700r4 tranny experts
Well, I got the thing outof my '72 and tried to fix iton the bench...
pulled it apart, and replaced the 3-4 clutches, noticed the 2-4 apply band was breaking on the fixed end with the peg in it...and suffered stress where the servo apply pin engaged....
I was super careful to get things back to gether right again....
noticed the seals were all in good shape, looked new in fact...the input output shaft seal looked/felt good also...
now it's back in the car, and worse than ever....no reverse, weak first, weat second....no upshift either...same symptom....
old 3-4 clutches were burnt pretty good, and thinner by fair amount...replaced two of the steels also...the rest were a bit black, but ok....none had gone steel to steel yet....
remounted the brain using original gaskets....
have done that many times before....never a problem....pretty sure the checkballs are in correctly....
any ideas anyone???
BTW, New converter...

Check out the ThirdGen.org Transmissions and Drivetrain Message Board.

I've heard that you can get some good transmission advise there.
Good luck and keep us posted.
