I did as khansen suggested above with the short guide pin. I only used them to re-install and used a vicegrip to turn it out afterwards.
Since I didn't need to service the transmission, I strapped it securely on an ATV type platform jack to maintain orientation for installation.
Unfortunately I have had to do this 3 times. First because I misdiagnosed my clutch noise as a bad throwout bearing.
Immediately after I had to do it again because I thought I could attach the release arm after installing the transmission- you can't.
I finally cured my clutch noise by replacing the bronze colored steel pilot bushing with a proper OEM brass bushing.
Don't use the the darn steel ones most suppliers sell.
