I had a 07 GT/CS Conv with the aluminum 18's...I sold it for an 08 GT...The dealer allowed me to switch the 18 from the old for the painted 17's,..no brainer...NOW the message board and indicated for the TPMS keep lighting up..My question is did the 07 have TPMS sensors in the tires, and if so what do I need to do to make the switch work...and if not are there any tricks to fool the sensors, or do i need to pony up the cash for new sensors...thnks

 

Yup need the sensors.
You can, however put them in a bag in the trunk if you want.

 

Go to your local dealer. They can match the sensors to the new car. It requires a special dealer service tool to recalibrate them.

 

get the old sensors and put in the spare tire, or just press reset and live with it. new sensors are very costly.
