Denali and Escalades have a 4l65E transmission. The express 2500/3500 vans have the 6.0 and 4l80e. I currently have an 04 escalade 6.0L that I parted out and kept the motor for myself and the transmission is from an 04 express 2500 van.
yea, that's why you cant find an LQ9 with 4l80e... unless you scrap two vehicles.
LQ4 with 4l80e is what I got. I probably have that guys info... he had quite a few low mileage motors. All he does is junk Chevy trucks. His yard was insane. Fucking mountains of wiring and brake calipers and shit
Here was one of his engine sheds: He also had some nice newer motors I couldn't afford.
