        Hi Al, my answer to your question on the Pro-King Automatic Transmission Remanufactured Torque Converter - part# FM55B is that a bad TCC (Torque Converter Clutch) lockup circuit or a bad TCC clutch may be the possible cause of the problem on your vehicle. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.
