Transmission Problems Common Due to Front Pump Failure on Mercury Grand Marquis

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.
