I had to put in a new tranny a while back (woulda went manual if I had the time :-/ ) and the tranny I had put in was from a 95 Grand Prix. My question is if there is any difference like in the gear ratios (and if yes, what is good or bad about that, since i dont really know how different gear ratios make that much difference :-)) After having the new trans in it feels like it shifts at different places, being somewhat better like for racing or whatever. I was just kinda curious if anyone knew anything to this.

 

(i don't know what submodel the GP was because I never got to see the body it was from, but it was obviously from an 3.4)

the 3.1 use a 3.33 gear ratio and the 3.4 has a 3.43 ratio, so there will be a difference in shifting
