I have a 4L60E backing an LS2 with a Speartech harness. What are you guys using for a Neutral safety switch? The car won't start in neutral and is a PITA to start in the Park position. I have adjusted my current set-up as much as it physically allows me and it's not quite there it's hit and miss. I have a shiftworks conversion gate and I am using a rod(from shiftworks) as opposed to a cable for the gear selector.
