Tranny shift ?'s
I have a 4L60E with a restalled converter(3300-3500). When I would give it WOT from a stand still(Stopped position) it will only rev up to 4000 rpm. and wont shift. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> I called my pcm tunner and they blamed it on the holley intake saying it has a vaccum leak. They also pointed in the direction of the fuel filter and, or fuel pump. ANyone have any problems like this?
Thanks,
