2002 neon trans pressure swithc code P08884

Your alternator might be bad also, or the crank sensor

I don't know but if you can again check for the ODB2 diagnostic code it might provide some light on the problem

I hope this helps.

have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy

I would guess that something inside of the transmission has failed and there is no longer a mechanical connection between the motor and the drive axles regardless of what gear you attempt to move in.[sheared splines, broken planetary, etc.] Often when this happens you won't hear any kind of noise because of the failed parts being inside the transmission case...instead the car just won't go anymore. You could have a CV drive axle joint that has failed but generally they will make some noticable rattling or grinding noise as they churn away when you try to go forward or reverse. If something has failed inside of the transmission then the transmission will need to be removed and repaired. It if is just a drive axle joint that has failed then that can be replaced without doing anything to the transmission. Hope this helps and good luck!

Check the anti-theft module and relay

If the engine is reving but car not accellerating , then yes , it is the trans if an Auto , or the clutch if it is a standard.
If you are just not able to get any power out of the engine , I would suspect Fuel filter.

no, adjust the throttle valve cable for the trans and it should get better

replace the input and output speed sensors

sounds like the intake hose from throttle body is not on intake manifold properly..as for the p0700 trouble code,you need trans controller scanned for fault codes..let me know what codes are in trans controller

The MAP sensor and Knock Sensor are both very easily replaced. A better scanner will tell you which sensor is going bad on your transmission. An Autozone code reader will not tell you which sensor on the trans. is acting up. Most sensors on your trans. are very easity replaced as well. They just screw in and plug it. It's worth paying to get a "real" scan done. The trans. sensors are inexpensive and you can replace any other your listed sensors yourself.
