I ordered the solenoid pack from tousley ford they had the best deal and had it in stock. I went for the 2 day shipping and it was very resonable. None of my local dealers had it in stock and they all quoted me MSRP. I did this last night in about 2 hrs, taking my time trying not to make a huge mess. I put down some plastic sheeting that made clean up a little easier. I changed the filter at the same time with the OE filter from Tousley Ford. Those guys were great. I cleared the codes and drove it today it seems to be shifting fine. My comments from changing this out are pretty much same at FordNuts, you just drop the pan, and change out the solenoid pack:
remove drain plug (13mm wrench)and drain trans, drop pan botls with 10mm socket, I also had to remove a dampener to get to the back three pan bolts. It took an 18mm to remove the nuts from dampener and get access to the back three pan bolts. I did not have to remove cross member. I do not know if the pickups have as many of these weights/dampeners as the excursions do but this one was in the way. Next remove trans filter. Expect a shower of ATF when you twist that filter and pull it off.
To remove solenoid pack: unplug connector(its on passenger side of trans), remove single 10mm nut from stud, and remaining T30 bolts then pull the solenoid pack off of trans. The single 10mm nut had fallen off and was stuck to the magnet in the bottom of my pan. Then just slap the new one in there and put it all back together. I had to add 2 gallons of ATF and I will check again after test drive. I do not know if the TC has a seperate drain plug, but my fluid was in good condition as the trans had recently been serviced. So i was not concerned with getting it all out.
Sorry this was a little long and rambling...anyway it was not bad and seems to have taken care of my issue for around $300.
