My tcs light comes on after a while of driving but for some reason around when the light comes on seems trans won't shift to od when light off rpm around 2k around 60mph and light on rpm at 3k at 60mph has anyone ever had this problem

 

Yes, but only when I spin and it is random. After a while tcs (asr in my Z28) will go back out and all is normal. Happened after a tune. When I figure it out I will post my findings. Good luck.

 

Mine don't do when I spin when I'm driving normal

 

Still having problem with tcs light come on somtimes and go off I caint find what it is
