just start in 1st
 

hey npwrestler, i have a 1994 mustang gt that i had 3.73's installed in. my car also neutraled-out off the line. someone on here posted that he read in a magazing article that anything lower than 3.55's(numerically higher)would make too much line pressure, and it would neutral-out off the line. the way to fix it is to get a chip, or do what i do which is manually shift starting in first.
