Alright, so what standards do you propose we go off of?

Dexron is still a better standard than your anecdotal experience, especially on a fluid that not a lot of people heard about before.

You don't even have a manual Camaro that you can experiment the fluid on. How do you know it will work well in this specific application?

I noticed the viscosity difference as well. If indeed there is an "optimal" range of viscosity at which the transmission shifts smoothly (or as smooth as it is able) that might explain why when it's cold, the thinner fluids (ATFs) provide smoother shifting, but don't do as well as higher temps like that seen on the track.

It also would explain why M3Bs and MartinLE report the Tremec brand fluid being at least as notchy and clunky in the cold (greater viscosity than the ATFs and OEM) vs OEM, but better on the the Track.

I'm not a fan of the notchy/clunky/grinding when I first start driving in the cold, and would prefer a fluid that smooths that out. However, in my car it seems to improve greatly after the trans starts to warm up (5 mins or less of driving). So I guess if I could have a fluid that shifts well on the track and is no worse in the cold than OEM, that's what would be best for me.

Does Tremec fluid fit this description? It would be great to hear from some more users of the Tremec brand fluid.

It's simple, although many like to try to make it complicated to sell more x branded oil: buy the most cost effective synthetic available in the proper grade, that's it. How do you determine the "best"? Standardized wear tests combined with used oil analysis. All modern major brand synthetics will pass GM standards with flying colors, but some don't want to pay up for the certification/label. Castrol Edge (engine oil) is a perfect example - it's better than M1 (and cheaper) based on any standardized testing or UOA. I've followed oil threads for almost 25 years and there will always be brand/cert huggers so I know this is a waste of time, but that's the reality

It’s kinda scarce lately, but keep an eye on the website.

The Tremec fluid appears to be in stock here...

Here's the rub, though...

When an oil bears a certification label from a manufacturer, that is telling the consumer "if you use this product and there's a problem, the MANUFACTURER will stand behind you." So, when a mechanical item (motor, transmission, differential, etc.) breaks and you have been using a certified lubricant, it's GM that steps up and repairs it at their expense.

Where do they get the money to cover that repair? Yep... from the fees that the lubricant companies paid to get their product on the list of authorized products.

Will oils without the certification label pass the tests? Absolutely. But, what happens if you're using that oil and you have a breakdown? Who pays for the repair?

We live in a world where everything is a legal battle and you have to "prove it" before your problems are solved. So, the path of least resistance is to use the certified oil even though it costs more. And in the grand scheme, an extra $50-$100 per year for fluid changes with the certified oils compared to the cost of a $30k+ vehicle is considered "cheap insurance."

I plan to do it this way next time. I used the drain plug the first time and it's a huge mess.

I am not trying to be a smartass, but how can using a big oil catch pan result in a huge mess?
Center pan under drain plug - loosen drain plug - use fingers to remove drain plug and let fall into drain pan - allow to completely drain - reinsert drain plug - tighten drain plug. Done, no fuss no muss.

transmission support cross member right in the way it splatters on it go look at where the drain plug vs the temp sensor drain from

I have a 17 M6 and there is nothing within a country mile of my drain plug.

Well I can assure you that on my 2018 ZLE there is a large transmission crossover mount directly underneath the drain plug and it makes a huge mess. Not only that, but it pours into the top of the crossmember which is like an aluminum spider web full of wholes and spots for fluid to sit. It's a total mess.

This guy knows what I'm talking about...Big 'ol mess.

[MartinLe]

This is definitely weird! There is not a support member under my drain plug. It sits quite a ways back of the drain plug.

Could there be a subtle change between 2017 and 2018 with respect to the support member location?
