You'll need to disconnect the Bowden cable and the vacuum line at the engine; since they're out of the car, I'm assuming the shift rod/speedo cable/engine ground/oil cooler lines are already taken care of.

Since the assembly is out, it'll be easiest (IMO) to unbolt the tranny from the engine (17mm), pull it off, then unbolt the torque converter from the flywheel (forgot the size). Access the torque converter bolts by removing the dust cap at the bottom of the engine block, where it meets the tranny. You'll have to unbolt two at a time; there are six total.
