Thank you! I newer found anibody that was shure for the 3 gears on the trans-am, that means it makes that sound when shifting into overdrive? That means that somethimes in kick down it stays in third up to 112.5mph at 4000rpm! wild! do your th400 's do any noise wen going into overdrive at 90-100mph?
