kingblp Posted July 24, 2005 Report Share Posted July 24, 2005 I have a 00 Seville SLS. I can watch the tach decrease around 45 MPH meaning that it shiftf into what I think is 3rd gear. It doesn't lower after that. Is it supposed to shift into a higher gear sometime after 45 MPH? Link to comment Share on other sites More sharing options...
