Transmission fluid was pretty bad so I'm wondering if I should exchange all of it now, if I can somehow get the drain plug loosened I could just fill new fluid while draining the old right? Another good thing was that there was absolutely nothing on the magnet in the transmission pan.

to remove the drain plug you must first have a 6 point socket with NO tapered edge . then you remove the pan and secure on a piece of plywood etc .. secure the pan with a clamp so it will not move .. then you heat up the drain plug with a torch until you see the plug glow slightly red . the you quickly apply torque to unscrew this plug. MAKE SURE YOU USE GOGGLES TO PROTECT EYES !
GM used permanent lock tight . this is why .
when installing the plug I used a small amount of thread sealant for machined threads.
when I did this ,,,, when the plug broke loose the lock tight exploded out ward !
