What did you do to your NBS GMT800 Tahoe/Yukon Today?

[LsHart]

So i was considering dropping my oil pan today and doing new gasket, pickup tube o ring etc... and dropping my truck off next week to have the front diff gone thru and fix my 4wd.

I was searching and found a reman unit for $1250 with free shipping and now i'm debating just doing it myself and tackling the oil pan when the diff is out.
anyone heard of this website powertrainproducts . net ?

Yes, that's who I bought my block from. That's it in my pic before install

Looking for some tow mirrors.
I notice this ebay listing mentions an additional bracket to prevent vibration..

Also mentions no instructions.. Or maybe amazon is a safer bet?

Installed these on my 2003 Z71.
Purchased several years ago from Boost Auto.
On the pricey side, but no vibration.
Just wish they were level….
I think the new models may be.

The non-level mounting is what keeps me away from this style of mirror, but they all seem to be like that.

I have experimented with a few things to try to level then, but it doesn’t look right either… and sometimes introduces vibration.

FWIW..
Boost Auto does offer tow mirrors that are level, but you have to order them with electric fold… it puts the pair in $1000 territory. OUCH !

I'm hoping someone updated their mirrors to be more level.. Even if they did, there's no telling which one I'm buying since nobody specifies..
Amazon has an easy return policy if anything is terribly wrong.. But I'll see if the ebay seller responds to my questions about a warranty..

Looking because my drivers mirror has turned brown, and the adjustment moves very slowly/inconsistenly.
But also because the field of view seems small.. (My '12 Tahoe seems better, I think that notched section of mirror must be the reason..)
I'm leaning towards the older style mirror, just because it seems a little sleeker than the newer boxy style..

Also planning on a new door module, I wonder if I can get a module without power folding since most tow mirrors don't fold?

Yup, they have door modules without the powerfold mirrors. Without the powerfold there's a lighted mirror icon, without it doesn't have the icon, and the switch looks a little different.

Cool, as long is there aren't any compatability issues, I'm going with non folding switches.

I hate when I accidentally hit the button.. then have to wait and hit the button again to unfold them.
The last time I hit the button, it took like 10 seconds to fold as it adjusted the mirror glass back and forth.
For some reason it was struggling, but finally folded..

No compatibility issues at all. I went from standard mirrors to powerful. Swapped modules and everything still worked as it should. You can still use your original module if you just unplug the mirrors from it. That should stop the powerfold from working--iirc--Unless you have the led signals in it, I'm not sure if those would still work or not.

Throttle body woes.

After 5 1/2 hours driving, a reduced power mode occurred limiting speed to about 35mph while on the freeway. I took the first possible exit with the engine light leading the way. Checked for codes, only P2101. Rare for a 2004 Tahoe said the code reader, but it offered a possible solution. Disconnect battery for 5 minutes, reconnect battery, turn key on for a couple minutes but do not start. Turn key off, wait and then start. Viola! Engine light gone, and engine revs freely.

Back on the freeway for two miles and P2101 returns with friends P1516, P0120, P0220. OK fine. At this point I'm 5 miles out and no longer on the freeway, limp mode it is to get to my destination.

After a cool down I tried several relearn procedures for throttle actuator, throttle pedal position and clearing module errors. No dice. Pulled the air inlet and noted butterfly was slightly open but snapped shut when touched.

Replaced throttle body unit and all is good.
