Add me to the troubled condenser list...   About a month ago I was driving to work on a sticky Houston night, about ~75*f or so with probably 80% humidity when I noticed that my A/C was not blowin

Hopefully your ac is working great now?     I don't think I'd join one of these class suits over $1k. GM will settle for a fraction of the class costs and most of that will go to the slimey lawyer

Add me, 2016 Serria Denali 60k no ac, but I moved from Maryland to South Carolina and didnt have the time to get it fixed and we made a few trips now have 67k. I bought used at 53k, had the trans flus

Has anyone had to add tranny fluid after the condenser change? 

I added a little just because I knew I lost some. According to the dipstick I didn't need to add any?.

Yea I figured. I changed my condenser after a tranny drain/fill. Fast forward a few months my tranny has a hard shift from 2nd-3rd. It has been doing it for a couple weeks so I finally checked the fluid level and it’s low low. Like don’t drive low but I have no signs of a leak anywhere. I have an appointment at the dealership tomorrow and have a feeling that they going to say it my fault. I think they didn’t add enough fluid.

I’m confused, why would you loose tranny fluid when changing the condenser?  And about the dipstick; where the heck is it?  I can’t find it and am under the impression there isn’t one and the tranny is factory sealed.  Lastly, how did you add fluid and where?  Eager to learn...

The condenser is also a transmission cooler.  It has two flow circuits in the same component so you’re going to lose a small amount of ATF when you remove the condenser.

 

As to the dipstick, my understanding is that the 6 speed has a dipstick in the K2 trucks, but the 8 speed does not.  On the 8 speed, there is a stand pipe on the plug in the pan and you fill through that pipe, but only after the fluid is up to temp and with the engine running on a level surface.

Because the condenser works for the a/c system and is also a transmission cooler.

The transmission cooler lines are located on top of the condenser on both driver/passenger side. They are held in by clips.

If you take the condenser out carefully, you can transfer the existing condenser transmission fluid over to the new unit which is what I did.

Don’t they do that when they vacuum and recharge your AC system?

I replaced the condenser myself for around $200 all in.

Didn't want to pay a shop $700-$1200

Pulling a vacuum only involves Freon, not transmission fluid

The A/C and Transmission lines are separate.

I had a shop installing the condenser including vacuuming and recharging my AC system as it leaked it all out 80$, the part was like 170$ But didn’t have to come out of pocket for any of it. If I would of had to paid still seem like a reasonable price. 700$-1200$ I would of probably kept looking for a different shop

That's right. The ac and transmission lines are separate, but the transmission cooler is in the condenser so it is good to add 1/4qt of fluid just to top off the condenser.

I added fluid to the new condenser from the old condenser, as my transmission fluid had just been changed a few months earlier.

I saw no need to go buy a quart just to use some of it when there was already fluid from the factory condenser that would work fine.

I have a 2015 LTZ Z71 with 41,100 miles and seems like I am leaking refrigerant from the condenser. Really sad that this truck is having these kinda issues and of course, no help from the dealership. Warranty expired May of 201920190827_181648.thumb.jpg.05d2435b81b21ff5d766bb8cf9fd7665.jpg

Oh I went aftermarket just cuz I got it for really really good deal “free” lol my mother law works at auto parts place so I didn’t have to come out of pocket, I think the OEM just has a piece of havc tape on the corner area where it tends to leak at kinda like a heat shield.

      I also found this.. API activated emergency provisional licensing because of base oil supply conditions meeting force majeure thresholds.   I wonder what's being substituted for Group III base oils...

      Oil Consumption

      By chris21 · Posted

      You seem to be struggling with reading comprehension.   I HAVE SAID 3 TIMES THAT THE BOTTOM OF THE CROSSHATCH IS A QUART BELOW FULL.    I have also said that the manual will not call that "1 quart low" because it is not a quart below the acceptable range in answer to asilverblazer saying that he has never seen the bottom of the marking noted as "1 quart low" in a manual. The wording of the manual allowing for an acceptable range would indicate that .00001" above the add mark is ok. Also, because the manual allows a range, a quart below full and a quart below acceptable are two different volumes. Thus the manual will not use the phrasing "1 quart low"

      injector cleaner 2021 2.7 1500 silverado

      By Grumpy Bear · Posted

      GDI Injector tips are in the combustion chamber and yes, they are subject to the same aromatic hydrocarbon based carbon build up the entire chamber is subjected to. Chevron Techron is a PEA based cleaner (polyether amine)  that is VERY effective if the dose is high enough.  Carbon the tips disrupts the spray pattern so keeping them clean is kind of a big deal. It will clean more than the injector tips. It will keep the inside of the injector tip clean as well. When they shut off they 'hot soak' building varnish internally behind the pintle. The tip, unlike most MFI systems have several orifices of very small diameter. They have to stay clean to work right. That spray pattern is supposed to spray into the cup in the piston, not all over the cylinder walls. Old guys will understand...    Top Tier Chevron has enough of the cleaner to be effective if used regularly. Other solutions could be Shell V Power Nitro + Premium and Exxon/Mobil Supreme Plus Premium ONLY use a different chemistry to the same effect with the added bonus of a friction/antiwear additive as well. Red Line SI-1 is PEA based as well with an upper cylinder lube. There's a white paper on their site for shock treatment of system left untreated for long periods. AMSOIL PI has a full system cleaner of yet another chemistry that will strip carbon out of the power cylinder pretty quick. Gumout Regane is also PEA based but at very low doses and those that are isopropanol based will not be effective. Alcohol content is way to low. Chevron Techron in any pump gas, Use by package instructions. 10 oz per 15 gallons every 3,000 miles. First use may require two treatments.    So, Techron, Red Line SI-1 and AMSOIL PI if batch treating and Shell, XOM Premium or any Chevron Fuel will not just keep it clean, but will clean it if dirty. No other fuel "I'm aware of will do that".    Flex Fuel motors. If you use at least 40% alcohol on a regular basis they won't carbon at all. PEA is not recommended for fuels over E-20     (www.carparts.com)

      4 Wheel Drive System

      By Another JR · Posted

      It is always a good idea to exercise it at least every few months to make sure the actuators don’t get stuck. It is also a good idea to actually drive it for at least a few hundred feet when you do that so seals experience motion and oil movement.  Off pavement or snow/ice is best for this, but driving wet pavement in a straight line for a  short distance will work if you don’t have other options. I have  forgotten and gone as long as six months between exercising it on my 2021 and it has always shifted promptly.  I usually just use my straight 300 foot gravel driveway.
