If a large amount of hydraulic oil sprays out from the pressure test hole, it indicates that the main oil circuit pressure is normal, and the fault lies in the input shaft, planetary gear set, or output shaft of the automatic transmission. Check whether the linkage or cable between the automatic transmission control lever and the manual valve rocker arm is loose. If it is loose, it should be reinstalled. If only a small amount of hydraulic oil flows out from the main oil circuit pressure test hole, the oil pressure is very low or basically non-existent, the oil pan should be opened for inspection.
