    I was wondering. For those of you out there that have done this. I'm having problems with my overdrive (I hear a light metal clanking) when I'm cruising along and accelerate a little. Not too much to make it shift but just a bit. Things are fine if I just keep it in drive but OD you can definately tell. My question is...How difficult is it to rebuild a 700R? Supposing I wanted to put the best components in it...like the flywheel and pressure plate...and a better piston...oh...and a shift kit.

    If you've got time, space, tools, and the money, no reason not to do it yourself. I did 350's and 400's before i tackled my first OD tranny (200-4r) because I was scared what everyone said about how hard OD trannies were and such. No big deal, just a few more parts. Nothing real complex about disassemble/reassemble, just some specialized tools make it easier. Personally, making friends at a local tranny shop is cheaper than buying the tools : )

    Its not bad, just be sure to keep everything clean and remember what order everything came out.

    Will work for beer, parts and tools.
