I have a transmission that came out of a 91 Bonneville that we had but I'm not sure exactly what it can be used in?

Im assuming pretty much anything with a 3.8 from 87-91


But here's the funny part the trans came out of a bonneville but it has writing on it that says "1990 chevy celebrity 3.1"

So what all models or years would this work for? Also I'm pretty sure that the gear ratio would have to be determined on the car and the tranny to make sure it would work. Correct?
