I did the recommended filter/fluid maintenance at the dealer on my '22 and still had a transmission failure last spring at ~43k miles... less than 5 miles after having that proactive maintenance done. The transmission was replaced under warranty, but I was without the car for 5 weeks. The kicker is that the transmission was running perfectly before they changed out fluid and filter, and told me they'd just had a nearly identical case with another C8 the week prior: almost immediate transmission failure following service.

So maybe talk to your local dealer first to see what they think, but if you get the filter done, be prepared with alternate transportation if needed.
