When you get a shutter- drag the brake pedal lightly-
that will turn off the torque converter clutch if the solenoid
is working

The rpm should go up with any brake pedal application-
if the converter is releasing

If you determine the torque converter clutch is bad & the
shutter,then the trans has to come out

Check engine & trans mounts also for wear

SOURCE: How do you change the transmission fluid on a 2000

you must drop the pan on the transmission, and I recommend draining the torque converter as well. you must rotate the engine by hand until the converter plug is visible in the access hole in the transmission. replace the filter and re-use the gasket if its the reusable factory gasket ( has hard inserts around each bolt hole) then re-fill the transmission through the filler tube on the right side of the engine compartment. be sure to use Mercon V fluid.

SOURCE: Transmission hesitates shifting into second and perhaps third gear when driving slow. When acceleration is positive transmission shifts smoothly. Reference "99 Mercury Transmission" as Subject when

Several things could be causing your problem:

  1. Auto transmission fluid is low
  2. Auto transmission fluid needs changing; this is an area that gets neglected by a lot of people;check the fluid and if its brown or gives off a burning smell, it needs changing. Very old transmission fluid will cause slipping in the transmission; if this is the case, it should be changed along with the filter
Hope you find that this answers your question. Best of luck.
Greg

p.s. If you have the fluid changed, make sure it's done from the tranmission pan, not through the filler tube; siphoning through the filler tube can be hazardous to the transmission, especially cars with a lot of miles

Yes there may be a recall open on this vehicle for the catalytic converter. The number is 04E12.
Go to this website and pick recalls from the left task bar and input your VIN and check to see if your vehicle is involved.

There is also a technical service bulletin out for a rattle in the catalytic converters which maybe what you are describing and this would be covered under the 8yr/80000 miles federal emissions warranty.

SOURCE: 2000 Mercury Grand Marquis has intermittent

TOOK MY 2001 GRAND MARQUIS TO THE TRANS SHOP AND OWNER, 35 YEARS IN THE BUSINESS, SAID IT WAS NOT THE TRANSMISSION. IT IS AN INTERMITTENT ELECTRICAL PROBLEM. MOST LIKELY A COIL ON PLUG THAT IS FAILING BUT NOT ENOUGH TO CAUSE THE CHECK ENGINE LIGHT TO COME ON YET. DON'T PUT ANY OF THE "FIX-IT" TRASH PRODUCT IN YOUR TRANSMISSION, CAN GUM IT UP OR DISLODGE DIRT OR METAL FRAGMENTS THAT CAN CAUSE MORE DAMAGE. SOME GARAGES HAVE COMPUTERS THAT CAN DO A STRESS TEST ON THE MOTOR TO FIND WHERE THE WEAKNESS IS LOCATED AND WHAT PART IS BEGINNING TO FAIL. IF IT IS A COIL THE PART, IF YOU ARE HANDY, YOU CAN CHANGE YOURSELF BUT EVEN IF YOU ARE NOT IT IS NOT AN EXPENSIVE DIAGNOSIS AND FIX.

I have a 1996 Mercury Gran Marquis sometimes wouldn't go into D-gear. forced me to go to 2 Gear. Few days ago when i put it on PARK gear, it goes into reverse. Do i need a new transmission?


Maybe, but not necessarily. Its possible your shift linkage/cable has loosened or stretched. Have a reputable transmission shop check that. (easy for them to do)

My 2001 grand marquis hestitates and shutters slighty when downshifting from 4th to 3rd gear, shutting off overdrive eliminates problem


The first thing to do here is to have the transmission fluid changed, the shudder is torque converter clutch chatter, just like a burned clutch in a manual transmission car. The new fluid renews the anti friction additives and in most cases eleiminates the problem, have the transmission flushed so all fluid is replaced.

Put 1 quart of dextron III/mercon in a transmission that calls for mercon v what should i do.its a 1997 mercury grand marquis


1 quart probably won`t have much of a affect on the transmission as there is about 10-12 quarts in the transmission to start with.the only way to fix it is to do a transmission service and change all the fluid and the fluid in the torque converter it has a drain plug that you will have to find so you can drain it.

2000 Mercury grand marquis has frequent intermittent shuddering, especially going up hill, and stops when ever I let off the gas or give it more gas. Also now it's starting to have delayed downshifts...


These sound like two seperate problems. The first sounds like a clogged fuel filter or faulty fuel pump. The second problem could be a bad transmission filter.

2000 Mercury Grand Marquis has intermittent shudder (almost like it is trying to shift gears rapidly and frequently while you are driving). Someone suggested a shudder fixx type product in lieu of having...


There is no transmition products that will fix a shudder that I know of.
I would suggest having tranny fluid and filter changed first as this is the most probble cause of a shudder at that milage, but if that does not fix the problem then I would have a transmition shop check the tourq converter.

ps, the fluid and filter can be changed at most quick lube or where ever you get the oil changed.

Tranny goes on neutral sometimes and then back to normal


If you happened to become high centered on something, and tried shifting from drive to reverse, you may have bent your transmission linkage, which happened to me, and I got that fixed, but it cost me 280 dollars at a transmission shop...
