Default DCT Changes / Updates

My 2020 Stingray was built in September 2000. The DCT was replaced in September 2023. The new part number is 24047269. I see that it replaces 24045885 & 24047778.

Is there any way that I can find what the differences are between these transmissions? I'd like to know this for future recalls or service.

Don't hold your breath waiting for them to get back with you. Hope you have better luck if you call again.

The correct number to call is 800-222-1020 but it may transfer you somewhere else depending on what the computer wants to do. Make sure that you are really in customer service.

I have my answer or at least a reasonable one. The replaced transmission only fits 2020 Corvettes. I have to assume that it has only minor differences from the superceded parts. I had expected that thr replaced transmission might have been updated to correct known problems. Evidently that must not be so. This probably minimizes any furthur service concerns.

My warranty is not extended and I have to pay for the initial 7500 mile transmission filter replacement.

Sounds right. And based on recent comments during the bash, to once again confirm the mileage for the second filter change - it is at 22,500 miles and then every 22,500 miles after. I have attached the statement from the bash. So the second change is intended to be 15000 miles from the first one. This is consistent with answers the same folks have given in the past."Corvette Today – 212 - from the recent bash:

"Question by Andybump about how the DCT Filter Life Monitor Works, is the second change at 22,500 miles, or is it 22,500 after the first change?:

Josh Holder: So, the second change is at 22,500 miles, then 22,500 miles after that."

That is for those with their original transmission. All of my service is moved forward 7500 miles.

That was intended to be my point. You need to have it replaced 7500 miles from whatever you had when its replaced (which you said), and then15000 after that and then 22,500 miles after that.

It was just meant as a reminder that the second change interval is also shorter for a new transmission.
