Shift Kit and Power Valve
I hope for some help in this area. When I install a Diablo Sport Trans. Power Valve do I need a Transgo Shift Kit or both and must I have my Diablo chip sent back to be adjusted. My son did the shift kit and he never had his chip adjusted but I think he set the shift kif in the middle range for firmness.I has made a big differance to his shifting . I will be installing it on a 1998 F-250 LD 5.4 E4OD trans.:santa:
