    Ok, i would really dig a TH-700 because of the improved gas milage. I may have access to one from a 2wd pickup(85 silverado) My question is, will this bolt in plave of the TH350 i have now in my 73 blazer. My t-case is an NP203. And i already know about the reliability issues of the 700 when put work.

    yes it can be done, you'll have to change the output shaft of the tranny and then get an adaptor, advanced adaptors has everyting you need.

    If you currently have a TH350 all you need is to put a 4wd output shaft in and use the same adaptor as the TH350. You will have to move the crossmember back and may need to shorten your rear driveshaft and lenghten the front depending on much travel you currently have.

    If you didn't build it yourself, how can you call it yours.......?

    3rd that, change the output shaft/housing, get new adapter, modify driveshafts (mild lift can help the rear shaft fit without shortening I think).

    Also, try to avoid a 700r4 from before '86/'87, unless it's been rebuilt to newer specs. Supposedly, there were lots of bugs in the originals that didn't really get worked out until '86/'87.

    Good luck! Hang on to the 350!

    Your original adaptor should work, if you use the correct output shaft on the 700. Considering you have to change it from the 2wd one anyway.

    Word of caution before you go this route...check to see if the 700 has a six bolt dust cover (should look just like your TH 350, covers the torque convertor/flywheel). These were designed for 4 wheel drives. The other type (4 bolt) will work but are a little weaker and may crack.
