    What is this???

    I believe that is normally a temperature sensor for the hvac controls. Sent from my iPhone using Tapatalk Pro

    Yes that is the OnStar microphone. If you are deleting OnStar, then it's a good spot to use. Sent from my iPhone using Tapatalk Pro

    4L60 to 4L80e Swap

    So far I love it! The power is a night and day difference from the stock 5.3/4L60 combo. I'm still running the stock 4L80e converter for now with a 2400 stall. Might change that later on. I lucked out and the tranny I got only had about 60k miles on it. May need a rebuild at some time, but for...

    4L60 to 4L80e Swap

    Thanks. I got this figured out about a day after my post. Been driving it around and enjoying the increased power! All the figures point to about 550hp. Still have to get it on a dyno at some point to confirm. Also plan on adding a turbo later this spring / summer. Sent from my iPhone using...

    6.0 Swap DIC Question

    So a couple of weeks ago, I finally finished installing my fully rebuilt 6.0L LQ4 with LS3 heads, custom CAM, 2014 Camaro intake/fuel injectors, shorty headers, and 4L80e transmission. I had a very reputable shop write my tune (CHenry Motorsports) for my HP Tuner, and it is running awesome! So...

    4L60 to 4L80e Swap

    Well I ended up making a custom mount using my existing cross member. I had the transmission mount from the 2000 Silverado that I used part of to make it happen. Fits in the factory position and should be much stronger than some of the others I have seen made. I also found a driveshaft at the...

    4L60 to 4L80e Swap

    I'm in the process of installing a fully rebuilt 6.0L in my 2008 Yukon. As part of this swap, I'm replacing the weak 4L60 with a 4L80e. I have the harness adapter already. With everything pulled out, I measured a length of 27" from the transfer case adapter to the edge of the bell housing on the...

    Did the Denali ever come with heated wind shield wiper fluid?

    I did call them today. The GM version is a drop in replacement for the factory one that was removed. The OD version is for aftermarket only. Since they are only about 30 minutes from my house, they said I could even go pick up one in person if I wanted to. Very nice people there! Sent from my...

    Did the Denali ever come with heated wind shield wiper fluid?

    So I stumbled across this thread tonight and just had to go look at my 2008 Yukon SLT. Sure enough, the recall has been done to my truck long before I bought it. The unit and fuse are both gone. However, I still have the button and mounting bracket installed. I was reading up on the AT-380D...

    2008 Yukon with LQ4 Engine Mod Questions

    So I am in the process of building an LQ4 6.0l block, out of my friend's 2000 Silverado 2500, for my truck. I have a couple questions that I am looking for some guidance on. Since the truck it is going into is a 2008, I know that some of the sensors are completely different or found in...

    Tuning Advice Needed

    One last question for you Justin. If I were to get the V2 or AutoCal, are they locked to a single VIN, or can they be used on other vehicles I own as well? Thanks!

    For your $250 price, is that also unlimited tunes using an HP Tuner? Or is it for a set amount? Sent from my iPhone using Tapatalk Pro

    Tuning Advice Needed

    Ok very cool. I will definitely keep this in mind when I get to that point. As of right now, it's probably going to be a month or two before I am ready to install it. How long does it take for the programming equipment to arrive after it is ordered? I get 6 days off from work every other week...

    Tuning Advice Needed

    Either option sounds like it would probably work. I don't necessarily need the ability to make the changes myself if there are unlimited tunes. I am interested in the cost of each option and the turn around time to get the flash files.

    Tuning Advice Needed

    Yes I already have a new reluctor ring on hand that will be installed on the crank. As far as tuning goes, I need something intially to get it running and driving after the engine is installed. Then probably tuned up after driving it around for a bit. I do plan to add a turbo to it later on, so...

    Tuning Advice Needed

    I Live in Michigan, and the shop that I called is out of Florida. So he made it sound like I had to have my own equipment to do the flash. This is a shop that is well known to my mechanic friend, which is why I talked to them first. I haven't found any local shops to do a tune where I live yet...

    Tuning Advice Needed

    Hey all! So I am working on building up a cast iron 6.0 LQ4 block to replace the stock 5.3 in my truck (2008 Yukon). I'm also going to be installing a 4L80E transmission at the same time. I have just about all of the parts ordered for the engine, and I'm just waiting to get the block back from...

    How many miles does your vehicle have on it?

    I have a 2008 Yukon SLT with 218k original miles on it's 5.3l. With the exception of consuming about a quart of oil between changes, it runs top notch. Sent from my iPad using Tapatalk Pro

    New TPMS Sensor Reset Help Needed

    I ended up going to the dealership today. My buddy knows one of the mechanics, so he brought out the tec2 and updated the pcm for nothing. So the dummy light is finally gone! Apparently Discount Tire is not capable to doing the full job. Thanks for the replies! Sent from my iPhone using Tapatalk

    New TPMS Sensor Reset Help Needed

    Highest pressure my tires go are 44lbs. Not sure I want to get that high of pressure in them while driving on snow an ice. Any other suggestions?

    Yukon 5.3L to 6.0L Mod & Swap Help

    I posted on here a couple of months ago in regards to some mods that I wanted to make to my truck. As a refresher, I have a 2008 Yukon SLT with the 5.3L. After talking to my buddy, who is a retired GM mechanic, we have decided to change my initial plan. So, in turn have a few more questions that...

    New TPMS Sensor Reset Help Needed

    Well, with the holidays, work, and school, I have had limited to get back to this. So, after pulling all of the outdoor Christmas decorations down today, I decided to take a minute to do the relearn procedure. Long story short, it did not help. At first, it gave me an error, and lost all 4...

    New TPMS Sensor Reset Help Needed

    Thanks for the tips. After leaving Discount Tire, the truck is aware of all 4 new sensors, and they are all in the right spots. However, even with that all done and the correct pressure in each tire, the low pressure light is still on. My question was whether the manual relearn (as shown in this...

    New TPMS Sensor Reset Help Needed

    I had a bad TPMS sensor on my right front tire, and when checking the DIC I would only see "--" for the tire pressure. Since one went bad, I felt the other 3 could go at any time, which would be my luck if I only replaced the bad one. So I bought a set of 4 new TPMS sensors off of eBay. These...
