Update:
I performed my transmission service today. I started by degreasing the undercarriage with Purple Power (man, I love that stuff). BTW, Thanks a lot Ford for clipping the cat heat shield to the trans pan. Once I got that figured out it went easily, but that's one messy-ass job. You've got the trans x-member in the rear and the catalytic converter in the front. I chose to drop the rear first thinking that was better than getting the cat full of oil. Then of course the oil runs down both sides of the trans x-member, but I was ready for it with my large drip pan and 2 drain pans. There was still a lot of oil in the drip pan. I spilled about a 1/4 qt of oil, but at least it ended up in the drip pan rather than on my driveway.
Once I installed the new Wix trans filter I cleaned the trans pan. The pan and magnet weren't too bad at all, but the fluid looked more like engine oil with 8,000 miles on it than trans fluid. No hint of pink (probably the original fluid w/184k on it). Then I figured out a good place to install the transmission drain, drilled the hole and installed the drain plug, reinstalled the pan and went and took a long shower. As I sit here writing this I just remembered I forgot to clip the heat shield back into place. I'll do that after dinner (with rubber gloves on to stay clean) and then refill the trans. 4 qts is what came out, so that's where I'll start putting it back in and adjust, as necessary, from there. Edit: Done. As I recall it was about a 1/2 qt low to begin with. As the fluid was so dirty, I figure I'll run this fluid for a while and then drain it (using my hand-dandy drain plug) and refill the trans with fresh fluid again.
I guess the driver's seat bottom replacement will be my next project, when I come up with the $200 for the new leather cover.
I'm thinking maybe I should replace my hydraulic chain tensioners. I see them on eBay for as little as $30 a pair (probably made in China). Does any one know a decent brand, or do you think I should stay with Motorcraft? I see RockAuto sells Cloyes for around $75 for both with new washers.
