Hello again,

This question goes hand in hand with my others concerning the rear end gears and milieage. Can someone explain what is behind the "hi performance" transmission rebuild kits? Also, is it more beneficial to have someone rebuild my old trans, or swap out with a rebuild "hi performance" trans. I still want to keep with the 700R4. I have heard a lot of folks diss this trans, but the more knowledgeable folks have only good things to say about it. I like the way it shifts and feels even in its stock state.

My shop buddy who does the heavy duty stuff for me frowns at the shift lever kits...says they don't do much of anything I couldn't do with the shifter that's already there. So maybe a little info on these would be helpful.

7004R is a marvelous machine. Gets a bad rap since people try to 'tune' it by ear like they are used to doing on the old hydro, TH350 and TH400 trannys. Result is a short run life before it dies. You MUST follow specific procedures to set up the TV control but done properly, can't beat the unit.

I would go either way - reputable rebuilder or reputable after-market unit. Shop around for best price on a QUALITY, warrantied rebuild. Shift kits are a good idea in any auto tranny. Factory designed in smooth, soft shifts for ma' and pa' to a fault. A shift kit firms up the shifts for a more efficient, longer lasting tranny with little or no added discomfort in shift feel.
