ShockTherapy Posted October 23, 2005 Report Posted October 23, 2005 fuck around with the TV cable, or buy an adjustable vacuum modulator Quote
digitaloutsider Posted October 23, 2005 Report Posted October 23, 2005 It's a 3.4. The 4T60e is electronic and has no TV indent cable. Shift points are controlled by the PCM. Shift pressure is controlled by a vacuum modulator. Quote

birdman Posted October 23, 2005 Author Report Posted October 23, 2005 so the only way to get it to downshift quicker is by reprogramming the ecm?? im ok with the shift points and the shift firmness just not the point at which it downshifts. Quote
