Hi I'm litoshop on your vehicle you have 5 mounts front left side, front right side, lower strut rear of engine,upper strut right side and transaxle rear left side good luck if this information has been helpful please let use know thank you

The first thing you need to be aware of is that fault codes do not tell you exactly what is wrong with the car and never indicate specific parts have failed. Fault codes only give an indication as to what circuit or system is behaving abnormally at the time.
The fault code P0700 from your engine control module means that there are fault code(s) stored in the transmission module as well. it is not an indication of a problem in itself; it is just a flag to alert the technician that he needs to scan the transmission controller for faults.
For the couple of model years i checked, there was no valid definition for a P0731 on the neon model. If you give me the exact year of the vehicle, i can check to see if there is a definition for this code for your car, but i can tell you that being a 700 series code it is going to be related to transmission operation.
To diagnose this type of fault code is going to require access to a professional level scan tool that is capable of accessing the trans control module for fault codes and stored data. O nce the codes from the transmission are read, then there will be a manufacturer's test procedure to follow to test operation of the specific circuits and components related to that code. This again is going to require a DRB-III scan tool or equivalent to display live transmission data as well as to run the test sequences involved in diagnosing whatever code is stored there.
So, for this reason my answer to your question would be that you should take this particular problem in to a shop with the required test equipment and a technician trained in Chrysler transmission diagnostics to be looked at before attempting any kind of repairs yourself. Some things can easily be diagnosed and repaired at home in the driveway with minimal equipment; this particular type of fault is not one of them.

SOURCE: CODES P0300 P0303

These codes are codes regarding failure. The code P0300 means repeated Engine Misfiring. The code P0303 means Repeated Misfiring of Cylinder Number 3. Kindly contact a technician to get both checked. Their Heads must have been misplaced or broken due to misfiring.
Thank you sir, Have a nice day.

miss fire codes need to check tune-up, proper spark at all cylinders

SOURCE: my 2004 dodge neon sxt is giving me a p0340 code

A code P0340 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed

• Visually inspect all the wiring and connectors in the circuit
• Check for continuity in the circuit wiring
• Check the operation (voltage) of the camshaft position sensor
• Replace the camshaft position sensor as required
• Check the crankshaft position circuit as well
• Replace circuit wiring and/or connectors as required
• Diagnose/replace the PCM as required
