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: I want 2 change 2004 mercury mountaineer transmission fluid

The best way to change it is to flush it out You can do it yourself, but I do not recommend. A shop that is good like a Monro or Firestone usually charges about 100 bucks to flush and that includes the fluid. If you do it yourself, you will save about 60 dollars, but you risk damage to your radiator.

you will need a hose and an adapter. you back out the lower, or upper cooler line for your trans, whichever is the easiest to get to, (Some trucks have an auxiliary engine oil cooler, but make sure you are flushing the trans lines) put the adapter into the rad where you removed the line, and put a hose from each one down into a bucket. Have about 14 qt's of ford trans fluid ready. Put the funnel into the trans dip stick, and start the engine. pour the qts into the dipstick tube while the old fluid is pumped into the bucket. When you have about two gallons pumped into the bucket shut the engine off and reattach the line into the radiator. start up the engine and check your level. Fill with additional fluid if needed.

note: some say you should drop the pan. two things, you only change half the fluid when you do it that way, and second if you need to change the filter because it is clogged, it is too late for the transmission. The filter is only there to protect the valve body, not keep the fluid clean.

Hope this helps

SOURCE: Where is the transmission fluid drain plug for a 2000 Cougar

Your Ford has no drain plug, to change/drain the trans fluid u must remove the transmission pan, u may be able to lower fluid level with a fluid siphon pump (rated for oil) through the dipstick tube, harbor freight tools sells a pump for this purpose.

SOURCE: where are the spark plugs located on a 2000 Mercury Grand Marquis

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.

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.

My 1991 Mercury Grand Marquis will not go into reverse and the over drive does not work either what does that mean?

It sounds like your transmission need to be serviced,rebuilt or replaced.
Smell your fluid to see if it smells nasty and burned.
You can try to change the fluid and change the filter,if you do and it remains the same you need transmission service.

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.
