There are sensors like idle air control sensor, mass air flow sensor. Is your check engine lite on? If so get the codes they will tell you the problem. Some auto

Check the brushing under the car the connect the shifted to the tranny spray them with some lube and try it, if the noise is gone replace these bushings

One question with many answers. It could be the starter,
or a good battery with dirty or bad cable connections or a
loose connection on the wire to the starter. Did the problem
occur gradually or all of a sudden? Usually the starter will
begin to warn you before it fails. A bad rotor, distributor or
alternator will not prevent the car from cranking.

PO700 is a code telling you there are codes in the TCM of some late model cars where the Transmission control module has lost connection to the PCM the vehicals main computer , And basically it happens when the TCM has a issue within itself or the transmission that sets a code and it sends a request for the PCM to illuminate the SES or CHECK engine light.
PO740 is a chrystler specific code that involves your Tourqe Converter Clutch Circuit (specifically The TCC solenoid) this code if not repaired quickly could cause major transmission problems....slipping out of gear....not shifting from first to second properly and just all around trans problems...eventually leading to no shifting at all...I highly recommend fixing it soon.

it might be easier picking up a plug at a salvage yard then just connect to the correct colors,if you have four wires two should be black and two white,

have your charging system checked, you may have a bad Altenator

PO700=Transaxel control system
PO740=Torque converter lock up. No RPM's
I would take a good look at the transmission.

In the door sill on the drivers side, there should be the model description, as well as body, trim, and paint color codes. If not, the dealer can tell you based on the last 8 of your VIN.

700= Transmission Control System
740= Torque converter clutch circuit
