Transmission Gear Slipping problems of the 2005 Lincoln LS

I have three major problems with my 2005 Lincoln Ls. The first problem is I have a hard reverse and the gears stick between 30-35 mph as I accelerate. Sometimes it has a hard bump once it starts accelerating! the second problem is that I have replaced two ignition coils within a year apart and now I have two more ignition coils that need to be replaced per p0354, p0301and p0304. I have replaced the throttle bottle, but the limp home sign has occured twice since then causing the car to decelerate!! the third problem is the catalytic converter per p0420. I purchased this car in 2009 with less than 50,000 miles, less than a year the transmission started slipping!.

The vehicle was driven to a mechanic shop who ran a diagnostic test and stated it was the fuel pump, abs brake sensor. All the warning lights illuminated and the repairs were done at a cost to the contact. The manufacturer was contacted who offered no other assistance. The failure mileage was 49,837. . . Mw.
