No over filling is not a good idea, Jack up so fill point is the high point(so one wheel on the ground the other lifted), & fill like that, as suggested then run through all gears several times, recheck level, lower car & take for a short run(enough to get to running temp), making sure u run it in all gear & manual mode-important, bring back put on a level surface & recheck oil level(level check should be done on flat level surface@operating temp) the other investment u should make is the dongle for FORSCAN(LINKER LS or OBDLINK EX are the two best & recommend by FORSCAN) Then it gives u the opportunity to reset the TCMs learning parameters which will reset shift points & pressures(when resetting there is a learning process to correctly relearn shift & shift pressures-best done at a quiet time & a place with not much traffic to start off) basically start off with limited throttle & gradually run it through the gears until top gear is achieved then let it coast to a stop without using brakes if u can, then repeat this using different throttle inputs, until eventually a few free spirited runs (I like to use an on ramp of a freeway/motorway).....but in the end the condition that u described your transmission in when u serviced it it could be also the the clutchs also have significant wear & have done there day, as Ford also recommends 60k service intervals for these transmission....
