2000 Mercury Grand Marquis Transmission Failure Common Due to Front Pump Failure

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.

    transmission causes car to jerk when gas is barely pressed. it runs fine at high speeds but when slowing down it jerks really hard when downshifting

  • 2000 61,000 Miles
    Whining noise in low gear, changing frequency as it slips into 2nd gear. Some of the same noise as it accelerates in 2nd gear. Not noticable after gets in 3rd and 4th. Ford dealer says it's common and not a problem as long as the car isn't loosing power. (DUH).
