My 2007 Tahoe LTZ still runs great but the mileage(260k) is getting up there and I wanna upgrade to either a 6.0 or 6.2 and upgrade tranny to either 4l80e or 6l80e. What do you guys think the drivetrain is worth? Engine had new lifters and oil pump put on about 100k ago. Still burns oil with AFM tuned out. What do you guys think?
