Transmission will not go in any gear
This a pressure fault with the low/reverse circuit and the over drive circuit. Check wires to the transmission they may be pinch and touching each other or grounded to the body or vehicle power. with a scan tool reading transmission pids and a external pressure gauge can confirm what is wrong. Of course we checked the transmission fluid it is full hot idling in neutral.

I WOULD TRY REPLACING THE INPUT SPEED SENSOR..A DEFECTIVE SPEED SENSOR CAN CAUSE ALL OF THESE FAULTS..IT IS LOCATED IN FRONT OF TRANS ABOVE SOLENOID PACK..IT IS THE ONE CLOSEST TO THE ENGINE..IT SCREWS INTO TO TRANSMISSION..A 1 INCH SOCKET FITS IT..ALSO CHECK WIRING TO BOTH SPEED SENSORS..A SENSOR IS ABOUT 35 BUCKS,AVAILABLE AT YOUR LOCAL DODGE DEALER..GET A NEW ONE AND YOU'LL SEE WHAT IT LOOKS LIKE..FAIRLY COMMON PROBLEM..HAVE REPLACED LOTS OF THEM

You will have to check your OD relay and fuse. Then take a peak underneath at the overdrive solenoid. This should have a single wire connected to it and it will be about the size of an old Tomato paste can. Put your hand on it and have someone else push the overdrive button with the key in the run position but, not , running. If you feel a clicking or tapping motion, you may want to remove the solenoid and clean the throw rod with a aercsol spray such as carb cleaner or even better Brakleen because this one leaves no film. At the worst case, you'll have to replace the solenoid.

The Po700 code means that something is wrong with your transmission control module. The Po841 code means that your filter may be loose. Click on the link below to read more:

Your scanner will give you the code but it will not tell you how to fix your vehicle. Scanners basically tell you what systems to check or what systems are failing.
These are what your codes mean:
P0700: Transmission Control Module
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module. This is just a informative code.
P0734: Gear ratio error in 4th gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit
P0732: Gear ratio error in 2nd gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit
P0731: Gear ratio error in 1st gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit
P0871: Transmission Fluid Pressure Sensor Switch C
P0876: Transmission Fluid Pressure Sensor Switch D
Emissions Codes:
P0400: Exhaust Gas Recirculation Flow Malfunction
- Harness or connectors (EGR volume control valve circuit is open or shorted.)
- EGR volume control valve stuck closed
- EGR volume control solenoid valve
- Dead (Weak) battery
- EGR temperature sensor and circuit
- EGR Valve
How to fix :
- Clean EGR Valve
- Repair EGR harness or connector
- Replaced EGR volume control solenoid valve
- Replaced EGR volume control valve
P0440: EVAP Emission Control System Malfunction
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister
P0456: EVAP Control System Leak Detected (Very Small Leak)
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister
P0441: EVAP Emission Control System Incorrect Purge
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister
Based on the info check your EVAP system. I would check for leaks and maybe replace the EGR and the canister.
For the transmission check the TCM also you may need to take it to a mechanic though.
Hope this helps a little.
