04 GM pick ups had 8 speed transmissions?
No idea. The Chevy Shake articles all cite 2015 to 2020 (on some vehicles). Caddy, Yukon, Silverado were mentioned. The transmissions noted were GM 8L90 and GM8L45. The thing is... not every vehicle had the problem! So...who knows. Maybe it's a combination of weird stuff. I do know that the gorgeous 2018 HighCountry Silverado WE test drove shook really bad. We couldn't wait to get out of it. When we got back to the dealership I told the service manager about it so he could get it checked out fast. It had just come in...so hadn't been thoroughly checked out yet.
My 2004 has it's own idiosyncrasies. It has multiple personalities. It's been on a repair binge for the last few years. Hence...it's a "restoration project". LOL! STILL getting a new vehicle though. Maybe a little competition will settle it down.
DH used to laugh at me for saying the truck had a mind of it's own and was listening. The day before the transmission went out I said "This thing is running like a champion!! Hope the trans doesn't go out." He said..."What were you thinking!!!" Heck...even our tech and auto friends have advised to keep quiet around it".
