i have a 2000 lincoln conti, and its in great shape..its very fast too(2 fast)!,i noticed that when accelerating hard,the car kinda jerks,like if you were pressing the brakes a little and then letting go. its not very noticeable but just enough to let me notice. i dont know if the previous owner did a atf fluid change,,,right now, it looks not very dirty and im tempted to do a atf change,but im afraid of doing it because they say that it could hurt the transmission...help! oh! by the way!!! the car has 121000 miles on it!
