I have a 727 behind a 318 in my '72 W200.

I recently swapped a 4bbl intake and carb on in place of the stock 2bbl setup. I had to extend the kickdown linkage, and now have it setup pretty well. At WOT, the linkage can't go any farther back, and under moderate throttle it hits 3rd at around 35mph.

Problem is, I have no partial throttle kickdown, or full throttle kickdown. I've read here that 71+ should have PTK?

My dad thinks it used to at least have full throttle kickdown. However, I don't remember it working before I did the carb swap.

I have receipts from '86 when it was rebuilt and had a 'Trans-go shift kit' installed. I'm guessing it's the TF-2? Would that remove PTK/FTK?

Any ideas or things I could check?

Thanks,
