12,000 miles later, the car shifts and operates better than when I purchased it.
About a year ago, I got a transmission flush in my 2005 Mercury Sable. However, upon doing so, it became apparent that the vehicle had never had the ATF changed in its 145,000 mile lifetime. So, all the clutch material that had basically allowed the tranny to operate normally was gone. The car would not stop bucking and slipping. Someone recommended Lucas Oil Transmission Fix, and so I added copious amounts of it. 12,000 miles later, the car shifts and operates better than when I purchased it. Thanks, Lucas Oil!
