So I went in a different direction today. A friend is having transmission troubles with his car and in an effort to help, I torn down one of my spare transmissions. It's another first for me and was a great learning experience. I learned that I need some better snap ring pliers, for one. I have been wanting to get a look inside one of these transmissions for a long time but have not had a good enough reason since the trans in the 77 has been fairly good all these 20 years.
