Just buy a seal up kit off ebay for $25.45 free shipping, but you'll need a special rear seal and a better pan gasket like $6.05 for red fiber; no cork, neoprene or rubber; either black or red fiber only. You'll have good internal seals and probably a good filter in there too.
That sounds a lot better than the $1250 a transmission shop quoted me for doing the work. For someone that's never worked on a transmission but has done other suspension and engine work, how complicated is this job?
