I had an 87 Ford t bird with several noise and hesitation problems. Tranny resisted shifting, rod starting to knock and cam tappets wearing out. 154,582 miles and I dropped in oil stabilizer and transmission fix and the car drove smooth and quiet for another 129,759 almost trouble free miles. I say Almost because it was after all an 80's Ford. I now swear by all Lucas products. -Mathew Hamel
