Good day/night everyone.

So, my father has a 2011 Subaru Forester, 4 speed A/T, 2.5 litter, N/A. I believe the lowest trim one (I'm not a Subaru expert unfortunately).

The car has a little over 130k miles.

During the acceleration, the car shakes when it starts to reach 25 m/h and the shaking stops when it stabilises on that speed or goes past it. Also the car will shake during the whole acceleration period if you push the throttle fully.

Again, I'm not a subaru expert, but I think this issue has something to do with the transmission. Maybe it is slipping or something?

What I am asking here is that, is my suspicion true, or there could be something else a little bit easier to take care of?

Thank you all in advance.
