CVT problem: Valve body or Torque converter?

so, I have searched this forum and I'm kind of confused. I'll describe my problem:

when start moving from stop, there is a big "hick up" - the car refuses to move and almost choking, then jumps, and then start to move.

it happens all the time, unless i warm up the gear with "kick downs" while driving before stoping (actually it started happening when the weather got realy cold) . the problem does not exist when i shift manually in M mode.

also, when i'm around 20 mph, crusing at low rpm at D, if i want to accelerate- i feel a little vibration.

this two symphtoms are new. its a 2011 2.5 with CVT, has 120K miles on it. No warning lights are flashing.

from reading here, i picked two possibilities:
- Valve body (solenoids) failure
- Torque converter

which one of these are connected to my problem, if at all? could it be just an oil change or re-programing?
Thanks guys!

we dont have the exttended warranty here

Actually... It's NOT past the extended transmission warranty. That covered for 10/100K or 1 year from the letter, whichever was longer. The letter came in July/Aug. so the OP should still be able to get repairs under that warranty.
It's only an offer of Subaru US and Canada. which is totaly wrong. Subaru had to force all states to do so (I live in Israel).

I will go for a CVT fluid change (can I do that by myself?) before I'll put more money into it. And I dont think it's the fuel pump, as in M mode the angine works fine.

update

Check your fuel pressure. I had to replace our fuel pump at 50k with symptoms like your describing. What is your current mpg? On the vibrations, check your drive line mounts(trans, motor, center). I replaced all of those mounts and cured our car of all it's vibrations and clunks. I agree with the other poster, a CVT fluid change is probably in order at 120k.

Today the car started to make small "jumps" while driving at 40 mph with a steady foot on the pedal. It certainly looks more and more like a fuel pressure thing. also, I noticed that when starting from stop with "heavy" foot on the pedal, the car would go with no problem. but with "light" foot- It will make a big "hick-up". So it's also indicating that with anough fuel pressure- no problem.

only thing that puzzles me: why on M mode and light foot it will go fine? if I have to guess: on M mode the CVT is less sensitive for lack of fuel pressure...

OK, final results:
1. after few weeks, driving with the problem as described at the first post of this thread, finaly the "check engine" light flashes, and temp oil red light flashes too.
the code check:
"solenoid malfunction" (P2762) at the cvt. that cured the problem for 900 US$ including 250$ oil fluid. driving few weeks now, no problems, gear is even more responsive now.
so:
1. staling after stoping = tourqe convertor
2. hassitation and kick when start moving = solenoid

One problem: Subaru dos'nt yet offer the extended warenty in Israel!
thinking for forcing them to, legaly.

How can i prove that i have the same CVT trans as at the US? is there a "Gear Guide" somewhere?
It's a 2.5 liter 2011.
Thanks!
