Hi David. I am a big fan of starting with the cheap and simple fixes first. Some people find that a low transmission fluid level caused the problem you described and when they simply added a little transmission fluid, they solved the problem. Like your car oil, transmission oil can get dirty, only with transmission fluid, dirt can clog the filter and the control body of the tranny system. About 70 % of all the auto tranny problems are solved by changing the transmission fluid.
However, on a Lincoln site, one person stated: "I had my tranny fluid changed which made it shift even harder. the mechanic told me to take it to Ford and have them reset the computer. So I pulled the battery cable off for a minute and put it back on to reset the computer. Now the car shifts like it should... Try this first, its free".
On the Lincoln forum, Tom stated, " the Transmission Pressure Control Solenoid Pack needs to be replaced. This seems to be a common issue on the transmission you have. There are 3 pressure control solenoids & 4 shift solenoids in one plastic part ,made by Bosch. You remove the trans pan,the gasket is reuseable silicone You remove the filter, You remove approx 7 -- T30 bolts, holding the solenoid pack & one 10mm electrical connector bolt. HPN-9L2Z7G391A about $400 for the part and add on labor. Add in some new Mercon V and filter kit and your good to go. " Good luck.
