sounds like the kick-down cable is not hooked up, or out of adj.

this is the kick-down cable at the carb.

if your running a holley or different carb the geometry is off. when you floor it it pulls the detent cable out and you have no t hrottle preasure. it's stacking the shifts. unless you set your full throttle at the end of the tp cable travel it will do this every time. i use a lokar cable. the stock plastic one will slip easy after the first time. hope this helps

i ahve a edelbrock 750 performer carb and a universal throttle and tranny kick down mount from jegs can anyone send me a picture of the correct amount of play that should be on the kickdown cable?

thanks

ive read instructiosn on how to adjsut it but when you hold it fullthrottle are you suppose to adjust the cable so that its tight on the end or are you suppose todo the oppostie and have it at the end where it slides in so there play.??

jsut al il confusedi ma newbie
