c0035 is for the right front speed sensor. probably needs a hub bearing on that side
p0420 is for the catalytic convertor. with that mileage it probably needs to be replaced.
p1811 is max adapt and long shift. is the fluid full and kinda clean? does the trans shift hard? it's probably a bad pressure control solenoid
