How can I fix this? My manual says to use the gears 1 2 & 3 because its takes off so very slow in drive (D) , I was using the lighter at the time when it all stopped working, so is that the problem? B

check wiring behind each cig lighter or use test light inside the socket

SOURCE: TRANSMISSION PULLS VERY VERY SLOW IN DRIVE AND ONLY WHEN I ACCELERATE HEAVILY. REVERSE WORKS FINE.

is this car still under warranty? if so take it back to the dealer and don't accept it as repaired till you drive it. sounds like the logic that controls the transmission is flipping out, sometimes they will tell you that it needs a reflash. what this amounts to is that the manufacturer put some not so great programming in the logic when they built the car but now they have a patch or fix that makes it work better but you have to pay them for their time to install the fix. ask them what they will charge you for the privilege and decide if it's worth it to you. there is a recorded technical service bulletin about harsh shifts for your car. well, actually there are two, the latest one a revision of the first. i would try to make this their problem, it really is. hope this helps.

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

First check your tranny fluid levels.
If it is too high or too low this could be your problem and easy to fix.
If the levels are fine it could mean that it's either engine mounts,CV joint,U-joint...in this case you would need to see a mechanic.

Hope this helps.
