Transmission questions. Manual valve body?

Thanks for your input. I'm installing a Lokar kick down cable to hopefully remendy the issue. I don't know if this applies, but I'm changing out the carb to a holley sniper and asked the shop that's doing the work to aquire the correct linkage. I'm confident that they'll help me get it all sorted out.
Sniper EFI ? If so you're gonna love it once you get it tuned. Lokar cable will be nice, actually anything you can install and get calibrated properly will be a great improvement. The old torqueflights were all hydruacily modulated as were many other trans of the day, well at least Fords, and old TH350's and there counter parts of GM and many others including TH700's and 200's 3 spds and OD's. I forgot to mention the differences between 2 barrel and 4 barrel throttle and kickdown linkages on old MOPARS, there is a difference from about every model of body style and engine trans combo and there are a lot of year model changes too. But Lokar with proper brackets should solve your issues.
