Air Bubbles in my S80 1999 Transmission
 

Hi,

I recently change the oil(Castrol Dex III)/Filter in my Volvo s80 1999 2.9L non turbo...transmission.

Oil level is perfect but when I check the oil while engine/transmission is hot...I can see the Air bubbles on the dip stick. I searched the whole Google but did not find a single good answer.......plus since I am in Middle east therefore our normal temperatures are around 50 to 55 C :)

by the way Tranny works 90% perfect...running smooth.

Any ideas from the gurus.
