My 2004 Mach 1 with the 4R70W auto tranny is not shifting "crisp" like it used to at the track on the 2-3 shift. I use a 125 hp nitrous shot with the diablo predator and I have the shift firmness set to max and the torque modulation set to none. The car shifts great on the 1-2 (instantaneous) but the 2-3 is dragging out (like 1-2 seconds). The car sometimes does the same thing on the stock tune (on the street) as well.
I'm looking for a temporary fix (to get me through WFC) until I can order a better tranny from FTTP. Any suggestions would be appreciated.
