First check if there is any oil in the gearbox and if the oil inlet line is blocked, then check the transmission oil sump and the torque converter filter. If metal fragments or the like are found, it is certain that the components inside the large overrunning clutch in the transmission are damaged. If aluminum scrap is found in the transmission sump and the torque converter filter, it is certain that the parts inside the torque converter are damaged. At this time, the gearbox and torque converter must be disassembled to repair and replace the damaged parts. Excluding the above reasons, the car can still not walk, it can be determined that the bolt around the second gear member in the gearbox is cut off, or the intermediate shaft output gear is off, so that the power cannot be output. Remedy: The 8-shaped end cover of the gearbox can be disassembled, the second gear member can be taken out, and the cut bolt can be replaced. This bolt material is 40Cr, it must be quenched and tempered, and it can never be replaced by ordinary bolts.
