As of last week I started to notice very strange sounds coming out of the transmission. When you break and the car shifts down to the first gear, there’s a loud thud. At first I thought that the u joints are bad or need to be lubricated – unfortunately a solid greasing didn’t help at all. Anyone else get the thud when decelerating? This is very annoying and doesn’t sound good. I have over 50k miles on the car and it has been serviced at 15, 30 and 45k. Do you guys have any ideas what could be wrong with it?
