What Are the Symptoms of Transmission Slippage?
1 Answers
Transmission slippage symptoms: When starting, pressing the accelerator pedal results in high engine RPM but slow vehicle movement; during driving, pressing the accelerator deeply leads to slow acceleration; when climbing a slope, the engine RPM is high but the vehicle moves slowly; when shifting into a certain gear while driving, the engine RPM suddenly increases but the vehicle speed rises slowly. Here are the related details: 1. The feeling of transmission slippage: Transmission slippage is accompanied by jerking. When pressing the accelerator, the engine responds quickly, and the RPM rises rapidly, but there is no sense of acceleration, giving a feeling similar to pressing the accelerator in neutral. 2. Reasons for transmission slippage: (1) Severe wear of the clutch, brake, or one-way clutch, excessive clearance of the clutch plates, leading to slippage. (2) Overfilling of transmission fluid, which generates a large amount of bubbles when vigorously stirred by planetary gears during operation, causing slippage. (3) Use of non-specified transmission fluid, as some inferior fluids can accelerate the aging, swelling, or failure of internal seals, resulting in slippage. (4) Low main oil pressure causing slippage. If the automatic transmission fluid level is too low, the filter is clogged, the oil pump is severely worn, the main oil circuit is leaking, or the main pressure regulator or pressure control solenoid valve is faulty, the main oil pressure will be too low, leading to slippage and burning of multiple actuating components.
