The advisor told me that this is caused because the trans fluid they were using is hygroscopic (susceptible to absorbing water) and this would then lead to the clutch plates chattering. He assured me that they now have a new non-hygroscopic fluid that is supposed to be the end of this issue. Furthermore, according to his source, changing the torque converter as others have done does not truly fix the problem. It was only because they also changed the trans fluid when they changed the torque converter that it seemed to fix it. He didn't give me the name or part # of the new trans fluid but I'll try to get that info if I can.

I just had the flush done with the newer Mobil 1 fluid. This is not a guaranteed fix. Torque converter may still be necessary even with newer fluid. Trying now to get mine back in the shop for converter.
