CRV Transmission whine when accelerating

[mightymousetech]

Apparently it's very critical that the diff fluid is changed on time and routinely even though you know that 75% or more of owners don't do it. Pretty sure it was @mightymousetech that said it is pretty much mandatory.

Yes. As the clutches wear, the contaminated fluid will not allow the clutches to slip properly. But normally that only results in chatter/binding from the rear diff when taking sharp turns. Does not usually make any noise when driving straight when the rear diff is basically doing nothing. I would be more likely to start by replacing the transmission cooler line filter if it has one.
