Hello thought maybe I could get some help from here. I bought a 2012 Volvo S60 T5 about a year ago as my first car. The car is great but I have experienced some weird jerking when I have either slowing down or stopped at a light. And sometimes it jerks hard when upshifting. I called my local dealership and they said that Volvo doesn't mess with the transmissions and they have "lifetime" fluid. I have 76000 miles on my Volvo. Should I change the fluid. I know that sometimes it would shift hard but now it is very noticeable and it feels as if the transmission is going to go out. Also I noticed that when I opened my engine hood, there isn't even a dip stick for the transmission fluid.
