P0403 - a fault with the EGR solenoid circuit.
P0700 - an indication of transmisison trouble codes.
P1776 - Solenoid switch vale latched in L-R position.
Possible causes are :
Low battery voltage.
Excessive debris in transaxle pan.
Valve body damage.
I would suggest starting with a test on the charging system and battery.
To check for debris in oil pan and clogging of filter, you need to drop the oil pan.
