Hey guys. My car is an original 400 auto car, nothings been swapped or modded. My electric kickdown isn't hooked upright now. I hooked it up a while ago and works, cruising along at like 30 - 40 mph hammer the throttle and the tranny down shifts and the car pulls hard. My problem is that it doesn't seem to want to upshift as long as I still have the pedal at full throttle. It feels like it needs to as the rpms are up high and the car isn't pulling as hard. If I back of the throttle a bit it will upshift. But I should be able to just punch it and keep my foot in it and it will kick down and then upshift on its own right? Do I have to adjust the govener on the tranny? I do have a cam in the engine, could I have a vacuum problem? The tranny works fine other wise I would just like to have the kickdown functioning.
