I called the nearest wrecking yard. They want $1600+my 5.3l for a 2003 6.0l with 6200 miles on it. Is this a little high? Is the harness connector for the 4l60e and the 4l80e the same (they looked different to me)? Which year model 4l80e should I get? They have a 2000 for $750 + my 4l60.

 

I'll get you a brand new one for $2700, maybe a bit less. No core. Complete. TB, injectors, intake to oil pan.
