you dont have to pull the trany but i would recomend it couse when you go tho put the motor back in it a pian to line up, But take the rad out and pull the motor forward when its loose so it slids off the input shaft but like i said its a pain when you go to line it back up and its very easy to drop a trans. Well hope that helps
no, tranny does not have to come out w/ the engine. but if you leave tranny in, you'll have to leave a jack under the tranny or use something else to support the front of it while the engine is not in place...good luck with it
