Hi, and welcome to genvibe!I change my oil about every 5ooo miles (8000 kms)You can download a copy of the owner's manual from one of the links in
http://forums.genvibe.com/zerothread?id=1010The owners manual says to use 5W30 oil. I do not know of any low temperature transmission fluid. There are people on here who are in cold areas, I do not remember anyone talking about a winter transmission fluid. There is no Pontiac Vibe plant in Europe. All Vibes are built in California, USA. However, most of the parts on your car are identical to parts used in Toyota Matrix, so if you are having trouble finding a Pontiac source for parts, you could try Toyota, if available. Most of the parts are the same, a few are different, and of course body styling, but if you are curious if a specific part is the same between Vibe and Matrix, just ask and someone here will find out and let you know.
