Below are detailed steps and descriptions of tools typically involved in the process. Please note that this guide is for informational purposes only and should be undertaken by a qualified professional or experienced enthusiast.

### Tools Required

– **Torque Wrench**
– Ensures that bolts are tightened to the manufacturer’s specified torque settings, preventing over-tightening or under-tightening.

– **Transmission Jack**
– A specialized jack designed to support and lower the transmission safely. It is crucial for removing and installing the transmission without causing injury or damage.

– **Socket Set (Metric)**
– A comprehensive set of sockets that fit various sizes of bolts and nuts on the transmission, typically including 10mm to 19mm sizes.

– **Ratchet and Extensions**
– Used in conjunction with the socket set to reach tight spots, allowing for easier loosening and tightening of bolts.

– **Screwdriver Set**
– both flathead and Phillips screwdrivers are needed for removing clips, connectors, and other components.

– **Pliers and Wire Cutters**
– Useful for removing clamps, cutting zip ties, or bending metal components during disassembly.

– **Fluid Pump**
– Essential for filling the transmission with new fluid after repairs, ensuring that the correct amount and type of fluid is used.

– **Transmission Fluid**
– Specific to the Mitsubishi Lancer Evolution, ensure you have the right type (often a synthetic fluid) to maintain proper operation.

– **Gasket Scraper**
– Used to remove old gasket material from the transmission case to ensure a proper seal during reassembly.

– **Cleaning Solvent and Rags**
– For cleaning parts and removing debris, ensuring that no contaminants enter the transmission during repairs.

– **Diagnostic Scanner**
– To read transmission trouble codes and understand any issues that may be affecting performance.

### Step-by-Step Automatic Transmission Repair Process

– **Gather Information**
– consult the vehicle’s service manual for specifications, torque settings, and detailed procedures specific to the Mitsubishi Lancer Evolution’s automatic transmission.

– **Prepare the Vehicle**
– Ensure the vehicle is on a level surface and secure it with wheel chocks. Raise the car on jack stands to provide enough clearance to work underneath.

– **Disconnect the Battery**
– Always disconnect the negative terminal of the battery to avoid any electrical shorts or shocks while working on the vehicle.

– **Drain the Transmission Fluid**
– Locate the transmission drain pan and remove the drain plug. Allow the fluid to completely drain into a suitable container.

– **Remove the Transmission**
– Use the transmission jack to support the transmission. Disconnect any linkages, electrical connectors, and fluid lines attached to the transmission.
– Unbolt the transmission from the engine and carefully lower it from the vehicle.

– **Disassemble the Transmission**
– Once on a clean work surface, remove the transmission pan using the socket set. Take care to keep track of any bolts and components.
– Remove the filter and any internal components according to the service manual, noting their arrangement for reassembly.

– **Inspect Components**
– Carefully inspect gears, clutches, and other internal components for wear or damage. Look for metal shavings or discoloration in the fluid, which may indicate serious issues.

– **Replace Damaged Parts**
– Order download MITSUBISHI Lancer Evolution workshop manual and replace any worn or damaged parts, such as clutches, seals, gaskets, or solenoids. It’s best to replace the filter and gasket during this process.

– **Clean the Transmission Case**
– Use a gasket scraper to remove old gasket material and clean the mating surfaces. Wipe down all internal components with a clean rag and solvent to remove any debris.

– **Reassemble the Transmission**
– Reinstall the filter and any other components in the reverse order of disassembly, ensuring all parts are correctly seated and torqued to specifications.

– **Reinstall the Transmission**
– Lift the transmission back into place using the transmission jack. Align it with the engine and secure it with bolts, reattaching any linkages, electrical connectors, and fluid lines.

– **Refill Transmission Fluid**
– Use a fluid pump to refill the transmission with the appropriate type and amount of fluid. Follow the manufacturer’s recommendations for checking fluid levels.

– **Reconnect the Battery**
– Once everything is reassembled, reconnect the battery and clear any diagnostic codes from the system.

– **Test Drive**
– Start the vehicle and let it idle for a few minutes. Check for leaks and ensure the transmission engages smoothly in all gears. Take the vehicle for a test drive to verify that everything is functioning correctly.

### Final Notes

– **Safety Precautions**
– Always wear safety glasses and gloves while working on the vehicle to protect yourself from sharp edges and fluids.

– **Professional Help**
– If you are unsure about any steps in this process or lack the proper tools, consider seeking help from a professional mechanic.

This guide provides an overview of the steps and tools involved in repairing an automatic transmission on a Mitsubishi Lancer Evolution. Each step may vary in complexity based on the specific issue with the transmission. Always refer to the service manual for detailed instructions tailored to the vehicle model.
The Positive Crankcase Ventilation (PCV) valve is a crucial component in internal combustion engines, playing a significant role in both engine performance and emissions control. It is designed to manage the pressure and gases that accumulate in the crankcase, which is the area of the engine that houses the crankshaft, connecting rods, and oil. As the engine operates, combustion gases can leak past the piston rings into the crankcase, creating pressure and potentially leading to oil leaks and increased emissions.

The PCV valve serves as a one-way valve, facilitating the flow of these gases back into the intake manifold, where they can be reintroduced into the combustion process. By doing this, the PCV system helps to reduce harmful emissions by preventing the release of unburned hydrocarbons into the atmosphere. Furthermore, it aids in maintaining optimal pressure within the crankcase, which is essential for proper lubrication and overall engine longevity.

When functioning correctly, the PCV valve improves fuel efficiency and reduces the likelihood of engine knocking. However, over time, the valve can become clogged or stuck, leading to issues such as excessive oil consumption, increased emissions, or even engine damage. Regular maintenance and inspection of the PCV valve are essential to ensure the engine runs efficiently and meets environmental standards. Overall, the PCV valve is a small but vital component that contributes significantly to the health and efficiency of an engine.
