Buick Regal 2.5, the problem of gear jumping, has been stepping on the accelerator, almost never jumping, can jump only if it is loose, can jump in the fourth gear, but dare not refuel, and shift gears if you add a gear. 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?
