I just got back from a drive, ten take off's on the floor and twelve times at highway speed and stepped on the kick down from 55 - 65 - 70 - 75 and 80 MPH, I know that is 5 times but the rest were because I was having fun. I experienced no problems what so ever.
iamfink2 - does it de-rate the throttle anytime you hit the kick down switch? Like from a stand still or just when you are at highway speed? The best way for Mr. Boulekos to know what is happening is info, also look on the part and get the number on the tag that is attached to the cable. I sure am sorry bud, I am usually the "one in a million" that gets the whatever that doesn't work correctly.
