Something is, or thinks that it is overheating? Do you drive the vehicle in AutoStick mode?
First check the ATF fluid level. Radiator fan working? (I seem to remember that you had previous problems with this).
ATF cooler functioning OK?

P1797-MANUAL SHIFT OVERHEAT

The major cause of heat build up in the transmission is torque converter slip. With the transmission in the AutoStick® mode, the torque converter can slip during aggressive driving or heavy loading conditions such as trailer towing or driving up steep grades. In the non AutoStick® mode, internal controller logic prevents the transmission from overheating by managing the shift and EMCC schedule. In the AutoStick® mode, when the transmission or engine temperature approaches an overheat condition, the manual shift overheat DTC sets and the AutoStick® mode is temporarily suspended until the temperature returns to normal.

The ESC light being on may be related. The fault code for that should be stored in the ABS module. It would help to know that code also.

The ESC (electronic stability control) resides in the ABS (anti-lock brake module). See if you can get someone to read the code(s).
If this 'hard shifting out of Park' problem began after the brake switch replacement, I think that the switch installation may be the cause. I would have whoever performed the switch replacement to review the installation/adjustment.
The ESC system and fault code P1797 don't seem related to the Brake-Transmission Shift Interlock (BTSI) circuit whatsoever.

A failed clockspring would light the AIRBAG light and maybe you would lose steering wheel controls like horn, cruise control and radio controls.
The clockspring might also have the steering wheel angle sensor in it that the ESC depends on for steering wheel input information during an emergency maneuver.

P0572, P0703 and C1000 are all brake switch codes. Are these old codes from before the switch was replaced? Or have these codes set since the switch was replaced?
The P0572 and P0703 may have a 'starts since set' listed that you can see on the scan tool. This might give an idea of how long these codes have been stored in the module.
Better erase them and see what comes back.

P0572 -Brake Switch 1 Stuck On
C1000 - Brake Pedal Switch 1 Circuit Performance
P0703 CHRYSLER - Brake Switch Performance

I still think that your 'hard to get out of Park' problem is due to a brake switch issue. Make sure that your brake taillights in the rear work.

If you don't buy a Mopar brand switch, you want an OEM replacement switch to ensure proper fit and operation.
O'Reilly's offers 3 brake light switches for your vehicle. The MasterPro Ignition (MPI) brand is the only one that says that it is OEM. The 2 BWD brands say nothing about being OEM. Avoid non-OEM parts:
List: Stoplight Switch - 2011 Dodge Grand Caravan | O'Reilly Auto Parts (at http://www.oreillyauto.com/site/c/search/Stoplight+Switch/02071/C0039.oap?year=2011&make=Dodge&model=Grand+Caravan&vi=1504646 )
The switch is non-adjustable, but if it isn't installed correctly you will have problems. Once the plunger sets to the brake pedal height with the pedal resting on its upstop, that is the adjustment.

You should have a 3rd liftgate mounted brake light (LED, not bulbs).
We called them CHMSL (center high mounted stop light)

The brake switch is actually 3 switches in one.
1) The rear brake lamps get power when pressing the pedal and not have power with your foot off the pedal.
2) The cruise control should lose power when pressing the pedal, but get power when your foot is off the pedal.
3) The PCM should see a ground signal when pressing the pedal, but not see a ground with your foot off the pedal.
