What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

[Jeff_]

Took the time to change my trans fluid. Super easy to do with some tubing down the fill tube and a cheap harbor freight hand pump. I have a 1000+ mi trip this weekend and I just hit 45k miles. When I get back from the trip I'll drop the pan and change the filter and do a few flushes to get all new fluid in. BUT for now, this will at least do something.

I use to like 24/7 loud exhaust but not anymore. At least 99.9% of time, but for that .01% i got this little 3.5" guy, just to make babies cry

JLT 3.0 catch can. JLT catch cans are so nice i even installed same one in wife's 2020 Altima AWD with small madification

I think I need to do this. Did you notice much of a difference in sound?

It makes it a tiny bit louder, also makes it sound like a lawnmower in V4 mode if you have not disabled it already

 

[Slow5.0]

Whats v4 mode
Jk. It was 1st thing i disable when i got Hptuner, same night lol
Its little louder on start up and driving up to 50% throttle. But at WOT its same since it would open by its self at WOTAlso if you have CAI, you wont hear exhaust, just fresh air goodness lol. Lont time ago i sad no more modding cars, but here im doing same thing i did to my old 94 5.0 Stang, just this car or suv was $80k, Stang was $5500 all stock when i bought it back in 2002 lol

Hahahahhah said the same thing a very long time ago. That's not gonna happen. It's a addiction.

 

[Slow5.0]

I had heavily moded 94 Stang, got married, sold my baby so wife can give me 2 new babies. I kinda never quit modifying stuff, my daily driver KW 18 wheeler keept me busy, did a lot mods to that sucker lol
Tell my wife about addiction, she said if is not cars, than its knifes or guns, or RC cars, or semi truck, whats next lol

Definitely noticeable on start up and idle, a like Wes and slow5.0 said, a little more growl up to a certain point. I was actually pretty surprised at the difference on my Escalade, subtle but noticeable.

If you have picky neighbors they may start to hate you. I know its not cat back loud but its louder with valve open on cold start

I have a 950hp Camaro that they already dislike. I could throw open headers on the Tahoe and they’d still be happier with me lol
But good information nonetheless!

Been a while trying to get back in the mod groove but keeping busy with work and several other fronts. Picked up a full set of apliques that install along the side windows. It all started when one of the apliques came loose.

The nut is bonded on and the small clips are basically one time use. I am sure there is a way to repair (better adhesive product) but I don't have the time nor the patience. Picked up new ones, color matched and installed them.

Drove 600 miles through the Arizona desert (122°) towing a trailer full of furniture and other things. I kept an eye on the transmission fluid temp the whole time. Mostly hovered around 187°-192° but going up some steep hills or sitting in traffic in Phoenix it would climb up to 205°-210° and once I started moving again it would cool back down to ~190°. Once I’m back home I think I’m going to remove the thermostat on the transmission because I think that’ll help it run cooler from what I’ve read on here and other forums.

What exactly is the flapper mod?

 

[STORMIN08]

he is referring to keeping OPEN the exhaust flapper valve, this is a pressure controlled flapper that moves under exhaust pressure, helps kill drone on a NON DOD vehicle...

if you have not disabled the DOD you may not wan to perform this mod, it will sound odd when DOD kicks down to 4 cyl

I have not. But If I tune the truck I might do the dod delete with it

 

[Slow5.0]

Tune will only disable it, real dod delete kit will cost you $1500+ in parts, than its deleted for good

Installed auxiliary light pods to help with backing up at night! 5% window tint isn't very friendly at night.

Too much chrome, so red line emblems
