I started last night at about 8pm. It took until roughly 4am to finish. To say the least, I ran into a couple issues. All is good now though - she drives wonderfully. No more vibration under load, and the new transmission oil (Royal Purple) is doing WONDERFUL things. I have yet to try the transmission oil out in the cold though - I'll update sometime after Friday with cold weather info (high in the 40s).
Next step on the To-Do List: check timing and clean out cam followers. Following that will be replacing the out CV boot on at least the passenger side - I'll need to inspect the other as well.
A surprise item has also been added to the list unfortunately: gas tank filler neck. I took her to the gas station yesterday, before heading to the shop, and when I opened the gas cap door, it just fell right off. There's $130 down the hole.
