By the mid-1990s, Ford had converted what was once a vehicle only found on job sites and farms, to a vehicle that was being used as a family car.
Signs of a faulty converter include transmission slippage, shuddering and delayed shifting. It was also found in the pickup truck. There's also one hidden cost: If the torque converter gets replaced, then the entire transmission and its cooler should be thoroughly flushed and the filter replaced. As the assembly contains a part with a lot of clutches, when it goes bad, a rattling noise can be heard, even while the vehicle is in park.
