I have an 03' 4.4i with about 110Kmi. I am having only one of the Transmission issues that I have read about here. I have the low-speed shudder under light throttle through the lower gears.
I can't say it always occurs, but it it frequent. There are no other noticeable problems with my transmission performance. All other shifts are very smooth and there is no noticeable slipping.
-- What are the causes of this symptom?
-- Can a fluid and filter make a difference?
-- Is this always a sign that the end is near for my Trans.?

Anyone with experience here please let me know.
