So after my minivan has been sitting around for a few years I finally got around to installing a rebuilt A555 so I could drive it again. It took most of my weekend and a few busted knuckles but we got it installed. I am now having trouble putting it into first gear. When I first fire it up I can shift in and out of first normally but it soon becomes difficult to push into gear. After driving around the block I almost have to force it into gear. Then as soon as I shut the engine off it pops right into gear easily.

As much fun as pulling the transmission was, I really don't want to have to do it again anytime soon to replace a clutch or pp. Anybody have any ideas on what else could be causing this?
