Why Does the Transmission Have Shift Shock?
1 Answers
Transmission shift shock is a particularly challenging and complex type of fault in automatic transmissions, involving a wide range of issues and numerous potential failure points, making troubleshooting difficult. The following factors can influence shift shock faults: 1. Mechanical faults: such as improper assembly clearance of automatic transmission friction plates, improperly installed snap rings, etc. 2. Hydraulic circuit faults: such as improper adjustment of the throttle cable, misaligned steel balls in the valve body, incorrect accumulator oil pressure adjustment, blocked shift valve or sequence valve circuits, unsynchronized brakes and clutches, excessive wear of throttle orifices, etc. 3. Electrical circuit faults: such as faults in the throttle position sensor, flow sensor, vehicle speed sensor, or shift solenoid valves.
