So I recently I started to notice I've been getting a hard shift between 1st to 2nd. So I went out to get the codes and came back with p0745 which was line pressure solenoid A. Does that mean I need to replace the solenoids first. I've searched before and said to check the drop resistor we'll I did and came back with 13.0 ohms I don't know if it's good or bad. I need help please.
