91 teg has a cable transmission, (your engine is a b18a), so i fyou want a tranny make sure its a b series cable trany.

I know Qualif make 6 speeds for b18b's (hydrolic), and i also know they cost like $15,000. making ur auto into a 5 speed is not that difficult. These cars are pritty strait forward, so You'll have no problems. Now if you where making a 5 speed into auto, you have to change the ECU as well as some other stuff. But i dont think you'll have to worry about that.

anyhow Welcome to the board.

my advice, get a manual. Technical info on these cars are hard to get on forums. I havent done the swap myself, but i did rebuild my b18b tranny myself. And I could not get any technical info on this (or any other) forum. good luck.
