Abnormal sound on Honda CRV

My 07 Honda CRV with auto transmission runs well, but when I shift from “D” to “R”, there is an abnormal loud sound like “ping”. There is no such noise when I shift from R to D. Any problem with the transmission? Thanks!

Way back when my '85 Accord started doing this. A change to Honda recommended (Kendall) ATF helped.

Get your trans fluid changed. Make sure they use what ever Honda fluid is called for.
Hopefully that will help you too.
