        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.

    • Q:

      Will this Torque Converter ( Part No. FM55B ) work in a E4OD Transmission? I have a 1995 F150 4x4 5.0L/302ci with an E4OD transmission. Looking for a cheap replacement since i am in the process of selling the vehicle.
