Unless that warning is incorrect and that braking system can handle some missed maintenance intervals.

With the wet brakes, the need to change the transmission fluid is based more on mileage than time. The metallic fragments from using the wet brakes gets suspended in the fluid and decreases its effectiveness over time as the fragments accumulate. I recently changed the transmission fluid in both our Yamahas after two years. The fluid in the cart with drum brakes was totally clean and didn’t need changing at all. The fluid in the cart with wet brakes (which takes over twice the volume of fluid and requires friction modified fluid) was noticeably cloudy and ready to be replaced. Going forward, I’ll change the fluid on the wet brake cart every two years just to be safe. The other cart can easily go several years between changes.
