2G Needing some general information about transmissions.

[Broken 2G]

I am replacing the transmission in my 1998 Mitsubishi Eclipse Spyder GS (Automatic). I bought a used transmission from an acquaintance. He told me that it came out of a 1999 Eclipse Spyder GS, but I'm not so sure. The transmission in my car currently has the transmission code "F4A23", while the one I bought is stamped "F4A22". The only information I could find online about the F4A22 said that it came in earlier FWD Automatic DSMs, as well as Galants and a few other cars. I guess what I'm asking is first.. am I going to have any issues running this transmission? Secondly, I'd love to see a list of transmission codes and the vehicles they came in, if such a list exists. Thanks in advance for any help!

Thank you. If I'm reading the page correctly, I don't think I will be able to use my donor transmission after all. Maybe I need to contact the person I purchased it from. He told me it came out of his '99 4G64 Spyder when his timing belt broke.
