OK... done. I got around to changing out the transmission fluid and filter today. I went and got fluid and filter from dealership, 1 filter and 12 quarts of fluid, $108.00. Less than I expected. The first thing I did was review some previous threads on here for information and watched a YouTube video, both helpful. I would have figured it out otherwise, might have made a bigger mess.
First, truck was in garage, on floor, no lift or stands. Transmission needs to be warm and exhaust needs to be HELLFIRE HOT so that all skin on hands can be thoroughly cooked. I Used a big pan, and a oil capture pan on top of that and still got some fluid on floor. Loosen dipstick bolt, then side bolts were removed, then ends, leaving corners in place. Then slowly removed rear corners, first loosening, then removing. When fluid starts to trickle out, STOP! and let fluid trickle out slowly. if you go too fast, fluid goes everywhere. As it is, fluid runs over cross member and exhaust. When flow begins to slow, remove rear corner bolts all the way. then slowly remove front bolts, holding pan up. Slowly lower pan and prepare for old filter to drop into pan with a splash.
Now clean off pan and gasket (reusable gasket), and clean magnet. Wipe off bottom edge of tranny and prepare to reinstall new filter and pan. I put filter on and held pan up, put 4 bolts in loosely and then finger tight. Put in rest of bolts, finger tight, then criss cross tightened to 98 in/lbs.
Now new fluid goes in. I used a hand pump that screws onto each little quart of fluid. Each little quart of fluid required 180 strokes of the pump to empty into tranny. Transmission was full when I started and I had drained 6 quarts of fluid when pan was dropped and done dripping. I replaced 5 1/2 quarts and overflowed hole. I slowly drove around the community and rechecked when fluid and tranny got warm and added another quart + bringing the total to 6 3/4 quarts of fluid.
Truck seems to shift smoother, but that may be because I babied it around after change to break in fluid.
The End... 2 hours including the watching of video and allowing tranny to drip out.
FordTechMakuloco video on YouTube was awesome.
I have 5+ quarts of fluid left to follow up again after fluid has circulated to get out more of the old fluid.
Job was fairly straight forward and easy with normal garage tools and lots of rags.
