Use the TC Remanufacturing 520AA torque converter for automatic transmission systems requiring a lock-up converter with electronically modulated clutch control.

Common Issues Addressed by This Torque Converter

• Transmission slipping or shuddering during acceleration
• Poor fuel economy due to inefficient torque converter lock-up
• Delayed or harsh engagement of the torque converter clutch
• Overheating caused by excessive slippage
• Noise or vibration related to worn or damaged torque converter components

Installation Notes and Tips

Ensure the torque converter is properly seated on the transmission input shaft and aligned with the flexplate bolt holes using the 9.000 inch bolt circle. Verify the mounting pad shape and thread size (10mm x 1.5) match the vehicle’s transmission specifications. It is recommended to replace transmission fluid and filter during installation to maintain optimal performance. Follow manufacturer torque specifications for mounting bolts and confirm the pilot diameter and length fit securely within the transmission housing.
