Shifting gears jerky, cruise control out

Light goes off if driven super carefully, not rushing.
This has been going on for a month. We had pressure sensor issue, fixed. Then oil change where a experienced recommended mechanic added our transmission additive with the oil (instead of oil additive) instead of putting it with transmission fluid. He just told us *I added that bottle (one of 2 he was given, but wrong one!) To the oil." As if he had done nothing wrong. He handed us back the oil additive.

So, we know we need completely fresh oil (blend) and work done.

The car seems fine and can drive fine but when it takes corners when accelerating, it is more sensitive. Going up hills, it often requires one to take all pressure off gas pedal until it drops a gear down. Then it gets right gear or whatever.. Then acceleration slowly is fine a little.

Like at top of each gear range it gets. Shaky, sometimes it drops in; sometimes we must let it stay in lower gear until it accepts it.

If this is some protection mode! It is ineffective since everything still basically works except cruise control.

The engine light has stayed off for days if we simply go under speed limit generally, super gentle acceleration, and watch the rpm's.

? Could it be a pressure sensor? Hopefully husband will be able to answer your next questions. He's worked and now asleep.

Thank you for your time and consideration.

I appreciate your information, time, and kindness.
I read it may be going into.

. Idle when I thought it was gear issue. It was another chat user that also had Pt Cruiser. May be vacuum.

We are in AL and currently have only one car. We will get the codes ASAP.

At least the car is doing okay otherwise and goes over 50 miles daily.

Thank you

Code P0334 and P0335.
Cam shaft position and crankshaft position sensors.
The clerk said 335 meant mechanical but the papers don't say it.

Perhaps timing belt issue caused this.

It has gotten worse. The engines simply shuts off for no apparent reason while moving or upon attempting movement. So far, it's only been while 15 mph or less. But at those times no shaking or changing gear sounds, just off.

It cranks after but has quit immediately after putting in D. We waited a couple of minutes, and it was okay.

We did take it to the Chrysler place in our town but they said they don't even have the diagnostic equipment for 2005's. Really. I'm near Gadsden, Alabama.

We don't mind investing in our car. Even though my ex had her for 2 years, I bought her before him! I drove her off the lot in 2005! Yep. I'd like to take care of her.

Thanks.
