Gettin' a transmission out !

Hi Guys, First off, thanks for lettin' me join the Group, next, my poor Celica has 370,000 miles on it and I am just putting a new clutch and rear seal in it, I am by myself, I have a 'cherry picker' on the transmission, and I am having a problem getting the transmission loose from the engine, I have read the service manual and whatever tips I could get off of "you tube" and it doesn't want to give. Any ideas ? Thanks, greule2
