I would also check the wires going to the speed sensors on the transmission.

If everything checks out okay then its time to check for transmission codes at a transmission shop. Your range sensor switch inside the transmission might be the problem but you should be getting a trouble code for that.

Okay I'm going to try that! But would the speedometer jumping like that cause the jerking when trying to accelerate or?

The transmission range sensor tells the PCM the position of the transmission shifter. The PCM uses this information to control which gears of the transmission to enable or disable. When the transmission range sensor fails it can cause wrong gear starts, no up shifts, or what feels like a falling-out-of gear condition.

The cluster, PCM/TCM and output speed sensor all work together to calculate speed. The vehicle speed signal is taken from the output speed sensor. The PCM converts this signal into a pulse per mile signal and sends the vehicle speed message across the communication bus to the BCM. The BCM sends this signal to the instrument cluster to display vehicle speed to the driver. The transmission range sensor can effect how the PCM sends the signal to determine the speed.

I would suggest you take it to a transmission shop and have them check for codes. You need a professional qualified transmission mechanic to give you an accurate diagnosis of the problem.

OKay I'll check into that, but if worst comes to worst I was wondering if I could put a 2005 or newer transmission into mine From another pt cruiser. If not, what years of PT what which cars are interchangeable?
