Had a tranny rebuild at 150K on this 260K beauty. It has developed a slight issue. While moving from a stop, and speeding up, I hear a slight continuous scraping noise from the tranny. It exists in all gears and STOPS when the torque converter locks up. Now I know that touching the brake pedal unlocks the converter. When I press the brake to make the brake switch, the noise comes back. Release the brake and the noise goes away. So I connected a switch to break the circuit so I can unlock the converter without touching the brake.  Press the switch and theres the noise. Releasem it goes away. Sounds like the converter is going bad. No? No other shifting problems other than this.

what do you think?
