Kick-Down Foot Switch

[sc400InTraining]

currently in the process of trouble shooting some transmission problems (atleast i think they are transmission related)

first off I had problems with driving forward or reverse in the morning, I solved that later down the line my throttle cable was basically to cold to close all the way then later I started noticing that the kick-down foot switch (gas pedal) wasnt letting me press as easily and whenever I hit more then 60 m.p.h. and let of the gas I hear this loud almost growling sound and cant tell where its coming from my theory is just that it might be the transmission but I don't know for sure. Im currently trying to come up with some tests to troubleshoot and if I solve the problem Ill post about it.However if anyone has any leads please reply.
