Questions about pulling a motor out of 3G
 

I need to pull the motor out of a 90 T/A and a 91 Camaro (Motor swap). Do I have to pull the trans out with the motor or will I be able just to pull the motor?

You can pull the engine without the trans. I usually just put a jack on the front part of the transmission pan to support it while its unbolted from the engine.

That sounds simple enough. I heard that some of the bolts attaching trans to motor inaccessible that's why I asked

Bottom four are easy, can get with a socket or wrench. The top two can be a bitch. I prefer pulling the motor with the trans for ease of torquing the bolts down properly, but it can be done just pulling the motor, either use a box wrench or a socket with a super long extension setup for the top two bolts. They are up top roughly right near the intake/head meeting points. Manual trans cars I've found easier to pull the trans, as lining up the input shaft is much easier out of the car.

that and you can just unbolt it from the bellhousing
