I can't seem a "start to finish" post anywhere showing how to adapt a column shift linkage to a 4L80E. Any links to a post or any advice would be appreciated.
4L80E with column shift...has anyone done this?

Do you have a column for a 3speed auto or a 4speed auto? Either way I can't imagine it being any different than a 700r4 maybe even a 200r4 also. There a cutlass in my Friday route ls1 4l60. It has a 3speed column shift. On that car you just can't put all the way in first gear. 1 on the column is actually 2 on the trans. 2 on the column is 3 (or drive) in the trans. And d is overdrive.
The 4L80E is electronically shifted from gears 1-3. You could use a lokar shift adapter cable for your column but remember that you can only manually shift from Park to Drive.
this may help i did it with a th350 watch this video starting at 4:40 and then watch the next video part 9 i think i perfected it more in part 9.
Thanks for the replies. Regalman, did you solve the 1 -> 2 shift bind? I don't think I can live with that "clunk". Would drive me crazy. My column is the 3-speed style, but I'm not sure that will matter. I wonder if I can modify the "cable column" shift style linkage and fabricate a bracket to hold the column end to the firewall? I see that factory bracket that clamps to the end of the column sure won't work.
It seems nobody that I could find has "perfected" the swap (ie. shift points hitting the correct position on the indicator, not hitting headers, etc)

I plan on pulling the 307 out of the Cutlass next week. I think I am going to put the transmission in the car without the engine and see if I can devise a linkage setup. I think not have the engine bolted to the transmission would make it easier to fabricate.
Yes if you watch the next video in the series part 9 I believe that is where I perfected the shifts it was a matter of taking half an inch off the linkage bar. I ran it all summer and drag races it 3 or 4 times no problems
That picture you just posted that is definitely not a G body firewall
Nice Regal James. I've been following your thread on LS1Tech. You have the same problem I do....no traction.
What is your best time at the track? You should be in the 10's with that set up.
Yeah, I realize it's not a G-body. I found it on a classic truck site. I think I can rig something up that's similar. If you tweaked yours and got it right, I guess I might just go that route.
