    Tranny Guru\'s need help with 700R4 shift kit ideas

    Been doing alot of looking and reading on a shift kit for my 88' 700R4. Alot of guys are saying don't put on in a 700. They say they wear out some parts of the tranny while making it shift hard. Some guys say a few select GM parts will make the difference but not harm the tranny. B&M I hear are the cheap fix. TransGo I hear are good kits, but do they do it correctly? Can I do a TransGo with the tranny installed? Help!!! Thanks guys!

    I believe most shift kits can be installed
    by just removing the pan and what not.
    I think if your tranny is working
    properly, you shouldnt need one.

    I had a mechanic do my rebuild first and
    it didnt work out so well. He ended up
    putting in a shift kit(after quite a few
    failed adjustments) and it seemed to
    help out. Then when I hooked up to my
    boat a month later, the tranny blew.

    I ended up buying a rebuilt one and installing
    it myself. Works great with no shift kit.
    Of course, I still have to recover my money from
    the cheezy mechanicccccccccccccccccccccccccccc.

    A shift kit in a tired tranny might push it over the edge.
    Hard shifts aren't really that bad. Soft shift allow too much slippage and soft apply of clutches which can cause major damage. The 1-2 shift should be really firm but not jarring. The valve body will probably need to come off to install a full shift kit so be careful.
