im in the middle of my lt1 swap, and im running the 4l60e tranny. I believe the tranny uses an electronic speedo, correct me if im wrong, so if that is the case, what do i have to do to swap my car over to that? my orignal set up was a 305 tpi with 700r4

thanks for the help!

 

i have the same problem. i swaped out my 305 and 700r4 in my 89 rs for a lt1 and 4l60e. everything works great but i have no speedometer either. please let me know if you figured anything out.

thanks
