Can you remove flywheel without removeing
No. Kinda like removing your socks without taking off your shoes.
You can move your trans back. You dont hace to completely remove it. Ive done it before
Many years ago, I built up blocks under the tranny pan, then scooted the tranny backwards, two or three inches may give you enough room to get at the flywheel bolts. Then when going back with everything just scoot the tranny forward. I didn't have a transmission jack or anything.
