PCS controller seems to list 1000-1500
Compushift says starting at 1034.00, but I believe I recently viewed a webpage listing more than double that price for the NAG1 variant.
I have not tracked down the price for the ofgear.dk unit.
Supposedly, Holley is working on including Nag1 support with their dominator efi system, but I have been unable to get anyone from the tech support line to answer the phone, and their web page does not currently list any such device. I have come across a couple others in the development phase, but no one seems to have this market segment covered at this time. I am going to muddle thru with a hotrod harness from hotwire automotive and the factory TCM for the time being.if it doesn't work well enough, or I kill the transmission, I will end up going with a 4l80E.
