I am having a new problem with my 2002 47RE Tranny. At 55 / 60 mph the tach will rev up 100/200rpm in OD if I get on it to pass, say on a small grade.
I have read all the post here about TC failure and the "hunting" 3rd/OD problem and can not find a match to my problem. NO SHUDDER!! on mine, just a rev up of the engine and then the revs adjust back as I accelerate.
I am running an edge EZ on a stock truck.

 

Could be the TC cycling in and out of lockup.

Try cleaning the battery terminals first, even if they look clean. Then you might try an APPS reset.
