I am changing the transmission oil on my 2010 4cyl. 5 speed today. I wanted Amsoil but, of course, I couldn't find it in Canada so I ordered it from the Amsoil web site. Ordered one day and here the next! It was $3.00 cheaper a US quart than in the parts store and the parts guys didn't have any and weren't sure they could get it even though it showed up on their computer. I see that they also have a 5W30 transmission oil which is specifically designed for manual synchromesh trannys. Has anyone tried it? Dave
