Pulling/reinstalling the trans is 99 percent of the work. If you're gonna do it, take the time to tear it down and go through it. Very basic stuff, probably the easiest part of that car you'll ever have to rebuild. Instructions/specs easily found online and parts are readily available. Good luck and enjoy..BTW, I personally would never replace any part that checks out as good...Almost ANYTHING you buy these days is questionable at best...
