Transmission question

If you are old enough to make babies and have experience in that task, then you can rebuild that trans yourself. It's only scary the first time, and once you get 'er done, you'll be wondering why you were ever scared to open her up.
Once the pan is off, you can make a decision about the TC based on what you find in the pan.
Or if you are really nervous, you can take it down, clean it, strip it, replace what needs be, and then hire that high-priced shop to slam it together for you. BadaBOOM!
