Wondering if anyone has run into this concern. I have a 2001 ram with a 46re trans that makes a bearing type noise in 3rd and 4rth gear only. The noise sounds like a bad bearing (whine) or a planetary gear failing. The tone of the whine will change speeds when the trans shifts between 3rd and 4rth. The problem is I have the trans completely disassembled and I can not find anything wrong. All the bearings and planetary gears feel fine. There was no metal in trans pan either.
Thanks in advance for any ideas.
