Is adding 2 Litres of transmission fluid a must?

[rtrombley3]

What's the consensus of adding the extra 2 litres of transmission fluid? I can definitively say that I will never track my car and I've seen articles where people recommend adding the extra fluid even if you have no plans on tracking the vehicle. I've read it should be done anyway to help with any possible transmission problems. Just wondering what people here have done?

If there were ANY concerns about not enough fluid, GM would have added it. Don't listen to backyard mechanics that like to hear themselves talk. The designers of the transmission are far more knowledgeable than them. The extra fluid is recommended for heavy track usage that the car is capable of.

Agreed with above. For regular and spirited driving, you’re Good as is.
if tracking car then it is a recommended must.

Hey ..... Yes that was a big concern of mine too.....I wanted to add it just for piece of mind.

But the service advisor at Humberview ( where I got my C8 ) and one of their head Corvette mechanics swore up and down that for " spirited " street driving it was not required.

I wont track my car either ... Im worried that if I scrape the rubber off my beloved C8 with a straight razor I may damage the paint

Do I trust the dealership ? Not really but yes GM engineers say the same thing.

Its all about the massive heat that is generated on the track that is sustained for such long periods.

Heat that wont be generated on the street. Sure I drive my vette at times the way it was intended,
but not constantly I really dont abuse it at all....otherwise things will inevitably break.

In my case and probably alot of other C8 owners If something messes up with the DCT I doubt it will be because of the absence of the 2 quarts of tranny fluid.

Best option i ordered on the C8 is the extended warrenty.

Happy Vetting all !

I forget where I saw it (or read it) but GM did also mention somewhere that sustained high cornering loads on the track was also one of the reasons for the extra DCT fluid, to insure no starvation issues. Not an issue for street driving, even with a heavy foot.

Yes, rather than heat, I read that the extra 2L was to negate any starvation associated with high cornering load.

I did the extra 2L and I felt like the shifts were smoother, less harsh. But it could be a placebo effect...

If it is necessary for the track, then it must be good/better for anything less, such as the street. Old adage comes to mind…“more lubricant” more smiles per hour.

I hear the factory started adding the 2 extra quarts in the past year

 

[Jack Raccoon!]

I guess GM didn't tell the rest of us because they don't want to assume liability...

 

[PapaSmurf]

I put 36,000km trouble free on my first C8 without adding the extra and I drive like a d@#k!

A US dealership technician stated they've been instructed to add two quarts of fluid to all corvettes before delivery.

It can't hurt, but throwing good money after bad doesn't help either.

I added the 2 litres, doesnt seem to make a difference in the way the car handles.

It should soften the return rate of the springs. Kinda like Mag Ride without the price tag...
