What Causes Power Loss After Changing Transmission Fluid?

[StQuinn]

After changing the transmission fluid, the feeling of insufficient power is caused by: fuel system issues or electrical circuit problems. Below are detailed explanations of the causes. Fuel system issues: When the vehicle's power noticeably decreases, it may be due to fuel system problems such as poor fuel injection or inadequate atomization. In severe cases, it might even prevent the vehicle from starting. These issues primarily stem from excessive carbon buildup in the fuel injectors, which can clog the injector needle valves, leading to poor fuel injection or atomization. Electrical circuit problems: Electrical circuit issues mainly include wiring problems and spark plug issues. When vehicle wiring malfunctions, it can affect the operation of certain sensors, potentially causing these problems. Additionally, spark plug issues, primarily excessive carbon buildup and aging, can also lead to insufficient vehicle power when they occur.
