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.

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.
the transmission will not go into drive only reverse.
There is a whining noise and sometime it hesitate while driving.
transmission seems to hesitate when upshifting from 30 to 45 mph. runs okay at higher speeds
Revs up before it takes off after stopping. Shifts in and out of gears as I drive.
My transmission will go in forward but not reverse
My car whining and jerks when i push the gas pedal while driving
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).
Had to pay for a new transmishion on our 2005 Merc. Grand Marquis within first year we bought from dealer in 2009. Hesitated when put in gear and slow to catch gear :( felt Taken...

Lost 3rd and 4 th gear driving a long car just rev's put into 2nd gear to get home
car whines only from 1st to 2nd gear, all other gear switches are fine.
Press gas, engine revs, but car does not go. The transmission seems to be problem.
Car wont move in drive but will reverse just fine. What could cause that?
Once in drive the car will not move
The Transmission made a loud squelling noise and now will not move into gear. would shut off.
Whenever my car is in park, when I shift it into 1st I have to rev the engine (quite a bit, I'm sure my neighbors hate it) for it to finally grab first gear. Once in gear I must keep the o/d off button on...if the car goes into overdrive it does not down shift unless again a lot of revving (while the car is moving). Any help will be great!
