Flush your car's transmission fluid , but don't do it yourself or at local shops take it to Toyota and have them replace fluid and filter . Reason why they use special pumps to extract all fluids properly . And actually replace it correctly other shops the only thing they will do is drop the oil pan and drain the fluid in the oil pan only . There is still fluid all over the lines and torque converter . Recommend dealer all the way , it's only 10-30 $. Different .besides you get genuine parts and fluids . Good luck I hope this help .

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.

#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps

Your going to have to get the car scanned for the DTC code. The Check engine light indicates that the ECM has detected an issue with the cars engine or transmission performance. Your hard shifting could be the failure to the Pressure control solenoid (PCS), that would be a DTC code P1811. The PCS is located under the trans axle side cover assembly. IF you go to Auto Zone, they can scan your car free of charge and can give you the step by step instruction to replacing the part that may have failed. Good luck and keep me posted, be glad to help.

A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.
The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.
The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.
