RE: Transmission fluid change
Ok I am going to share what I learned from this. Yep I got it done. In trying to get the piece of metal that holds the shift cable to get out of the way to drop the pan it wouldn't bend past a certain point so I just used a C-clamp to hold it to the front wheel drive shaft. Then, and this is important, if the gasket for the filter absolutely doesn't need to be replaced then for gods sake don't because once you tear into it you HAVE to replace it. The gasket was a pain to get out because I had to apply the right amount of force on the top of the gasket but not enough to scrape the sides of the transmission. When that didn't work I took a little more drastic measure of taking a very small flat head screw driver (the kind you use for glasses) and taped on the metal part on the bottom of the gasket and started to bend the old gasket in on itself until I was able to get some needle nose in there and grab onto it and pull it out. Anyway that was my experience with it, yours may be different.
