How about regal throttle computer?

It should be the throttle position sensor. The shift logic of automatic gear is controlled by computer. The computer thinks that you want to get a higher speed by stepping on the oil deeply, so it is the same for a slow upshift and a downshift, because only a low gear can get a high torque. The computer judges the depth of the throttle through the throttle position sensor. Look at the data stream. What is the throttle opening at idle speed?
