Default Pic: filling DCT with 2 extra quarts

From my dealer today. Not my car, though mine is behind it in line for the service.



Looks like you remove the panel to get to the air filter, then remove the air filter housing. Not the end of the world.

From the service bulletin on this procedure, there were a few bolts that if you removed, would bork the whole trans. Thankfully none of them appear readily visible and lurking there

My dealer will also be flushing out the OE brake fluid with a track-worthy equivalent, will share if anything unusual comes of the process.

Nice... I saw Alan post those today on FB. Those other bolts you see are the shift shaft supports and will FUBAR the trans. The fill plug is a different color and has a femal hex insert vs. a bolt head; you can see it sitting on the tub there facing up. Let us know how the brake flush goes. What fluid are you going with?

Normally I use Motul RBF600 but at Matick they have one of the AP Racing fluids in stock, so going with that.

Sorry to ask, but why is this process necessary?

This process is the transmission top off for track use.
I would assume that it has to do with better high g lubrication and cooling.

Why are you installing a racing brake fluid now? GM says the car needs to have 1500 miles on it before taking it to a track. That could take a few weeks. I usually change my brake fluid before a track event if it is over 4 weeks old.

Mostly logistics. The dealer who has it has track-savvy techs, and if there end up being any complications in bleeding the fluid on the new platform, they will be best equipped to sort through it. I plan to have the car on track within a week and a half of delivery to me, so there won’t have been a lot of time for the fluid to have gone bad, especially in dry and warm San Diego.

So the C8 manual does say 1500 miles before track use? I wonder why it’s so many miles .

The rings are seated and ring and pinion worn in well before 1500. Cam wear pattern established, etc...

It’s almost like a wide window for any manufacturing defect to emerge rather than actual break in.

I think it is mostly transmission related more so than motor related... or at least that's what I'm inferring from everything I've seen.

Most likely trans and integrated diff.

One of which already blew up on LGs car last night on a 100 shot. Stock tires.

Someone posted they thought axle broke... but that is usually collateral damage and a misdiagnosis in any independent rear suspension car when that happens.

There’s literally a picture of the broken half shaft.
