From what I over heard, it seems the C7 Z06 in the garage next to us was overheating constantly. Was asking if anyone had the LG coolers on their LT4s.

There was a lot learned from the Z06 overheat issues. Kind of sounds like yours may have been trans but then I'm sure you had the gauges up to figure that out. Good way to finish the day testing the limits.

Yeah, I don't get why they recommend the 0W40 in the ZL1 and 15W50 in the 1LE.

As far as I know, they are the same engine.

They only require 15W50 for the track due to G-Forces this car and the ZR1 can produce.

It's 0W40 for all the Vettes and ZL1's on the street and track now so no oil change needed just for the track. I wouldn't change anything for AutoX but your run at COTA might be a good case for 15W50.

THIS!!! ^^^

RSFR, no wonder you're overheating and id say you're pretty lucky she didnt go boom, as W30 is insufficient viscosity for track duty for any V8 Camaro.

Here's a link for ya which should hopefully assist:

For what its worth - I was running 15w-50 and my PDR showed a peak oil temperature of 270 for most of the sessions. Again, this is driver dependent, but I was very happy with the oil temps on what ended being a very hot day.

What enhanced trans cooling hardware?

They added an additional trans cooler on the ZLE A10. They also changed the tuning and shift points on the ZLE A10 and differential is tuned different too.

RSFR,

You know my secondary cats have been eliminated & I've put blankets on the primary cats & DEI shielding on the A10 & eLSD cooling lines where they get near the primary cats. Also, DEI tape on the rest of the eLSD cooling lines, running all the way back to the eLSD. I was running Mobil 1, 15w-50w, data shows oil peaked @265F and trans peaked @230F.

If you can elaborate on WHERE the extra trans cooler is for the ZL1 1LE A10. There is not one, but, I will gladly admit I'm wrong if proven otherwise...

As per my question, I was asking about hardware changes not software.

The Radiator & the Aux Transmission Cooler work together to cool the Trans. The Trans cools the eLSD with a heat sink in the eLSD. This is why I took the secondary (unmonitored) cats out, added shielding to all of those lines.

The oil "cooler" is as much as a warmer as a cooler, a real oil cooler would not flow into the radiator IMO, it would be a stand alone. I've read that most people see a peak oil temp drop of about 30-40F degrees going external oil cooler.

I know all about the system. I am asking Sooner Cole about his statement that there is an additional trans cooler specifically for the auto trans ZL1 1LE:

"They added an additional trans cooler on the ZLE A10."

In this article, it mentions Chevy added a new transmission oil pan and an additional cooling duct for the steering gear while tuning the A10 for the 1LE. Everything else is the exact same as the ZL1 non 1LE A10.

...understand. That's not an additional trans cooler...

https://media.chevrolet.com/media/us...amaro-zl1.html

"This new transmission comes with many changes that live up to the requirements of the 1LE performance package. Unique calibrations were made to the transmission, electronic limited slip differential and performance traction management system. The front and rear Multimatic DSSV® (Dynamic Suspension Spool Valve) dampers have been tuned to accommodate the quicker shifts in weight transfer. New hardware includes a new transmission oil pan and an additional cooling duct for the steering gear."

[Vigilante375]

Exactly. I was backing up your statement.
