What did you do to your NNBS GMT900 Tahoe/Yukon Today?

If anybody gives a $hit, I been using these for a few years and they are pretty good for the price. I go at least 6 months per pair. And I beat the hell out of them daily.

I use these and they have held up great in the winter with ice and snow.
Come with one refill.
Replace the blade about every 10 months.

Late to add this as I finished it last week, but with 155K, I smelled a slight coolant odor at a light, then again at another light but nothing after that. Given the mileage and the OE water pump, I figured I would do some prevent/required maintenance.

Looks like there may have been what appears to be the start of a leak into one of the mounting bolt holes.

So I went ahead and replaced the pump, hoses, T-fittings with Dorman aluminum fittings, OE pump with thermostat, as well as OE oil cooler lines, front main seal and new balancer. I did not use the plastic T- fitting in the pic. I also used the Dorman heater hose which also uses an aluminum fitting.

Didn't Project Farm test that homebrew mixture in one or more comparisons? It never did that well.

I think he did, but like most tests it's not really real life. like didn't he put bolts in threaded clear plastic and then fast rust the bolts with some chemical? or was that someone else.

either way, it's hard to reproduce 10 rusted bolts that took 10 years to get like that so you could get a good test

Yeah you mix like salt and peroxide or something

not really about the 6L80 in these trucks but we are getting to the point of 10 speed swaps being a thing. Just make sure it's "fixed" before the swap, so you don't end up worse off than a rebuilt 6 speed. I did enjoy the rant about the 8 and 10 speed issues. and over all how everything new is pretty bad these days.


I did agree with the take away of find the flaws in your vehicle and upgrade to fix those flaws over just buying new vehicles that haven't been sorted out yet.

I also agree that the new crazy amount of gears in trannys is about trying to lug the engine around at 800 rpm all the time for fuel mileage. 6 feels like enough to me.

New wipers. Trans & steering fluid sump exchange 2 weeks in a row. Brake fluid once. About 1K miles away from oil change #2 coming up on the new motor.

Has anybody removed one of these metal T’s? I know the plastic ones can be a PIA to take off, just wondering how difficult these are to remove? Maybe just use tin snips, probably a bit harder to do.

 

[j91z28d1]

wow those are new? only metal ones id seems is the crazy price ones that need like 15 clamps.

I'd buy these.
