Ok, so ive went though almost all of the posts and threads and cant find anything more than "make sure its lined up and the wiggle/twist until it fully seats/mates".
So i had to pull the trans to replace the clutch actuator/Slave cylinder. Not only were the 3 bolts holding that in all seized and fought me but now the trans wont completely mate. I am confident that the splines are lines up because if i grab and turn one of the wheel hubs the other side turns with it no issues there. I did have to support the engine with a jack from bellow but other than that i cant see anything else that would cause it to bind up an stop the trans from fully mating. Like i was able to re-attach the front and rear motor/trans mounts and still no luck with the trans going all the way in....please any help would be amazing.
