Hey guys- just got that 2018 Silverado I was looking for. Just scored some of those stylish '21+ 18 inchers and can't seem to get the TPMS relearn to recognize the new units. Can the newer 433mhz units work on a truck originally equipped with the 315mhz units?
TIA

 

I do not believe so. I think you are going to have to put in your old sensors.

 

what I was afraid of.......

 

Well some good news here, guys. Figured I'd go to the dealer just for kicks and surprisingly the service writer actually comprehended what I was saying and told me to bring the truck by later in the afternoon and lo and behold a tech comes out with his magic wand and now all TPMSs communicate and I can see my tire pressures.........

 

Very nice

 

Yeah- ain't technology great?

 

Hope that is sarcasm

 

A double edged sword, certainly..........
