Good morning gentlemen,
@BoMed1999 Are you Experiencing (Hendrix flashback for those who get it) any other symptoms? Hard shift when cold from 1st to 2nd is very common as well as bad o2 sensor readings.
How long ago did you purchase the Jeep?
The PCM could have been reset, which temporarily clears codes and symptoms.
As far as the codes you are getting...
0700 is a generic code saying something check the transmission. The other two codes:
P0740
Low transmission fluid level
Dirty transmission fluid
Faulty torque converter clutch solenoid valve
Torque converter clutch solenoid valve harness is open or shorted
Torque converter clutch solenoid valve circuit poor electrical connection
P1776
Faulty Torque Converter Clutch Solenoid Valve
Torque Converter Clutch Solenoid Valve harness is open or shorted
Torque Converter Clutch Solenoid Valve circuit poor electrical connection
Low Transmission fluid
You can call me at 866-888-7710 to discuss in further detail.
