Hi i have a jap spec tt auto
My supra will no longer go over 120mph anymore! I cant understand it. I have had it faster than this before and now whenever it hits 120mph it backs off and wont do anymore! I repeatedly tried this 4 times last night and every time the same thing happened at exactly 120mph!
It makes absolutely no sense to me. Its like its limited itself or something. Or its not getting into the final gear??? I dont know, i cant really tell what it is.
I know its rare to do such speeds, as you dont always have a safe place to do them, however i would like to think it could do it. Its just annoying me so much.
I have the overdrive ON, (button clicked in) so there is no light on the dash and it should be getting into the higher gears just to clarify.
All the rest of the time the car is 100% smooth, and never has problems doing anything i ask of it at any other speed??
Any ideas??
