Rebuild help please

But I do a little help, I'm pulling the engine out and so far going ok, but the connector off the main harness that pig tails to the transmission and rear sensors, i'm having a hell of a time undoing the connector not enough room from the rear of the engine. So I'm wondering if anyone else had the same problem and what they're solution was.

 

While no one has replied to this post I finally got the connectors all undone it was a tight fit on some and same on the transmission bolts it was like hell but finally got that done, now the flywheel and the clutch plate convertor which O cannot see underneath the truck, but have seen guys on YouTube pulling engines out to the clutch plate intact, my question is can doing that damage the transmission pinning?
