Troubleshooting:
① The automatic tank oil pan is damaged, and all the automatic tank oil has leaked out;
② The connecting rod or locking mechanism between the shift lever and the manual valve rocker arm is loose, causing the manual valve to get stuck in neutral or parking gear;
③ The damaged pump’s oil inlet filter is clogged;
④ Severe leakage in the main oil circuit;
⑤ Resulting in pump damage.
