What year, car and auto/manual PCM did you get? Have you been able to check that it will work yet?
On that trans pan, if you get in a real bind, I could help you cut it and weld it up like I had to with mine. Also, not sure if it helps but you could have my old pan for shipping cost to see if it would work with some effort? I dont know if you read my build thread but it warped too much for me to use. I didnt put any effort into stretching it back out though.
