Have a 1985'ish 2165 that makes a slight ratchet sound, from right rear. The sound is made only in right turns. Was planning on changing transmission filter & oil, but wanted to see if this sound may be indicator of something going south..

Let me know if anyone has idea on what sound is about and/or recommended options to determine if there is an issue

Looking to use Amsoil 20/50 Hy-Tran oil or another quality product if have suggestion.

Thanks
