AT floor shifter
I'm installing bucket seats and auto trans console in a 1962 full sized Pontiac. How do I figure out where to bolt the shifter to the floor? It has a shift rod and not a cable and the rod has no adjustment.

Maybe I am dumb, but it a AT shifter is bolted to the floor and uses rods, how can that be?
How can it deal with the trans rocking some as it does? With rods I would thank that like a manual trans the shifter would bolt to the trans.

Maybe that's why they don't do it anymore.

It might be a little hard to see but here’s a couple of pictures of the factory 2-speed automatic console lower shift rod on my 1964 Le Mans convertible. The lower rod is adjustable for length.
It has a rubber bushing that the adjustable end rides in, any movement of the drivetrain is absorbed by the bushing plus the adjustable end that has a built in pivot. The rod can pivot inside the adjustable sleeve so it’s not solidly attached to the adjuster. Of course they’re assuming your motor and transmission mounts aren’t worn out. The shifter itself bolts to the top of the transmission tunnel. There is a short curved rod that goes from the shifter to a belcrank that pivots on a bracket that bolts to the underside of the floor. From there the straight adjustable lower rod attaches to the shift lever on the side of the transmission, in the same position as a TH350 or TH400. I’m running a TH350 and the linkage hooks up directly with no modifications just like it did on the original ST-300 2-speed.

It was pretty common in the 60's to have a shifter with rods that bolted to the floor both auto and 4 speed. That's a reason why gears were missed with the 4 speeds and hurst came along and designed a 4-speed shifter that bolted to the trans and floated in the trans tunnel hole. The oem's adopted it around the 69 model year.
To the op, seems the best route would be to let the rods dictate where the shifter needs to be....??? That's the most important part. Then position the console over that and let everything fall into place. |

Thanks for the picture. I think I am missing 2 pieces. I need to find a bell crank and the adjustable rod.
