Good morning everybody... New member here... My daughter purchased a 2004 GT premium... I love it! LOL... I am just wondering exactly what make and model of transmission are in there... It is an automatic transmission... And then my next question was going to be at what RPM's should I be shifting? It seems the wind out a little bit the first year... Then shift and run through second-year fine... Then shift to 3rd gear and quickly shift to 4th gear... It runs third-year a little bit but it doesn't seem right... That being said the car runs fine... I don't think the average person would notice what I'm talkin about maybe but... there are some issues with these Transmissions am I correct? As opposed to Transmissions with no issues LOL... Thanks
