To be absolutely sure of the need to replace these items, you will need to use a factory can tool and diagnostic procedure to test them; there really is no other way to check operation. I do agree with the specialist in his reply to you other question however, the TCC diagnosis is very likely the cause of the symptoms you are having. Of course any repair technician that you take the vehicle to for correction of the problem will want to do his own diagnosis of the problem anyway, so that he can stand behind his work.
Replacing a TCC solenoid and screen, inside of the valve body in teh transmission on this vehicle, really is not a job that you want to attempt yourself if you are not familiar with transmission repair.
