I thought there really isn't a difference betweem the 47RE and 47RH. The RE was electric but it really is only the OD that is electric which is the same as the 47RH. If I am going to need a stand alone controller I might as well get a 4r100. unless I can get a new plate for the back of the motor to mount the 47rh/re, it has an SAE #2 on the back.
