Regulator valve may cause noise when transmission is in reverse on Dodge Dakota

Problem Description and Possible Solution

A loud buzzing or whining noise when the transmission is in reverse may be caused by the regulator valve in the transmission valve body. A revised regulator valve was released that does not resonate. Careful diagnosis should be performed because other issues can create this same type of noise.

I had noticed for a while this noise when backing up my truck. I have not yet attempted any repair.
