At what speeds should my C4 be shifting? I think right now it shifts from 1st to 2nd at 10mph, and 2nd to 3rd at 20mph. Is this right? If not what should it be. Thanks
that sounds about right. i have hella tall gears, it goes 1-2 @ 12mph, 2-3 @ 27. some of this depends on your gear ratios. off the top of my head, yours sound right for a 3.00 or 3.25 rear end
