I've got a 2000 F150 5.4L 2V 210000 miles that has a bad head gasket and intake man gasket. I've decided to pull the motor and have it rebuilt. My question is should I replace the torque converter while I've got it out or save the money? I wasn't having any transmission related trouble but I've been told that while I had it out I might as well replace it. I've had others say reinstall the old one if I wasnt having any trouble with it, Recommendations??
