That is a lot of miles, but I have a 97 Tahoe with 184,000 miles and it runs like new and I would take it anywhere. Original engine and Caitlyn Jenner. $19,000 seems high maybe you should offer them $16,000

 

themasterc- ill sell you my 03 with 89k for that price right now lol.

as of the trans - if it shifts fine without slipping hard shifts its fine. you can get a trans rebuilt online for under 2k. probably find a shop to do to it for 1500 locally. 6000 for a trans rebuild is un heard of even for a performance transmission.

 

a gm trans with 3yr/100k miles its about 2900 to 3100 ... you can get 2 with 6k$ :-) or you can get someone localy to get it done for less with a year waranty ..

 

I am "that guy" I do take care of it. oil changes every 3K, Trans and Diff service every 30k or less if I am extra hard on it. I replaced my trans at 82k or so. I had my Torque Converter fail which led to a transmission being replaced. Supercharged with mods. I Tow a Fairly heavy camper and go into the mountains at every opportunity. just fix it with o.e. or better when something breaks.

 

Mine crapped out at 132k miles. $2400 for rebuild. started feeling like I was towing a big boat every time I stopped at a light.

 

Sort of off topic. But I tow w/ mine as well ('08) I have the large tranny cooler but has the supercharger added to overheating issues while towing? I'm in AZ and we're always towing up hill at 3-4k rpms when it's 105 out.

 

My old 2003 never had any transmission issues when I sold it with about 130k miles. It ran just like day one.

As for my 2009, either the guy who owned it pushed it & it's starting to break down or the 6L80 is simply not as robust as they claim it to be. I'm missing gears, constant hard shifting, drive line clunk, etc.

 

I think we're learning that the hard shifting and drive line clunk is the norm for the 6l80 at least in the H2. I've pretty much given up on trying to find a solution in my '08

 

Yeah. I'm really, really unimpressed by the 08/09 power train.
All the more reason to get a diesel. As mine rides now, I slip from third to first downshifting at times... it's not just annoying... it's just awful.

 

I'm sure if I was experiencing your issues I would feel the same. But I'm coming from a 4 speed diesel Excursion 7.3. Now I love having 6 gears and the ability to have power from 2500-4500rpm's while towing. I've thought about a diesel but I think the cost/headaches never provide a return. If I did anything I'd do the supercharged LSA. Seems like that would be a more reasonably priced option.
