Use only Mitsubishi-approved ATF SP-III fluid. Additionally, monitor the transmission control module (TCM) for error codes and address any issues promptly to prevent long-term damage.
Q3 How do I replace the INVEC transmission in a 1994-2001 Mitsubishi 3000GT?
How do I replace the INVEC transmission in a 1994-2001 Mitsubishi 3000GT?
Replacing the INVEC transmission involves disconnecting the battery, removing the driveshaft, and detaching the transmission mounts. Drain the transmission fluid, disconnect the wiring harness, and unbolt the transmission from the engine. Carefully lower the transmission using a jack and install the new unit in reverse order. Ensure proper alignment and torque specifications during reassembly.
Q4 What should I do if my INVEC transmission is not shifting properly?
What should I do if my INVEC transmission is not shifting properly?
If your INVEC transmission is not shifting properly, start by checking the transmission fluid level and condition. Low or contaminated fluid can cause shifting issues. Inspect the shift solenoids and wiring for damage. Use an OBD-II scanner to check for error codes from the TCM. If no issues are found, consider consulting a professional for further diagnostics.
Q5 How can I optimize the performance of my INVEC transmission?
How can I optimize the performance of my INVEC transmission?
To optimize performance, ensure regular fluid changes with Mitsubishi-approved ATF SP-III. Upgrade to a high-performance torque converter for better acceleration. Consider installing a transmission cooler to reduce heat buildup during aggressive driving. Regularly inspect and maintain the TCM and shift solenoids to ensure smooth operation and longevity.
