Honda crv rear noise

Hello JLO
I have a 06 CRV that started to have what I called a shudder from the rear end when making slow left or right turns just a bit over one year after I bought it new. it only had 14000 miles on it. I called up our honda dealer & they knew right away what it was. I took it in and they did a complete job called burnishing the clutches & in this proceedure the oil is changed 3 times. They said the factory had put in the wrong oil, so the new oil is DPF II In the manual it only called for oil to be changed every 90,000 miles, but I beleive they now say about every 30 to 4o,ooo. The old oil was a pink color ,this new stuff is clear. I have the complete procedure saved on my computer but don,t know how to attach it to this comment. Oh yes and this was all done under warranty, no cost to me. I will change the oil myself the next time it is due for change.
