drain plug next to one of the studs.
