Who has high mileage Denalis (200k+)?

[optimusprime]

I’m in the process of potentially selling my rig (08 Yukon XL Denali) and getting into a 2018. However, I loathe payments and this rig has been awesome for us. I was just wondering who here has rigs with at least 200,000 on the clock and what issues i may expect to deal with after this point. Original tranny but it has a hard 2-3 shift sometimes. It’s got an upper oil pan leak so I’m not sure if that’s the cause of oil loss or if it’s the engine. It still runs amazing and I’ve never had issues with the engine itself. I may just try to doctor it up a bit and fix the big stuff as it comes along and save myself $35k+. What do you all think?

depending on what's been replaced. there's a few things that will need refreshed soon ish. if you're a diy guy, it's not horrible. bit pricey to have a shop do.

but my 2 cents is spend time researching that 2018. from my reading they seem to be pretty unreliable compared to these, if you like what you have and doing it just for reliability. it might be misplaced.

but new car fever is real haha. the new ones look nice too.

I’m pretty handy. I don’t mess with transmissions or tearing the engine apart. Everything else I’m comfortable with. I mean, even if I have to totally replace the engine and tranny, I feel I’m still ahead by around $25k. Just some of my thoughts.

Are you willing to replace/overhaul the transmission or differentials and the little things that wear out over time? I think that is preferable to a car payment. Mine is an SLT and runs great for having nearly 212K on the odometer.

I’ve got 208k on the clock. Still runs good. I just go back and forth. I hate payments and this thing has been paid off for a good while. From everything I’ve read, these older 6.2s with no AFM tend to go a long time. Not sure how long that is. The newer models tend to scare me more just with the computer stuff and newer engine things.

there's a sticky tread somewhere with some stuff to look for buying used. even thou you already own it. most of the same should apply based on how much maintenance you did.


off the top of my head, the torque converter in the tranny replaced if you haven't done it around 125k. when they go out they take the tranny. but if you haven't replaced it yet, and have a hard shift. might be signs it needs it soon and I don't know if tranny damage has been done yet or not.


*edit if you don't have afm. then oil pan gasket always leaks at some point. while there a 5$ o ring is worth doing. rear main and cover would be good to do during torque converter swap.

at that point just fix what goes bad as it happens. my 2 cents if yoh can find someone to thru a new upgraded torque converter in it for reasonable price.. keep it, fix it up and see how far it goes. I sold my 96 tahoe at 325k and it felt nice to hit 300 with it. the buyer is still driving it last I heard.
