Hey im getting 3.73 gears for my 95 camaro. Im being told that i need something to calibrate the speed? Help?

 

i think you can have it programed to adjust the speedo for the gear change. not completly sure though. only way to be sure is to take the speed sensor out and have a look. if its got plastic gears back there then its gona need different gears, if its got a reluctor then its computer controled and ull need to have it programed. http://www.transmissioncenter.net/sp...__va.htm#4L60E
