OK, 4L80E is being built right now by a very reputable local shop (less than 1 hour away). I opted for all available hard parts except straight cut planetary set. I was told it wasn't needed at my power level and I may find the whine annoying. It will be nice to be able to walk in and look someone in the eye if there's a problem or if I need help. Now to decide on a converter manufacturer. Can't decide between ATI or PTC. Price is about the same.
