Transmission issue?

[Twistoffate0817]

Hello all, I have owned my 2009 yaris for a year now, and have become very frustrated with how this car drives. I need to hear your opinions on if this is how the vehicle is, or does it sound like something is wrong, causing the vehicle to drive in this manner.

Okay, so I have had two incidents where the engine would not start. This is when i was using shell gasoline. So i switched to Sunoco. The problem fixed itself so far.

Next, Whenever I go from 20-40 mph, the car feels like there is a thousand bricks in it. It feel like its heavy and drags. I have to push the pedal down hard, and even then it still wont go much faster. Once im over 40 mph, it does a bit better.

Once i take my foot off the acceleration pedal, and the speed gets down to 25-20 mph, it jerks out of gear. It is the strangest thing, and it ALWAYS does this. I have had this jerking sensation when i hit 30 mph too.

The car sometimes shifts in weird intervals. A few days it will shift at 30 and 40...then sometime 35 and 45. It is always all over the place when shifting.

I have taken the car to the toyota dealer twice, and they have found nothing wrong with it,and have claimed they cannot feel the jerking and shifting sensation.

I am at a loss because the problems with this vehicle have caused me to start looking for a different car. It only has 8000 miles on it, and i love this car, just not the issues it came with.

What should I do?

Is it because i use synethic oil?

Also, In the mornings, when i turn the stereo on, you can barely see the numbers and what not. Very dull lettering.
Thanks.
