Thanks for everybody's reply, this gives me enough to go back to service

Thanks for the reply, do not know why this service writer is feeding me this line of info. But wanted more info before I contact service manager for more answers.

Hello, Just returned from a trip up north, in mountains of N C West Va. the DIC informed me to Service Tire Monitor System. when i returned took in to GMC for service they said nothing wrong with system it was cell tower interference. Is this a real problem?

Thanks for the reply on this topic

cant get a straight story on the difference between a PF 63 oil filter vs PF 63 e oil filter. one part tech said it was fleet pack another said their was no difference. my engine code is (D) 5.3 L84 gen 5 var 2. when I changed oil this time I had a hard time finding a PF 63 filter, but no one has a great reason why.
