Chevy has now added an entry to the Oil and Fluid Life display under the maintenance tab for the DCT’s canister filter which shows the amount of life remaining.

The 2023 Corvette Owner’s Manual recommended that owners replace the filter at 7,500 miles and then again when the odometer turns 22,500 miles. However, if the percentage of life is less than 10%, the manual recommends changing the DCT canister filter immediately as performance issues may result.

Here is what the Owner’s Manual states:

Transmission Filter Life: Displays an estimate of the filter’s remaining useful life.
If REMAINING FILTER LIFE 99% is displayed, that means 99% of the current filter life remains.

When the remaining filter life is low, the REPLACE TRANSMISSION FILTER SOON message will appear on the display.
The external canister filter should be replaced as soon as possible.
See Dual Clutch Transmission Fluid Life System (page 249).
In addition to the Transmission Filter Life system monitoring the filter life, additional maintenance is recommended in the Maintenance Schedule.
See Maintenance Schedule (page 306).

Unknown at this time is will GM do a software update going back to past C8 years to also have this DCT filter monitor
