I'm going to try and do it this weekend if I can get a hold of our lift (currently my fathers Firebird occupies it for a heads/cam swap, guess he got tired of the boy wuppin his all day long:) ), If I can get it done I am going to be pulling the pan and filter as well and putting in a trans cooler, I'll get a good writeup for ya but it is a super easy (but messy) job. Biggest deal with any AT is any part you pull off clean it till your hands bleed. You want it to be like new when you put it back on. really here is the whole deal if I can't get it done.
