Well i didnt do it. But i had the J-mod done. To whom that do not know what this is, its a modification to the seperator plate on the valve body where u drill some holes out and mess with the accumilator springs. Good thing i did it to, i figured maybe the previous owner had changed the tranny fluid before but no it was still the same fluid at 61k so got that taken care of. Still no manual but tire barks and a lil throw back is much nicer.
