Hey guys, looking at changing 2002 4.6 liter S10 gear from 3.43 to 4.10. I was wondering how it affects the 4l60 that's in it? I understand the speedo will be off,but what about the characteristics of the transmission. Shift points and even the lock up of the convertor. New to computer controlled transmission. Thanks guys

 

You'd have to tune the computer for the change in gear ratio. It will cause most everything to be off because of the different gearing.
