Question about 2005 Lincoln Aviator
2005 lincoln aviator: check transmission comes on when I accelarate over bumpy terrain,it also revs up higher when changing gears. Once I turn the truck off and back on the light is gone, and everything is back to normal. it happen every so often. Why?
Most likely it is time for a tranny rebuild.
When you turn car off and then back on after a few minutes, the computer resets and it feels like the problem is gone.
soon, it will happen more often.
have a local tranny shop look at it. I did mine for $1,500. Shop around.

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.

First check your tranny fluid levels.
If it is too high or too low this could be your problem and easy to fix.
If the levels are fine it could mean that it's either engine mounts,CV joint,U-joint...in this case you would need to see a mechanic.
Hope this helps.
