What would cause my Trans to start whining is coming from bell housing tq converter pump area fluid is full just changed it and filters trying to fix it but that didn't help any thoughts or suggestion? Trans shifts fine no powa loss or anything just this annoying whining noise truck is an 02 lb7 stock Trans

I had a problem like this with mine after they build it from a core it was in the rear of the trans and was the planetary gear. It sound like straight cut gears. So they just rebuild my core and put it back in my truck.

Any input guys? Is it maybe the converter? I crawled under the truck again and it really sounds like the noise is from the converter I just want to be sure befor I pull the Trans down. I don't want to pull it put the new converter in and have the noise still be there any help on this matter would be great
