I posted about this sometime ago and thought I'd toss out another in case there's more to be learned. I have a '63 727 button shift and these earlier year TF trans didn't have downshifting capability unless flooring the pedal that came out in later TF's. There are kits available to make a conversion to obtain 2-3 downshift at around half throttle. Wondering if those having done this have any tips pro or con? Thanks.
