Speaking of fluid changes... those who have changed trans fluid, is it really as much of a pain in the ass as it seems or is it more just a mess? Id like to do it before roadtripping it a good 2k or so
when I did my first change after getting it at 135k. my t case magnet scared me lol. fluid was black water. rear end had more metal than I've seen on a magnetic before and I've taken apart rear ends that whine so bad you hear them 2 cars away haha.
I'm surprised the t case works, not that I need 4wd for anything and the rear is quiet. the regen does put a lot of load on the coast side of the gear than normal. some extra wear could be from that.

sounds like it depends on the tranny. some you gotta pull the exhaust to get the pan down it seems.
mine was simple, drop pan, change 2 filters fill with 12qt. but I have a 2ML70. it's odd lol
When I did the front diff I expected to find metal for sure but it still looked like brand new oil I was very surprised. I anticipate finding some silt at least, when I put the girdle on it there was very little of anything a couple years ago so that was about 25-30k agoWith the way you drive, it'd be a surprise to NOT find anything!
Added a little imagery to the dash in the 2012 to remind us of our Colorado home. Thanks @swathdiver for the idea and the pointer.

If you have a buddy with a long prybar, it's easy to drop the pan on the 6L80; no need to undo any exhaust stuff.

installed what is hopefully the 220amp alternator. (13536552) The wire plug and alternator cable are in slightly different spots. Alt cable was on back, now on top. Slightly larger stud, old eyelet fits perfectly though. The new wire plug has 6 slots when the old one had 4, but they line up and it snaps in like it should.
left new (20k miles), right old (200k?)
had to notch bottom of cable boot to get it up over the stud. Will hopefully get the right boot when i upgrade the cable..
engine cover sits down, just had it up for photo. only hiccup was easing one mounting bushing forward so I could slide alternator in, found the parts to make a puller..
Thanks Doubelieve for the 220amp tip! And.. thanks to the BEST forum!

Emptied catch can for first time since installing this new one just over a month ago and got about half a shot glass out of it.

I did mine this evening. It wasn't so plug-and-play as I thought. If it was, it would've been a 20-minute job. Took every bit of two hours. I got the 13534128. I don't know the differences in yours and mine, but they're both listed as 220A alts. About to do a write-up in my build thread. 20 pics, so it'll have to be split up into four posts.

Weird, according to this page.. https://www.autopartsprime.com/gm/generator-assembly/oe-13534128
also this one.. https://www.gmpartsoutlet.com/p/che...3--62-LITER-Alternator/78774533/13534128.html
It shows your part number replaced by my part number. You'd think they're interchangeable.

Hey Iamdumb, I'm dumber, I did not look as closely as you!
Did Not Notice the smaller pulley, thanks for taking measurements! Glad they are very close in size. I thought the belt was a hair easier to slip on compared to the last time I put the belt on. (maybe because i had to file down some grind marks on the pulley face/lip) The AutoSync device has a manual high idle, so I'll leave it stock.
Did Not Notice the larger holes. If they were to loosen, I am guessing belt tension would pull it down, and the alternator would tend to sit down by it's own weight anyhow. I loosened the bolts, and put a prybar between case and bracket. about 2mm of movement fwiw. I don't think it will loosen.
Did Not Notice the alt cable was a tower bolted to the rear, but it sits fine on the tower so I think I will leave that as well.
dark spot on bracket is liquid wrench because the sleeve wasnt moving when i tried to just shove the alternator into place..
Good Job on the install Iamdumb!
I think our alternators are the same.
I still consider these alternators to be "drop in". Only thing really needed is the larger cable nut.

If you put a @ in front of the name as you type it, you can tag them. They’ll get a notice. As in @mikez71Did Not Notice!
