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

    Replaced oil pan gasket, upper and lower ball joints, front shocks, torsion keys, rear springs and I attempted to replace my rear shocks but the rough country kit I got didn't work! The aluminum insert didn't fit into the bushings. Also I still see oil leaking, but it's coming from somewhere...

    Trans Question - Rough shift 1st and 2nd gear

    Yes that is exactly what I've noticed. Slow speed driving first gear is clunky and it revs out. 2-4 is smooth as butter. I'm almost wondering if it's as others have said, that the first gear is designed that way as I notice the torque and get-up-and-go is quickest in first gear. If I punch it...

    OEM Suspension?

    I don't want nivomat replacements, I just want an OE suspension setup that came on the Yukons that is cheaper than the bilsteins... if that makes sense. I've had bilsteins on my cars before and I love them, but I want this truck to be a budget build because I need it for work.

    OEM Suspension?

    I'm looking to replace the aftermarket suspension on my 03 Yukon as they a little sagged and soft. I want to lift her between 1-3 inches. My only gripe is I have a ton of parts I've had to buy to replace all the wear and tear and I don't feel like spending $600+ for a leveling kit and Bilstein...

    Hitting The Big 200,000 Mile Service

    Mine is at 198k and I have to do all the suspension components, and 1 bad wheel bearing. I still need to flush the trans, and replace the oil. I would honestly get under her with a light and go through everything. Besides fluid flushes (Oil, trans) I would inspect the brake fluid, coolant and...

    Trans Question - Rough shift 1st and 2nd gear

    I finally got under the truck today to take a peek at everything. I also have been driving her the past few days and the transmission does the hard shifting intermittently. Sometimes it shifts rough and sometimes it shifts smooth as butter. No leakage from what I saw. To start, I want to do a...

    Dying on idle.

    Any codes? Sounds like it could be plugs (just from a generic car guy perspective) the Yukon pros will probably have more specific advice.

    Trans Question - Rough shift 1st and 2nd gear

    It does. Stock height is 77". The shocks on the back are blue, I don't know if that's the standard colour. So does that mean what my transmission is doing is normal?

    Trans Question - Rough shift 1st and 2nd gear

    Okay I attached the little card that's in the glove box. I have to decipher it. In terms of the ride, I measured 33 1/4" between the rear fender and the ground, 32 7/8" from the front fender to the ground and approx 70" tall to the roof, not the rack.

    Trans Question - Rough shift 1st and 2nd gear

    Yes, just like that. I'll check that out tonight and report back. Also my eyes aren't warm to these trucks yet, but does my suspension look sagged? Sent from my Pixel 2 using Tapatalk

    Trans Question - Rough shift 1st and 2nd gear

    Thank you! I feel like I got a good one (don't wanna jinx it!) but the A/C blows cold, she starts right up and is comfy so I'm a happy camper!

    Trans Question - Rough shift 1st and 2nd gear

    It'll hang high in the revs, and then shift and it's a bit clunky. I just drove it today and it was a lot smoother so I'm not too sure. The previous owner had the truck for less than 1k miles so if someone did do it, it would have been a few years ago. Once I get my tags I'm going to her up...

    Trans Question - Rough shift 1st and 2nd gear

    Hi all! I just bought an 03 Yukon 5.3L RWD with 198K miles on it. I feel like i got a pretty clean truck and I'm happy with it. I'm also a perfectionist who has an overactive butt dyno that thinks every like squeak, clunk or boom is the car about to explode. So I've noticed that the trucks...
