Currently have a 1995 Chevy Tahoe with blown engine and trans, Just purchases a 2004 GMC Yukon with a 5.3. Hoping to use the complete drive train out of the donor truck. I will be using everything possible from it. I own a performance shop and do a lot of tuning and chassis work. This will be my 1st swap of this kind since I'm technically a ford guy.

1st question is will the 5.3 fit with all the original accessories attached to it? Hoping so. not looking to do any performance mods except a tune.

I will have to incorporate the 4x4 controls since my old trans is a manual shift for 4wd and the 04 is push button.

Both trans are a 4l80 so hoping that part will be a direct bolt in.

any tips and tricks are appreciated, I will be updating as often as I can on the build progress.
Engine is currently apart and being freshened up, hopefully have it back in the next week or so.
