2002 impala and 1997 gtp transmission swap

https://www.gearvendors.com/cgdrive.html .and http://auto.howstuffworks.com/gears.htm ...Those websites explain it better than I can. But bottom line is if everything bolts up and works you will be fine, just a slightly different top speed, slower but better acceleration since the final drive is slower= more torque available, but it's only 0.12 turns of the driveshaft different

Thank you for the response. I am aware as to what the gear ratio would do as far as driveability but I was warned that this would affect my computer negatively since it is not setup for this ratio and that it would also affect my speedometer. Would the different sensors in the transmission make up for this?

Owww... ya got me there. I would think so but don't know that for fact
