Im getting ready to pull the motor and I would like to leave the tranny ( t-3650) in place. I have pulled both as a unit in the past and also have dropped the trans first but this time I would like to leave the trans in place.
I personally always pull just the engine, and leave the transmission in place. It's enough fun just getting the engine out, without adding the extra complication of a long transmission on the end of the engine. Sometimes I even pull the transmission first. While the engine is out, I might as well check the transmission, and at least check/adjust the end play.
I've pulled my motor without the trans and left it in place. I just left a jack under the transmission so it didn't move from the place where it separated from the block. Made installing the motor a lot easier. Also, I'm sure you already know, but pulling the radiator and everything gives in front of the motor gives you ungodly amounts of room. Haha.
Seriously though, if you have a way to get the car up high enough, unbolt the k member and tranny cross member and leave it all on the ground and and just raise the car up.
