    '97 Mercury Grand Marquis does not shift to 1st gear
    Hi,

    I have a '97 Modal Grand Marquis, and its transmission is having problems . When I shift into 'Drive' the first gear is not chosen and the 2nd starts working. 'Reverse' is working fine, and there are no problems shifting, but whenever I brake my car, it starts to vibrate. When I shift the gear into D1 it strugles in moving. I have not changed the oil yet.

    In real bad situation

    Nothing I've tried so far works, but I checked the gear oil, and it is full and is a brownish colour. All other gears work fine

    Drop and clean the pan and magnet, replace the filter, and refill with Mercon V ATF. Ford's transmission pan gaskets are reuseable and awesome. Do this ASAP. Better yet, follow the procedure below:

    How-to Easily Change All Transmission Fluid and Filter

    Example: Total Fill (13 quarts) - Initial Fill (7 quarts) = Balance (6 quarts)

    1. Disconnect transmission return cooler line, at the radiator. Look for a 6 inch length of 5/16” I.D. neoprene hose, connecting the radiator (transmission cooler) to the transmission's metal return line. Place end of hose into an empty gallon jug.

    2. Start engine and pump transmission fluid into jug, until you can hear it “slurp” in the transmission pan—the pan should now be empty. Turn engine off.

    3. Drop and clean pan with brake cleaner. Remove and clean magnet, being sure to reinstall it in the same location. Cleaning the magnet is more important than you might think, since it helps prevent metal particles from coating electro magnets in the transmission, which can affect performance. If you find what appears to be a child's toy top, discard it. It's a filler tube plug used to keep contamination out of the transmission during assembly. When the dip stick is inserted, at the factory, the plug is dislodged and remains on the bottom of the transmission pan. It is an indication the transmission fluid and filter have never been changed.

    4. Remove and replace transmission filter, coating the O-ring with ATF. Ensure the filter is completely seated in the transmission body.

    5. Replace pan. If gasket is the reusable type, reuse it.

    6. Add Initial Fill of ATF through the filler tube (7 quarts).

    7. Start engine and pump out half of Balance (3 quarts of ATF). Stop engine and add 3 more quarts of ATF.

    8. Start engine and pump out the other half of Balance (3 quarts of ATF). Stop engine and add 3 quarts of ATF. The system should now have the Total Fill of ATF (13 quarts).

    9. Replace dip stick, start engine, and, with the car level, move the gear selector through each gear (PRNDL), pausing 5 seconds in each gear. Warm car up to normal operating temperature, place car in (P)ark on a level surface, and check the dip stick with the engine running. Ensure fluid comes to the top of the “Full” line.

    I've used this procedure on other Mercury Grand Marquis and it works really well.

    I can't say that for sure. This is about all you can do, however, without taking it to the dealer. There's a 50/50 shot that this may be all that is needed.

    Does it have a 5.0. I had a 92 Lincoln Mark VII with a 5.0 H.O. with an automatic and there is a bushing on the throttle body that is connected to the a kick down cable in the transmission. I think that was a recall item a while ago you may want to check that to.

    Obviously, no one can guarantee that more serious damage hasn't taken place, especially since the fluid has turned brown. My experience has been that Ford transmissions, however, are very tough. That's especially true on Ford trucks, full size Mercurys, and crown Vics.

    My advice is to only use the same Motorcraft platinum spark plugs that originally came in the car. Change them every 50,000 miles, instead of the recommended 100,000 miles.

    Transmission fluid and filter should be changed every 30,000 miles.

    Fuel filter should be changed every 30,000 miles.

    Engine oil and filter should be changed every 5,000 miles. I recommend full synthetic engine oil; e.g. Mobil 1 or Pennzoil Platinum. With synthetics, change the oil and filter every 6,000 miles or 6 months, whichever comes first.

    Coolant should be changed every 30,000 miles. Use a 50/50 mixture of the recommended antifreeze and distilled water.

    Completely change the brake fluid every 2 to 3 years.

    Change air filter every 30,000 miles.

    Change power steering fluid every 50,000 miles (Mercon ATF).

    Change PCV Valve every 100,000 miles.

    Basically, these are Ford recommended intervals for vehicles. If you use conventional engine oil, I would change the oil and filter every 3,000 miles or 3 months, whichever comes first.
