Common Weaknesses & Maintenance Notes.

The NSX automatic gearbox is a specialised transmission and should be carefully inspected before installation. High-mileage units can experience delayed engagement, harsh shifting, solenoid faults, worn internal components, fluid leaks, or torque-converter problems. Therefore, checking the transmission fluid, seals, shift operation, electronic controls, and internal components before installation is important. Likewise, using the correct transmission fluid and maintaining proper fluid levels can help support reliable operation.
