If you are debating on a Diablo chip be warned. They can't seem to get the correct program for the autos. The chip will actually make the tranny slip into nuetral on WOT. This has occured in two othe 2000's as well. I had Ford run a diagnostics on the tranny and it's fine. I am awaiting an answer from Diablo. Until then I guess it's Hypertech until they can get their act together. I will let you all know my results!
P.S. It's not all GT's just the 2000GT Automatics.
