Update, First, I would like to say I traded my 2021 RST for a 2025LTZ, long story, and that's not important other than the 21 was the best truck I ever owned CCV(warranty at 40K) and oil changes 70K.
So put 1500 miles on the 2025 and check the engine light and hard shifts. codes P2817, P18AE, P0700, Brought to dealer, and yes, they say it needs the new # valvebody and software. So of course, valve body # just released Aug 15, and yes, backorder. So that's where I am now.
I will change my picture to the white 2025 soon lol.
