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

[Sam Harris]

Thanks Mark! Baby Girl! It's number 6 for us (hence the huge vehicle with lots of seats). We'll be balanced: 3 boys and 3 girls.

Wow! Congratulations to you and your wife! Awesome!

Like the Brady Bunch lol! Congrats.

Exactly!!

Wow. That’s how many kids my parents had. I don’t know how my mom did it. But it’s way less than my dad’s parents had-12. Now that must have been crazy.

Holy cow! Were they a farming family?

Amazon is Toying with me now, sending me one rotor. My goodridge lines are back order till the 29th

Weak..! Wth. One rotor?!? And the back order too..? Dammit!

This is annoying me View attachment 276189

Sonsofbitches! Dammit T..!

So, sometime in the near future, I’ll be converting to efans on my 2003 Yukon (yahoo!!)..

I know this has been discussed at length on a number of threads, but so far, all I seem to be able to find with the real details are very old threads, and all seem to be using either the BBP harness, which does not appear to be available any longer, or the ones from Nelson, which like to melt and fail.

Can someone point me to a thread, or write it up, for using a OEM harness, OEM fuse box, containing the provisions for the efans, and OEM fans..?

Here’s ScottyBoy’s write up. He seems to have disappeared, I couldn’t tag him. I hope he’s ok. I bought my OEM harness from him. And since yours is an 03, don’t pay any attention to adding the aftermarket relay he talks about. I had to add that but you don’t. All you need is an OEM harness with the mini fuse box/ OEM relay setup.

my dumb evap code keeps popping up. decided im not spending another dime on the evap, deleted all evap codes today. no more cel. done.

also tried to kill the traction control in the tune, ive likely got a bad ebcm. made a few changes it no longer makes the buzz sound when the tc kicks in, but it still kills the throttle. im going to play with it some more tomorrow and make a few more little changes.

I also tried tagging ScottyBoy and it wouldn't do it--weird. He hasn't been on since Feb 2020. I really hope he's ok--seriously. I remember him saying he had some health issues. Damn....

Thanks Mark.

Yeah, I know. I was trying to reach him a while back. I hope all is well. [emoji1317][emoji45]

So do I Sam. That goes back to what I was talking about a few months back--members who are here all the time shooting the $hit, or helping fellow members--and then just straight up disappear, without warning. Sure there's members who sell their rides, or just take a break, but what about the guys who just go ghost. Those are the guys I wonder and worry about.

For sure. It’s weird and a little disturbing. It seems like we’re close but only via interwebz, so don’t have any other contact, or knowledge/ means to reach anyone. I was just messaging another member, saying we should do some kind of local meet. That would be so cool. Hell, it would be even cooler to have some annual TYF national meet!

That would be cool. I hate that I like alot of you guys

Me too *******.

I know I am newer here, but I have always enjoyed the closeness that you get on a forum that you just don't seem to get on other platforms. there are several forums that I was part of and most just have mods/owners that just fall away and everything gets shut down. there is a few of us from some pages that have stayed in touch, but so many that have not.

Long story short I have a 2003 Tahoe being delivered tomorrow for a buddy that needs a cheap beater when he gets back from Cuba. All I know is that it has around 230k, is 2wd, has the exhaust cut off behind the cats, and the tranny leaks so bad that it's gonna show up dry. So the first order of business is pressure wash and fix tranny leak, the PO says it leaks from the tail shaft seal but I know nothing about 4l60s. Is the tail seal a common spot to leak? Or should I plan to drop the pan, change the filter, and maybe throw in a corvette servo?

The goal is just to get it daily driveable for a few months then he will flip it later on this year. He paid $1500 for it, this is the only pic I have.

Also was told it's a fully loaded LTZ but we all know LTZ wasn't a thing for NBS, maybe he will get lucky and it has captain chairs and the other good interior bits.

Could be the rear output shaft seal (GM 24232325) leaking. Mine failed when I pulled the driveshaft after 15 years and 200k+ miles (the seal was old and brittle and finally gave out due to the trauma). It was easy enough to fix - took about 30 minutes total. However, I would plan on a filter change while you're at it since you can get the filter and gasket for about $30.

As for the corvette servo, I'm afraid I have no experience there so I can't make a recommendation. I've been lucky - my transmission is still all original.

I did not realize the filter and seal were so cheap. As soon as I can rule out a cracked case or something crazy I'll get those ordered. Thanks for the info!

definitely do the Vette servo. Easy $20 mod.

If it leaks that bad it could be on its way out...

 

[TheAutumnWind]

So I've resealed the hydroboost twice now. Still leaks. Any tips or tricks? Maybe I'm just buying the wrong seal kit?

It's very possible the tranny is on its last leg but anything to keep it holding on a little while longer will be the goal. I'll have to research the corvette servo more, I did a quick google search and found kits with multiple parts around $60-$80. I have no idea what I'm looking at tho so I guess I need to go to the stickies page.

Fixing the leak and keeping it full of fluid will make it last longer, I don't see the point of installing a corvette servo on something you plan to get rid of, nor do I see how it will make a transmission hold a little bit longer. Now if you plan to keep it and want to reduce wear that's different.

 

[NoReverseYukon]

I kept getting the ABS and BRAKE warnings which never seemed to throw a code and would disappear the next time I turned the key.
Decided to clean up the grounds and see if that does anything. While under there, I noticed how rusty the frame is and how bad the brake and power steering lines are.

I see in my future the next things on my to-do list

 

[treehan77]

20 bucks says your ABS module has bad solder joints. Easy cheap fix. Need a soldering iron, solder and flux, and some RTV to reseal it after cutting the case open.

edit: hopefully all that rust doesn’t make it a PITA to get the screws out for the module, they’re already tricky
