(DTC) CODE # P0700....Transmission Control System (MIL Request)
Translation: Transmission Control Module (TCM) Malfunction or Failure.
P0700 Information Code
The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM.
This code is for information ONLY. If this code is present, check for transaxle codes.
P1776: Solenoid Switch Valve Latched in Low/Reverse Position. The TCM monitors the L/R solenoid to ensure that the fluid transfer happens. It uses a Pressure switch to verify this. Usually this code is set by a switch that is stuck or a solenoid that is not mechanically operating.
A transmission shop would be better suited for this type of work.

Code p1776 is solenoid switch valve latched in low/reverse position. Valve is located in valve body not solenoid body. The possibilities are:
the low/reverse pressure switch itself is bad
the transmission control relay output circuit is open
the control circuit (sense) of the l/r switch is open, shorted to ground or shorted to voltage.
The control relay's output is on pin #6 of the 8-pin plug of the transmission (red wire); you could verify that the wire has 12V on it when you are idling (and I guess I would put it in gear with the brakes applied). Also examine/shake the wire for intermittent connection possibility.
The solenoid sense circuit connects pin # 8 (light blue) to pin #50 of the transmission control module. You could check that connection and monitor it for voltage to fluctuate between 0V and some measurable V when the trans is shifting normally, and to loose that fluctuation when it is not, which would verify the circuit is OK.
If that proved to be OK, then I would suspect the switch isn't responding and needs to be changed.
The solenoid box is removable after you drop the pan and remove the valve body, and so it would not seem to be an horrendous expense (compared to a rebuild). I haven't done this myself so I can't comment on doing-it-yourself.
I would try to find a competent independent shop that know the Chrysler trans and discuss it with them as to the cost of replacing the l/r pressure switch as the alternative
The code p1784 is about the switch that monitors the hydraulic pressure for operating the low/reverse clutch of the transmission. That clutch is called into play for all forward gears as well as reverse, so it seems reasonable if that clutch were not working that the car wouldn't move in any gear. I would begin by making sure that there is sufficient trans fluid by inspecting its dipstick. If needed only use ATF +4 but don't overfill it. Also, just on a chance, take a look underneath to see if you see any motion of either the left or right half axles (or one moving, but one not) which would be another reason for no motion due to a drive shaft disconnection or some such anomaly. Other than that, your problem could be with the Low/Reverse solenoid switch in the solenoid pack portion of the transmission (the box on the driver's side of the trans) being stuck. That can be repaired without removing and rebuilding the transmission so let us hope that may be the cause. I would have the car towed to a good independent trans shop that has a reputation for knowing how to service the Chrysler electronic transmission.
DTC code p0700 is a transmission control system (mill light) which is related to the other two codes mentioned above.

Testimonial: "you was very helpful on this problem you talked in words that didn't make me fell like a dumb a// I will add this site t my fovorets for your help THA"
The last code (0498) indicates a small leak in the fuel vapour evaporative control system. Check all pipes for good connection and absence of cracks (leaks) to and from the charcoal canister. If the leak is significant you might just be able to hear the sucking noise when the engine is running. The other three codes all relate to a transmission fault. First check that the transmission has plenty of fluid on the transmission dip stick. Top it up if low. Next check that the transmission relay and its fuse are OK. Pull the transmission relay out and put back again a few times, it could be a bad connection and plugging it in and out could freshen the contacts. Check the contacts to the transmission control module and ensure that they are clean and bright. If the problem persists take it to a transmission specialist.

OBD Code 12 - No Distributor Reference Pulse (Diagnostic Test Active)
The Engine Control Module-ECM uses the distributor reference pulse to calculate the engine speed. On
newer engines, the Crank Shaft Position Sensor performs this function.
OBD Code 46 - Pass-Key II System Error - Circuit out of Frequency Range The ECM receives a signal from the Pass-Key module. When the correct signal is received, the ECM will allow the engine to start and run. Please review the RepairPal article on the GM Pass-Key Anti-theft systems for more information.
OBD Code 43 - Knock Sensor error The ECM receives a signal from the Knock Sensor based on the amount of engine ping detected. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.
OBD Code 55 - End Test.
Hope ehit help (remember comment and rated this).
