My 2018 Clarity has 60,000 mi. I just had the transmission fluid and brake fluid changed. For some reason when I'm in stop and go traffic the transmission seems to be clunking louder and louder than it did when it was new or at 40,000 mi. This started around 50,000 mi. When I pull into my garage and shut off the engine, I can hear it clunk slightly as well. When I'm in city driving and come to a stop light it doesn't clunk. I've owned 2 other PHEVs (Ford Fusion and Ford C-Max) and I've never had transmission noise issues. Has anyone else experienced this?
