Grand sport 2019 Auto AFM

[Steve n Kate]

Interesting. I just googled this subject and an outfit called Keystone Chevrolet in the US say,
"Usually, differential fluid is changed after every 30k to 60k miles driven. This is a tough job, so must be handled by an expert technician. Only an experienced mechanic can properly wipe out the old fluid from your vehicle's drive-train."

My US import is at 8 years old and 30,000 miles so it might be something to consider at the next Ian Allan service in a year or so. I've recently done an intermediate oil change myself in view of low annual mileage.

C7 is a stunning car IMO. A great parting shot for front-engine Corvettes.

Hi Stingray,I have rejoined again after selling my c6 zo6 a few years ago so now I’m back in .
The diff oil replacement on YouTube looks like a really easy job,doesn’t look complicated at all.Are you meaning the auto transmission which looks a bit more complicated.
Doing a bit more driving today I’ve concluded that the v4 mode on my car only works when in Eco mode so happy days.
I was a bit disappointed that Ian Allen didn’t know about this as it’s a GM design feature for the UK market.
All the best
Steve
