Performance test device for transmission valve of automatic transmission

The invention provides a performance test device for a transmission valve of an automatic transmission. The performance test device is applied to the technical field of automatic transmission components. One end of an oil outlet path (2) of the performance test device for the transmission valve of the automatic transmission is communicated with an oil tank (1), and the other end of the oil outlet path (2) is communicated with one end of a first oil branch (7) and one end of a second oil branch (4) at the same time; the other end of the first oil branch (7) is connected with a clutch valve (5) of the transmission valve, and the other end of the second oil branch (4) is communicated with a gear selecting and shifting valve (6) of the transmission valve; the clutch valve (5) and the gear selecting and shifting valve (6) are communicated with one end of an oil returning path (3), and the other end of the oil returning path (3) is communicated with the oil tank (1); and the clutch valve (5) and the gear selecting and shifting valve (6) are connected with a control component (36). The performance test device for the transmission valve is simple in structure and convenient to operate, has multiple test functions, and is small in equipment investment, high in generality, and high in utilization rate, and the cost is saved.
