Torque converter automatic transmission Mitsubishi Outlander
The torque converter is an important component of the Mitsubishi Outlander automatic transmission and is designed to transmit torque from the engine to the transmission. It performs the following main functions:
1. Hydraulic coupling
* Converts the mechanical energy of the engine into hydraulic energy.
* Allows the engine to idle without transmitting torque to the transmission.
2. Transformer
* Increases torque output at low engine speeds.
* This helps the car move away and overcome resistance while driving.
3. Hydrodynamic brake
* Creates resistance during engine braking.
* Helps slow down the car without using the brakes.
Torque converter design
The Mitsubishi Outlander automatic transmission torque converter usually consists of the following components:
* Pump wheel (turbine): Driven by the engine and creates a flow of fluid.
* Reactor wheel (stator): Located between the pump and turbine wheels and directs the flow of fluid, increasing torque.
* Turbine wheel (output): Connects to the transmission and transmits torque to it.
* Housing: Contains all torque converter components.
*Lock-up clutch: Locks the torque converter at certain speeds and gears, improving transmission efficiency.
Workflow
When the engine is running, it rotates the torque converter pump wheel. This creates a fluid flow that is directed to the reactor wheel and turbine wheel. The reaction wheel redirects the flow, creating additional torque, which is transmitted to the turbine wheel.
At low engine speeds, the torque converter acts like a transformer, increasing torque. As engine speed increases, the lockup clutch engages, locking the torque converter, reducing power loss and increasing transmission efficiency.
Types of torque converters
Depending on the Mitsubishi Outlander model, different types of torque converters can be used:
* Single-stage torque converter: Has one stage of torque conversion.
*Multi-stage torque converter: Has multiple stages of conversion for smoother gear shifting.
* Controlled Torque Converter: Equipped with an electronic control system that optimizes torque converter performance for various driving conditions.
Torque Converter Maintenance
The Mitsubishi Outlander automatic transmission torque converter usually does not require special maintenance other than regular replacement of the transmission fluid. However, if the following symptoms appear, it may require repair or replacement:
*Slippage or vibration when shifting gears
* Extraneous noise when driving
* Transmission fluid leaks
