Mercury Grand Marquis Problem Report
Mercury Grand Marquis Transmission Problems 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.
MINE WILL SLIP, WHEN GOING AT AN EVEN SLOWER SPEED, TRYING TO GO UP A GEAR, IT HUNTS FOR THE GEAR FOR AWHILE AND THE ENGINE REVS, BUT CANNOT FIND THE GEAR FOR AWHILE. THEN IT FINDS THE GEAR AND IT IS FINE. - Visitor
