I had transmission replaced in my '16 Sierra earlier this year. 5k miles on it and its starting to shit bricks again. I decided to take advantage of high prices of used market now and traded it in for a ZR2 Silverado. I'll miss it. I loved it, but I think I'll love my ZR2 more. Paid just under MSRP for it, not a great deal but acceptable because most dealers mark up these. Gave me $28k for the old Sierra with 90k on it.
I nearly bought a Ram Power Wagon last weekend until the dealership added some bullshit at the backend and $3k+ of fees. Walked away. Glad I did, the ZR2 is a way better truck for me. It is freaking fast. I like fast.
Already did some things to it:
First modification - antenna delete
Bakflip X4 from old sierra (it was 1" too short, I have a couple holes in the corners I need to figure out gaskets - don't really want to buy a new top)
Bedrug
Planned mods:
Tint all windows - factory tint too light.
dashcam
6 way lights at high beam (all forward facing lights on same time at high beam)
auto fogs (fogs on when low beams are on)
cargo lights to come on same time as reverse lights
Ultimate9 Throttle Controller
disable auto start/stop
