    4WD service light and “Limp mode”

    I had BlackBear tune it years back and he disabled the Displacement on Demand system. It’s permanent V8 mode. Thanks for trying to help though! Update in case anyone else was wondering, I ran out of all my options and broke down and had it towed to the transmission shop again. They’ve had it...

    4WD service light and “Limp mode”

    Not reduced engine power, just R and 3rd gear(s) only. I am going to scan the codes again today.. I’ll update on that shortly. The transmission shop cleared all stored codes before this started happening again though.

    4WD service light and “Limp mode”

    Hey guys, I’m having an intermittent nagging issue with the drivetrain and I just can’t seem to get to the bottom of it. First, I have a 2007 Tahoe 5.3L with the standard 4L60E trans. Sometimes when I hop in and start it, everything is fine, but half the time the CEL comes on, DIC indicates...

    2007 5.3L Harmonic Balancer/Crank Wobble

    yeah, I’m going with not.. haha To everyone else who commented, I’m very grateful. You have definitely put my my mind at ease. I think if it were shaking my steering wheel I would’ve taken it in immediately and never have posted this thread but I’m nowhere near that. I still may change the...

    2007 5.3L Harmonic Balancer/Crank Wobble

    The video doesn’t quite do it justice. In person it looks more cause for concern. If the crank is that unbalanced, I’m afraid it’s going to smoke the crank bearings. Then again, it’s got 132k on it now and I’m definitely hypercritical of everything!

    2007 5.3L Harmonic Balancer/Crank Wobble

    Hey guys, I was hoping to get your opinion on this unbalanced wobble I’m having. Truck was in a front end accident about 7 years ago when I first bought it but it was really just cosmetic damage. There was no damage to the frame or any of the parts inside the engine bay. I think they replaced...

    Sand in my HVAC system... please help

    Ok so I will preface this with the fact that sometimes I can be a complete idiot, so we can get that right out of the way first.. haha So lets get to the issue. This weekend I let the girls take my truck out to Olds hill in Glamis and everything was good until the way back. Yep, I'm sure...

    R1 Concepts Rotor/Pads install and making wheels pop!!

    Right on. It's definitely intriguing for sure because I am totally one of those anal guys you speak of that likes my stuff to look super clean. So, heavier on the vanes and around the hub, lighter where the pad touches. I think I can handle that. I think I'll give this a shot when my new stuff...

    R1 Concepts Rotor/Pads install and making wheels pop!!

    Sorry to bump an old thread but I just can't seem to wrap my head around this concept. I need to replace my front brakes soon and have been doing a lot of homework on what you guys have been putting on your trucks lately and I ended up on this thread. To me this just seems ludacris. Doesn't the...

    cylinder 1 misfire

    whelp, verdict is in.. just got it back from the dealer today. Dealer says exhaust valve in cylinder #2 is shot. 95K miles, mostly easy highway miles mind you, and I'm already looking at a $3,000 valve job. Happy New Year to me!

    What parts to upgrade internally 5.3l?

    Does anyone have a specific cam in their hoe that they really like or suggestions for a specific degree cam that works well in these engines? Again, I don't want to go race cam, just one that increases low end torque or an even power increase over the whole range.

    cylinder 1 misfire

    BB disabled my AFM and it still had the "chevy stumble" even after it was off. Justin turned up my idle 50rpms in park and 25rpms in gear and after everything we could still just sit there and watch cyl 2 misfire almost every other cycle. As soon as I accelerated off idle then the misfire goes...

    cylinder 1 misfire

    Hey Jennifer, I tried to PM you but apparently I don't have enough posts on this forum to be able to PM people. I really do appreciate you guys taking an active approach at helping us out with issues like these. I ALWAYS try to go through the dealer whenever I have issues with my GM vehicles and...

    What parts to upgrade internally 5.3l?

    Justin just disabled it when he did my tune. I can't tell you enough how much I recommend a tune from BlackBear. You get a bada$$ custom tune and your afm turned off in the process.

    What parts to upgrade internally 5.3l?

    Thank you for the response! Yeah I totally agree about too much hp. That's EXACTLY what I'm trying to avoid, doing a tranny rebuild immediately following. When you say intake do you mean an actual intake plenium or CAI. I have the volant and got a blackbear in-person tune (see sig) which...

    What parts to upgrade internally 5.3l?

    Hey guys, since I am completely out of warranty and it looks like I will be flipping the bill for rebuild soon, what are some quality internal upgrades that will give me a little more torque and hp's under the hood? I'm not looking to build a street racer, hot rod SUV. I'm just looking for some...

    cylinder 1 misfire

    I'm having this same exact issue with my 07 right now as we speak. Mine is Cyl 2. I've done plugs, wires, seafoam treatment, and had Justin from BlackBear do a custom tune to get rid of the stumbling idle/CEL problems (and of course better performance). Nothing has worked so far. Going into the...

    oil level low on message indicator?

    I know I'm just preaching to the choir here but I too have an 07 Tahoe 5.3L with this same issue. It first happened to me when I took a road trip from San Diego to Monterey. We stopped in Pismo Beach for the first night to camp on the beach and that next morning I experienced this issue for the...
