the adjuster at the trans lever is a fine tune compromise kind of deal. one turn can be a difference between all indents of the valve body being felt & all but one type thing. since it's my car i'm always the one under the car feeling each indent so i'm used to the feel. when it was new & it wasn't right i could slip past a gear under the heat of battle. but now i've got a handle on it, every gear is positive. i've got the A&A ultimate brake valve body PN123N. it's cruicial to have it right.
