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

    Rare, but check your starter bolts, and maybe even the bolts on your torque converter

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

    I was scared about that AC belt, after reading other posts, but I've now removed and installed one with my bare hands and a ratchet on the crank bolt. It's not that bad in reality.

    E85 or regular gas?

    I wonder why there is not a single E85 pump in my entire state. https://afdc.energy.gov/fuels/ethanol-locations#/find/nearest?fuel=E85

    Oil pan skid plate install

    I bought some extra bolts, and ground a slit along the length of the threads to make a DIY tap, and just blasted them into the four existing holes to add threads. Worked like a charm.

    TPMS replacement

    Have any of you folks done it yourself? Was it easy enough to air-down, then break thet bead in just one section?

    Oil pressure issue.

    My rebuilt engine sits at 38-40psi hot, when cruising at 1400rpm. That's normal. Dropping to 20psi at a hot-idle is probably worn oil pickup o-ring, or maybe even worn cam bearings. Did you replace those bearings when you did the DoD-delete?

    GM O2 sensor

    I have new GM (denso in the box) O2s upstream/downstream, and before swapping them out I was getting a P219A (and occasionally P219B) code when I hit close to redline. BBPerformance said it was a fueling issue, but everything was new, not leaking, healthy fuel pressure. After swapping in the...

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

    Yep, one of the front guys snapped. IIRC, it was the passneger side...? There's is a pocket above the bolt hole that traps all sorts of schmoo, and rusted the bracket bolt up good. The old bolt was fused in there, and I ended up drilled out a few milimeters to the side, and tapping new...

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

    Which bolts are you talking about? My rear sway-bar bracket bolts (the 10mm) came out fine. When I replaced the front bushings a year or two ago ??? there was a mighty struggle when one on them broke. I've since dropped a bit of anti-seize on them.

    20 psi oil pressure hot idle

    Yeah, I used one of these and some oil-resistant thread locker on the two screws for the pickup tube & girdle.

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

    This sub-forum is for 2007-2014 SUVs. There is a dedicated 2015-2020 forum for yours, which may be a better place to ask.

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

    Added 1.5" leveling blocks (the round kind) to the rear, to fix the squat after adding the 5100s to the front. Ordered the wrong size rear swaybar bushings, but when I pulled out the current rears to replace and add fresh grease they looked fine compared to the fronts.

    6L80 Heat Related Symptoms

    The 6L80s are fine. Their issues come from the factory JMBX torque converter, which had a poor design. The back plate would warp over time, and the "hot spots" would shed their friction material into the fluid. This material would block critical ports, orifices, galleys, etc... They aren't...

    6L80 Heat Related Symptoms

    GMT900s (up to 2014) with the 6L80 don't have the stupid thermostat in the transmission cooler lines. It was added in the 2015s and up. Edit: part of the confusion stems from trucks - Silverados/Sierras - being updated a year before SUVs. So, a 2014 Silverado would be NNBS, but a 2014 Yukon is...
