Transmission problem
1997 Plymouth Breeze Front Wheel Drive Automatic

I was driving my Breeze 97 the other day and the engine light came on and it felt like the transmission wouldn't switch gears. I was able to drive at the speed of 50 km and the engine was running at 3000 rpm. Plugged it to my obd ii computer and the code P0700, 1776 came up. I added some transmission fluid and erased the code and after that it ran fine. The car has been leaking transmission fluid for a while so I have been adding tmf regularly but it has always worked fine.
What causes the transmission to act like that?
Why does it run fine after I erased the codes?
What needs to be repaired?
Is it ok to keep on driving my car?

kind regards from Iceland

For sure you have a tranny issues and need to get it checked
what you have is a tranny related codes and its a general code to inform you that the TCM have stored tranny codes and need to be checked
an OBDII reader will not communicate with the TCM and will not get the codes, you need a scanner

run good after clearing the code that is because you taking it out of limp in mode

LIMP-IN MODE
Limp-in mode is the attempt by PCM to compensate for failure of certain components by substituting information from other sources so that vehicle can still be operated. If PCM senses incorrect data or no data at all from MAP sensor, TP sensor, ECT sensor or battery voltage, system is placed into limp-in mode and Malfunction Indicator Light (MIL) on instrument panel comes on. If faulty sensor comes back on line, PCM will resume closed loop operation. On some vehicles, MIL will remain on until ignition is shut off and vehicle is restarted. To prevent damage to catalytic converter, vehicle should NOT be driven for extended periods in limp-in mode.
