It sounds like you have a problem with your crank sensor or cam sensor!! You will have to take to a dealer that knows how to learn the crank sensore.. Yes it has to be learned into the computer.

Also there was a sevice bulletn on mising being that the intake valves needed to be replaced and reseated.

The transmission code is being sent because of the randome missing.. so it will not upshift into I think 4th (lockup). and the other is sent to torque because of the random miss also..

Solution!!!!!!! take to dealer and have them relearn crank sensor!!!

Hope this helps

Ok, i wish i could tell you that there is not a problem but, i cant, there is a major issue concerning the transmission. the TCM is damaged and the torque converter signals are erratic or non existent at this time.

There is also a misfire that can be because a faulty ECM or ignition pack or coils. you will need much work done on this vehicle soon. The replacement parts are as followed.

Replace th TCM(transmissin control module)
replace the ECM/PCM
Replace the Coil Pack if damaged or the coils themselves.
replace the torque sensor circuit.

I cant seems to understand why the tech told you that their was nothing Wrong when the computer displayed all these codes. there are many issues here that are very serious concerning the transmission/ECM and ignition system.

    You have to do a crank relearn or take it to someone who can do it with a modus scanner. Just done one and it will fix the miss fire and not going into 4th gear
