I had this pop up on my car’s maintenance minder display recently. I had never heard of it before. Some time ago I had a message pop up for changing transmission fluid but when I talked to two mechanics about it, one said they don’t do it and the other said you should never do it on my make and model. Is rear differential fluid similarly assessed? I feel nervous just disregarding what my car asks me to do haha.

    Ya… don’t disregard it. The manufacturer makes service recommendations based on what they think the car needs to continue to work. Your two mechanics are making recommendations based either on what they know how to do or what they feel like doing(or not doing).

    I’ve changed the rear differential fluid in our 2019 CRV. It’s just a little more difficult than an oil change, in that you need to actively pump the new fluid in the fill hole and there’s no dipstick to check it(you just fill until it starts running out the fill hole). Honda calls for their own fluid, so your mechanics may be disinterested in doing the job.

    Regarding the transmission fluid change, get that done too, moreso if its a CVT. Your mechanics may also be trying to avoid the transmission fluid change because Honda wants their own fluid for that, as well.

    I was a little surprised when our 2019 wanted new rear diff fluid considerably before new CVT fluid, but I guess the computers know what they are doing.

    Get a different mechanic. He’s giving you advice based on information from 2005. The other comment has all the other info you need
