I was unaware of that, thanks for updating me.

Well, before I bought new TPMS sensors I'd test the batteries, or the heck with it; just put new sensors in with KNOW GOOD BATTERIES, dont just trust batteries just because they are new to you.

Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's manual. ChatGTP will b e a faster, better help than Google.

Prolly diaphragm bellows rotted out. Given the age of your truck.

My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

Our local Ace Hardware made a chip key for my 2015 Silverado for$100.00; that's a lot less than the dealer. I suggest you give them a call and have your VIN,title, and/or registration with you.

Call an auto recycler, t g ey zhoukd have an interchange data base. The data base goes WAY back and is an urreplaceable asset.

How come there's no Avalanche Forum?

I would look at the part numbers of the dashe's wiring harness. GM might used the same harness for all trucks or considering the cost of copper they may not. A GM district rep might know. Call chevy customer service, 1 800 222 1020 (I think) they have been very helpful to me in rhe past.

Go to local Ace hardware, they can fix you up with a key and programming. I paid 100.00 for a programmed key. best price around.

Got an 06 1500 LTZ Avalanche. It needs a fuel pump, which one is the best? TIA

My brother '99? C2500 Heavy 7.4 automatic; speedo is weird. Pls. see attached video. I think it's the sending unit. Doug

Replace the oil pressure sensor. If you ever worked on a small block tou know where it's located, get a GM sensor.

The 4 X 4 was engaged while the truck was in the body shop, most likely when they cleaned (almost detailed!!!) the truck for delivery. Thanks for the response!!@
