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

[89Suburban]

Yes

 

[Scrappycrow]

Got it. Thanks! Is it normal for water to enter the doors and out the drains?

You're welcome! Yes, for every vehicle that I have ever seen. No vehicle has perfectly sealed windows, door handles, or whatnot.

just ordered this bumper kit from move and lightbars. spent almost 1500, just under 900 for the bumper and the rest on light bars. think people will get out my way on Houston's highways at night? lol

throw some diode dynamics ss3 max on there aimed just right and they "might"

 

[Doubeleive]

Can anyone verify where the rear door drains are? I heard water in the door and pulled a little rubber plug but it looked more like a bumper than a drain. Also any particular reason it would start filling up outta nowhere. We got some intense rain in N.J. so might have been a one off thing. Hopefully.

drill a hole on the bottom of the doors front & rear, that way the water will just drain out no matter if you are flat/angled up or angled down

Not today but a couple weeks back upgraded sway bars front and rear to hellwig units on the 2013 K1500. Much more stable. I’m used to 2500/3500HD suspension so this is a perfect compromise.

I swapped to the H3 Motor Mounts to control the 6.2L power. The OEM style mount I put in 1 year ago had failed. Towed with it today, engine feels rock solid, no more clunking as it jumped in the mount. Idle was smooth no extra vibration felt at all.

Tried using the Tow Haul mode, boat only weighs 4,000. pounds and Tow Haul was much to aggressive for me. At one point the engine revved to 4800 RPM climbing a mild hill. No reason for that at all. I was hoping it would start to self tune if I just let it go but that did not seem to happen. Also on slowing down if I let fully off the gas the tranmission downshifted to help me slow down. Not a fan of this, I always believed Brakes are Cheap, Transmissions are costly. I see no reason for the tranny to aggressivly downshift on mild stops. In the tranny's defense I have not used tow haul and it may just take time for it to self program???

The H3 Motor mount on Amazon was $260 I think but easier to install as the heat shield is much smaller leaving room for tools to get in there. It is a robust part for sure. Funny Amazon says it only fits the Passenger side. They are wrong it fits both sides just fine.

It is a lot of money, I think the one that broke in 12 months was only $50 but I don't want to do this job ever again. Way too much work to get in there to change the mount.

the transmission grade braking feature doesn't hurt anything all it does it is hold the gear instead of downshifting, it's a nice feature and helps save the brake pads from overheating resulting in loss of brakes, it's something you will appreciate on a steep downgrade

Maybe Nick can update this advice but a friend and tranny shop owner, now retired instructed me to use the brakes to get down to proper speed and then downshift the tranny to help hold that speed. He advised clearly to avoid dropping gears in and automatc trans to slow the car down. It was his statement, brakes are cheap and trannys very costly. He said the trannys are very durable holding speed once they are in gear but vulnerable to damage when dropping it down a gear to slow the car. Once you have it in the proper gear he said no damage happens and it can hold your speed going down grades. I have followed his advice for several years now but maybe he is out of date with the newer tranny's on the market.

no, when you brake it automatically downshift then you can let off of the brake and it will/should hold the gear for a good while, unless you brake more or accelerate more
