I have no idea whether or not you can get a tranny swap done at a shop or not. I would bet that you can, it would just be very expensive. If you have the know how, you would be better served to get a manual tranny from a junked car and install it yourself. I think it would take a very long time to recoup the cost of having someone else do it for you, even if you were to save a lot of gas.
