I recently tried some new lines at Barber and started overheating the A6 transmission in my 2014 Z51. Was wondering if anyone had tried these (see below) and have they helped? Help, I want to get through this HPDE season and get the ZR1 next year!

CORVETTE Z06 QUARTER PANEL VENTS

Substantial airflow is critical for maintaining cooling performance on the track. The Z06 Quarter Panel Vents for Z51 models offer larger openings for increased airflow to the transmission oil cooler and differential cooler – an approximately 25% improvement over the airflow of the Z51 at track speeds (based on CFD analysis).

I have a 2015 z51 (which I have heard had even worse overheating issues so this may not be relevant)
I replaced my quarter panel vents with the Z06 scooped ones and it jack.
I then tried wrapping the exhaust in titanium exhaust wrap.... Still Jack.
Even at my list track day which was a brisk 60 degrees (Hey, its Texas, that's parka weather) it was still over heating.
Maybe someone else has a different experience but as far as I can tell... It's gonna take a secondary cooler to keep up with me!

The Z06 has the air scoops on the fender vints they all so have a larger oil cooler with fan on a6 & 15 a8 & still they will over heat.

I noticed about an average of 10 degrees cooler after installing the Z06 scoops over multiple track days, I tried to account for the variance in outside temperature.

Though I have a manual so I'm sure it has little bearing on what you're asking. Just thought I would share.

From talking to people running the same z51 2015 at the same track and same day i was at (i.e. same conditions) the auto A8 had the problem of overheating, the manuals didnt know what i was talking about.

Unfortunately, at my height, in order to push in the clutch i have to sit unsafely close to the steering wheel so im stuck with the over heating auto.

You should also use a bigger transmission oil cooler core : )

I have to say, though, despite the much larger core, the overheating is still a potential issue. My temps keep creeping up about 30 mins into the session.

I am looking at the LG Motorsports transmission cooler and larger pan... and waiting on the ZR!!

Just keep in mind, Z06 cooler core is just as big, and is only $200. They both require a bit of trimming to make it fit.

One of the forum members had a shop splice into the lines, and install the OEM Z51 cooler as well in addition to the Z06 cooler core, which seemed to be very effective for the owner. Not a bad idea for severe duty...

I will say something someone suggested one track day has helped tremendously

its a stupid simple solution

go buy a cheap (big) fan from walmart, jack up the back end of the car and stick it underneath. I got one of those that rotates on a stand so that it cant be parallel with the floor

has ALMOST ELIMINATED the problem.

Also, I actually just received a reply from LG about their coolers (which on the website are listed only for the A6's) and here was the answer:

Currently for the A8 transmissions we only have the cooler setup for those cars. We are finishing up the pans and should have those out in the first part of 2017.

So for your car currently you have two options.
The larger cooler, this would replace the smaller cooler behind the driver side and would be stage I. This adds approx one more quart of cap to the system and increases cooling area.
Adding the second cooler along with the stock cooler. In the stage II setup you would replace the driver side with our cooler, and then move the OEM cooler to the passenger side with our supplied brackets and hose and now you will double the cooling area over stock and add approx 2 quarts to the system. For most track guys this has kept the cars out of limp mode.

not that that has a bearing on the OP but since its on topic i thought i might post anyway!

I installed the Z06 vents on my Z51 but mostly for aesthetic reasons as the ones painted body color became available. Once installed, I did notice better tranny temps here in the Florida Inferno.
