Transmission stopped working with no prior notice while driving on freeway at 55mph befor this happend I did not have any problems with the transmision at all it just stiopped working it seems like the gears are nor not being enguaged at all the only gear working is park. This is the wirdest thing because the transmission does not slip or leak and it pulls perfectly and shifts just fine and all of a sudden it will not go into drive or reverse

Transmission model is AX4N.The reason that the car/trans only acts up after long drives is the heat.As metal components heat up,tolerances and clearances that were marginal or borderline before with moderate heat,become excessive clearances when really hot.More than likely there are internal transmission components with excessive wear.Many problematic areas inside the AX4N trans is the pump,where the oil pump driveshaft bearing wears out,the seal is torn,and hydraulic pressure falls off,common failure point in these units.The other areas are typical to all automatic transmissions,the clutch packs and bands wear and lose clearance.as well as some of the bushings inside the unit.I just rebuilt recently a trans exactly identical to your car,V8...4.6Ltr Lincoln,and it had minimal damage inside,but enough to throw the check engine light on with a Torque Convertor Clutch trouble code.The TCC was slipping excessively,and the vehicle computer recognized this,and illuminated the CEL.Chances are good that the damage inside your trans will be minimal,but now is the time to consider rebuilding it and restoring all the hydraulic circuits integrity,and resetting all the clutch pack and band clearances with new clutches,steels,and bands.A remanufactured torque convertor should also be installed along with rebuilding the trans.Be careful as to who does the work on the trans should you decide to rebuild it,as some people's definition of a rebuild doesn't quite qualify as anything more than a patch/repair job.A complete rebuild consists of tearing the trans completely down,loading it into a parts cleaner,and thoroughly cleaning it.From this point,the rebuild begins,including a banner overhaul kit,new steels,bands,seals,thrust washers as required,Electronic Pressure Control solenoid,all new bushings,set clutch pack clearances to factory specifications,along with setting unit endplay,and a remanufactured torque convertor.Good luck.

You will have to have the solenoid body replaced in the tranny and have the PCM reprogrammed.

Unfortunately it sounds like your automatic transmission has suffered a catastrophic failure. But to be sure, allow your vehicle to warm up to normal operating temprature, pull the oil level dipstick for the transmission and check the level. It should be in the checker portion of the stick to be correct level. If it is not, adding fluid may help the condition temporarily. Check for leaks while the engine is running. Have Lincoln or transmission specialist have a look. When it comes to transmissions in general, it is best to let the pros handle it for youl

check and replace filter and fluids just like oil it tends to burn up and blacking and needs to be changed and flushed checking your tranny fluid it should be a red color not a dark red or with a black tint
