Last year I also put in a new ram clutch like the one patrickstapler mentions. It works really well and is reasonably priced. As for doing the work yourself I had never even watched someone do this before and successfully got it done. As long as you have a good place to work on it and access to the tools you need and are mechanically inclined you can do it. With the internet and forums nowadays you can do almost anything if willing to put the time in researching, watching videos, etc. I did buy the $80 transmission lift from harbor freight and it worked just fine for my light 4 speed top loader.
