You can certainly tell if it's better for you to take it out through the top or not. Having removed my from the bottom several times, I just see it as a clean, clear way to do it without having to remove the seat and what ever else is in the way, in addition to tearing something inside the cab up. I've done mine whithout using a transmission jack, although I'll tell you a jack makes the job easier. You slide the tranny back to clear the bellhousing and lower her to the bottom and roll it out from under the cab.
