Codes showed P0101 and P1778. I changed the Massive Airflow Sensor for about $130 but it didn't help.

Sent car to Valley Automotive Repair and Electric (425-310-4788) towed by Maple Valley Towing (Jason) 425-433-0516.

Their evaluation fee is $175 to $275.

They said the transmission is bad. The remanufactured transmission plus towing came to about $6200. They are trying to find a used transmission instead, with a total cost closer to $5100 [3/17/2022]

I accepted their suggestion to spend about $100 to do a quick analysis to make sure the rest of the car is OK so that we don't throw this money for the transmission to avoid another unforeseen cost.
