OK, I had in the shop yesterday and they really didn't figure anything out. It would not do it all the time. They are speculating that it could be the torque converter. It doesn't shift hard or nothing seems to be wrong with the transmission. Can the torque converter whine like that with no other symptoms being wrong with the transmission.
They are going to go ahead and change the fluid and add some additive to it and see what that does.
What other info do you guys need to know?
