I understand that if the bands are gone, the problem should be present most of the time. If the malfuctioning is erratic or sporadic you should look the other way. I had my tran "overhauled" ?which is costly?just to find out later the responsible for the irregular behavior of the tran it was something called MLP sensor ?it controls the tran in some aspects.
Have you heard about this MLP part?
