    when swapping from an old school tranny to a newer 4l80e, atleast in the 2002 4l80e I used, the gear shifter and indicator on the collumn wouldnt work, because it is the opposite throw of the older trannys, atleast it was from my old 700r4. Might be worth looking at. From what I remember, to select gears the linkage pushes the arm to shift through the gear selections, but in the 700r4, the linkage had to pull it into gear. I hope that made sense. It is no biggie though, I just used a B&M megashifter. Although when I swap a 4l80e into my cucv, I am going to try to monkey with it to see if I can get the factory collumn shifter to work right with it.
