What Causes the Vehicle's RPM to Not Exceed 3000?

[OKiara]

When the vehicle's engine RPM cannot exceed 3000, it is mostly due to a malfunction in the automatic transmission. Common issues such as transmission slippage can lead to this situation. Additionally, using an inappropriate gear or not releasing the handbrake can also result in high RPM without a corresponding increase in speed. Therefore, it is necessary to first rule out these factors. The following are the causes of transmission slippage: Check the Transmission Fluid Level: If the fluid level is too low or too high, or if there is a transmission fluid leak, the oil pump may draw in air, leading to poor lubrication and incomplete operation, which can cause slippage. Check the Quality of the Transmission Fluid: It is also important to inspect the quality of the transmission fluid. If the fluid appears dark brown or has a burnt smell, it indicates that the transmission fluid is dirty or clogging the oil passages. Testing for Transmission Slippage: Move the gear selector into different positions and drive the vehicle. If the automatic transmission shifts into a certain gear and the engine RPM suddenly increases without a corresponding increase in vehicle speed, it indicates slippage in that gear.
