Common Questions
Find answers to common questions about torque specifications
Q1 Is the transmission compatible with all 2000-2007 Mitsubishi Lancer models?
Is the transmission compatible with all 2000-2007 Mitsubishi Lancer models?
The INVEC transmission is compatible with most 2000-2007 Mitsubishi Lancer models, including the ES, LS, and OZ Rally editions. However, compatibility may vary based on engine type (e.g., 1.8L or 2.0L) and drivetrain (FWD or AWD). Always verify the specific transmission model number with your vehicle’s VIN or consult the manufacturer’s compatibility chart to ensure proper fitment.
Q2 What are the maintenance requirements for the INVEC transmission?
What are the maintenance requirements for the INVEC transmission?
Regular maintenance for the INVEC transmission includes checking and replacing transmission fluid every 30,000 to 60,000 miles, inspecting for leaks, and ensuring the transmission filter is clean. Use only Mitsubishi-approved transmission fluid (e.g., DiaQueen ATF SP-III). Additionally, monitor for unusual noises or shifting issues, and have the transmission serviced by a certified technician if problems arise.
Q3 How do I replace the INVEC transmission in my Mitsubishi Lancer?
How do I replace the INVEC transmission in my Mitsubishi Lancer?
To replace the INVEC transmission, start by safely lifting the vehicle and removing the battery and air intake. Disconnect the driveshaft, shift linkage, and electrical connectors. Drain the transmission fluid and remove the transmission mount bolts. Use a transmission jack to lower the old transmission and install the new one, ensuring proper alignment. Reconnect all components, refill with transmission fluid, and test for proper operation.
Q4 What should I do if my INVEC transmission is slipping or not shifting properly?
What should I do if my INVEC transmission is slipping or not shifting properly?
If your INVEC transmission is slipping or not shifting correctly, first check the transmission fluid level and condition. Low or contaminated fluid can cause these issues. Inspect for leaks or damaged components. If the problem persists, use a diagnostic scanner to check for error codes. Common solutions include replacing the transmission fluid, repairing leaks, or addressing faulty sensors or solenoids.
Q5 How can I optimize the performance of my INVEC transmission?
How can I optimize the performance of my INVEC transmission?
To optimize INVEC transmission performance, ensure regular fluid changes using Mitsubishi-approved ATF. Avoid aggressive driving and sudden shifts. Install an aftermarket transmission cooler for better heat dissipation. Regularly inspect and maintain related components like the torque converter and shift solenoids. Additionally, reset the transmission control module (TCM) to adapt to driving conditions for smoother operation.
