Good day sir. I ran across some of your post last night while trying to research some answers for my lq9/4l60e transmission swap. Might i ask some questions of you since you have completed the swap.

What did you have to do and swap out in order to get the 4l60e transmission and the old speedometer set up to work together?

what shift kit did you use to change the detent to work converting from 3 speed to 4 speed?

Thanks in advance

Hi...they are stock C6 rims with back space and other mods....gp

The rims...what size are they, front and back? Never seen those on a C3.
