Yeah, I 2nd that, if you buy a decent seal (check parts Dino) it won't just push right in. I did it outside the car and had a bit of trouble with it. Doing it in the car I can't imagine, but it'll definitely be harder. You should be able to do it though. I would def take the tranny copletely out. This will be a lot easier if you a manual. I'd guess if you started in the morning you'd be done by mid afternoon. That includes start to finish driving the car in and out. Maybe dinner time if you have trouble ... you know how car jobs go. :thumbsup
