automatic 727 modified / shifting issue?
I have a recently rebuilt and lightly modified 727 automatic transmission that was done by a guy that is professional and takes his time to rebuild the trannys . he put in kevlar bands and a racing shift kit. I have a factory kick down linkage on my 4 barrel edelbrock 600 carb . carb sits on an edelbrock performer intake and has the edelbrock chrysler trottle braket as well. my issue is that it down shifts at low speeds when I have to go around vehicles ect but at higher speeds like on a highway or interstate it wont down shift to pass a vehicle and have to manually shift it into second gear ? . I did like what someone suggested by having tthe vehicle off and in park and have somone press the gas pedal to the floor and I made the adjustment so the linkage pushes the linkage on the side of the transmission all the way back but it still does the same thing ??? is it because of the racing shift kit??
