You need to change your reported readings/codes. The "o" should be a "0". "Oh" should be a "Zero"

However the first code indicated "3-4 shift SOL/TRANS relay circuits" The second code indicates "Cylinder #4 misfire" The third code indicates "O2 Sensor Shorted to Voltage". All according to the manual I have. Bob AZ
