Hi all,

At the advice of some here at inliners.org, I'm considering replacing my current Powerglide with either a 2004r or 700R4 instead of the TH350 that I was originally planning. I like the idea of a lower 1st gear for acceleration in conjunction with an overdrive gear. Anyway, my question is this: What mods would be required to the column shifter to accommodate the extra positions? Would I need to swap it out completely for a more modern column or can I modify the stock one? (1963 Belair sedan, for reference) With the TH350, my plan was just to lose access to L1, which was really not a big deal for me. I guess I could do the same thing with the OD transmissions, where my marked 'D' would actually be 'OD' and my 'L' would be 'D'. I'd lose access to low gears entirely, which again might not be that big of a deal. Does anybody know a more elegant solution than this?
