01 Yukon XL 331130. Other than having to rebuild the 4L60E and a bit of rust behind the passenger rear door, it is in great shape for it's age/mileage.

My 07 Tahoe LTZ has 190,000 miles on it with the original 5.3 engine and original transmission. I am curious how many miles are on everyone else's vehicles and if they still have original equipment.
I’ve had a mystery oil leak for the last 20k miles... just replaced the valve cover gaskets to see it that was it...
Nice!
I have an 07 Tahoe LTZ 4x4 but with 282k miles - original everything. I’ll easily hit 300k this year as I commute 900 miles a week for work. Normal maintenance performed regularly. I’ll be replacing the wheel bearings later this week. Other than that, a quart of oil in-between changes keeps her happy.
Did you hit 300k yet?![]()
292,000 miles on my 5.3L 2007 Suburban LTZ. The engine runs great. Compression is great. I resolved the oil consumption issue so I don't have to add a quart every 1500 miles now.
Transmission was rebuilt at 202,000 miles. My wife broke the forward sprag in it. She has a really bad habit of putting it in drive while still rolling backwards then slamming on the gas. I kept telling her it was going to break the transmission but she didn't believe me. The 4l60e is is a bit slow fully engaging drive after shifting from reverse. I rebuilt it myself and the internals were in perfect condition. Everything was well within spec and I have no doubts it would have gone 500,000+ miles no problem. I could have replaced the sprag assembly and put it back together as is but I did a full rebuild with all new steels and clutch packs. Also did some other upgrades so it's a 4l60e/4l65e hybrid.
What did you do with the oil consumption... I am down 2 quarts every 3000 or so miles...
