After researching differential n the net I found out that differential and transmission share the oil..
So I should just change transmission fluid right?
Also I found following link
http://www.pelicanparts.com/catalog/shopcart/986M/POR_986M_SUSaxl_pg1.htm
They sell differential oil.. but they mention front and rear differential... it's confusing.. should I buy 3lt of this oil from pelicanparts and change my transmission fluid? will this solve "low differential oil problem"?
Thanks
