I have the tr6060 gt500 version in my '05 GT... with 4.10's I shift out of first at 40mph!
Is this similar to what ya'll are experiencing; seeing as though they are designed to be building boost (I am N/A)... suggestions...??
Does anyone know what 4.56 or 4.88's at what speed, about, would I then make the shift to second ????
