I did a search but couldn't find my specific problem. If I drive at a steady speed on a light throttle the trans will kind of 'hunt'. It seems to be the TCC locking and unlocking every couple of seconds or so giving it the feeling that it's hunting between gears but it's not. It will do it locked down in 3rd and in o/d at a higher speed It's a 700r4 box, just rebuilt with TCI superpro kit, inc a shift kit and Jet 1/2 and 3/4 apply servos. It also has the valve that supposedly holds onto O/D longer. Any ideas?
