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

[iamdub]

Well, I finally got it all back together.... BUT..... It's ticking, which I gather from the forum means it's leaking. I am not surprised. I stripped the first few threads of the driver side forward most hole. And that's not the leak. They simply will not snug up to the block. BUT THEY LOOK GREAT!!! LOL. I'm going to take it to a shop now that I can drive it...
How / who would be able to fix the stripped threads?
Should I take it to an exhaust / muffler shop, or to a engine / repair shop? Would an exhaust shop be able to get them tight, even if they have to remove and reinstall them?

I'd be concerned about why the bolts wouldn't tighten up. Are they too long? For the stripped hole, it should be an easy fix with the installation of a Heli-Coil: https://www.stanleyengineeredfastening.com/brands/optia/heli-coil

It's a pain in the ass but this helped me out greatly:

And one of these helps getting to the lower bolts:

It's easy to just take the one bolt out of the wheel liner that is level with the top of the wheel, pull back the liner reach inside and loosen the 10mm bolt and then take all the bolts out across the top of the grill, that makes it easier to remove the housing. no need to mess with the bumper at all

Well the 4L80 is not installed yet... but I decided to just go ahead and send it... here’s an 07 Tahoe spraying a 150 shot. It comes on at 3k. The trans did NOT like it...

Found out why so many people drive around in Tahoe’s with one DRL out. **** the accountant that designed this headlight setup. Threw my beer in the woods and walked away before I fire bombed my own truck.

Agreed. That's why I put an LED bulb there. Two years running, still no problem.

I have a similar issue. Mine you didn’t really hear it but felt it through the floorboard. It turned out to be a bad upper control arm bushing. For awhile I tired spraying lithium grease into it to see if that would get it to stop. It was weird cause at times it wouldn’t act up until last part of the drive and other days it was right off the bat feeling it the whole drive till you get on the interstate. Lately I have noticed the condition is gone knock on wood. Don’t know if the grease finally penetrated enough or not.

Going to have another look in the morning.

There seemed to be a flare in 2nd gear, like the band slipped. Maybe the converter flared. In any case, something wasn't happy, lol

I’m very jealous if it is
