The utility model discloses oil way systems capable of achieving limp home and used on a hydraulic-control automatic mechanical transmission (AMT) and a double-clutch transmission (DCT). According to the oil way system capable of achieving limp home and used on the hydraulic-control automatic mechanical transmission, a hand-operated valve, a third switching valve, a third mechanical valve, a forth mechanical valve, a fifth mechanical valve and a corresponding hydraulic oil way are added on the oil way of the TMT; the third switching valve, the third mechanical valve and the forth mechanical valve are responsible for oil way switching between a normal working mode and a limp home mode; the hand-operated valve is used for distinguishing gears of P/R/N/D and switching the oil way under the limp home mode; the fifth mechanical valve is used for controlling the clutch of the limp home mode. The utility model further discloses the oil way system capable of achieving limp home and used on the double-clutch transmiss
