so i put a new kickdown cable on my small block 350 but there are some problems. the car doesn't want to shift, it will rev all the way up to 4000 RPMs before it shifts, and even then it shifts hard. after it shifts i can play with the throttle and there is no response, it just revvs until i press the throttle to 4000 RPMS then it catches. this did not occur before i put the new cable on. so i dont think the tranny is having problems. any ideas?
