Psych0matt Posted June 8, 2004 Report Share Posted June 8, 2004 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) Quote Link to comment Share on other sites More sharing options...
cutlassdude96 Posted June 9, 2004 Report Share Posted June 9, 2004 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 Quote Link to comment Share on other sites More sharing options...
