My window sticker shows
ENG: 5.3L ECOTECH3 V8 W/O AFM
Credit - NOT EQUIPPED WITH

What's the build date?

I did some research and my truck must have DFM. The 5.3 in the Custom is different than the 5.3 in the LT. The 5.3 in the LT has DFM unless specified that it does not. Mine does not show a credit so it must have DFM.

What's the build date?

4/21 - I also have the 6 Speed transmission

I believe that all the new v8s have the 10speed I know the custom and the Lt both do

The Custom Trailboss with the 5.3 only comes with a 6 speed forward gear box in Canada, to get the 10speed forward you need to move up to the LT TB, again thou this is what it is in Canada.

email socialmedia @ gm.com ask for your build sheet - it lists every RPO (even those not shown when you scan the QR code in the door)
Mine had the YK9 code (be sure to provide them your VIN in the email)

I have a 2019 TB LT Z71 and would like to know if anyone can tell me if there is a fool proof way to determine if my truck is equipped with DFM

I got a copy of my build sheet from the dealer and it states it there and it aLeo has it on my window sticker. My truck is a 2022, not sure it will be the same for a 2019, but I would think on the build sheet for sure.

Thanks. I went back and found it on my window decal.
