Reasons for Severe Gear Shifting Jerks in Ford Edge Transmission
2 Answers
Here are the reasons for transmission jerks: 1. Clogging by dirt and impurities: Stubborn dirt and impurities accumulate inside, especially within the valve body, forming blockages that prevent effective oil pressure regulation, leading to jerking, impact, and slippage issues. 2. Transmission overheating: High temperatures degrade the quality and frictional properties of automatic transmission fluid, increasing friction wear and transmission noise. It also generates internal impurities or sludge, causing transmission jerks and impacts. If temperatures exceed 120°C, rubber sealing materials begin to harden, crack, and eventually leak, reducing hydraulic pressure. 3. Transmission slippage: When the transmission starts slipping, it raises temperatures, resulting in jerks. If not addressed promptly, the transmission may become irreparable.
As a long-term owner of the Ford Edge, I have personally experienced severe transmission jerking issues, which are mostly caused by stuck or worn solenoid valves, especially noticeable during startup and gear shifts. Aging or insufficient transmission fluid can also lead to unstable oil pressure, resulting in sluggish response and worsened jerking during acceleration. Another common cause is outdated or buggy control module software, requiring timely system updates to prevent logic errors. If the clutch plates are worn or sensors malfunction, it can further cause uncomfortable vehicle shaking. It is recommended to regularly check and replace transmission fluid, adhere to maintenance schedules, and visit professional workshops to scan for error codes with diagnostic tools for quick problem identification and to avoid bigger troubles.
