I got a whinning noise coming from my transmission, It is coming from the front. It sounds almost like a noisy gear drive. I took the cover off the torque converter and see nothing. It only does it in gear not in park or neutral. The tranny still shifts fine. It is not the starter. What could this be?
I get a whining noise from my passenger seat sometimes....that's why I leave her at home a lot!
But seriously....
I think the pump can cause a whine under pressure. Did you do a search? I'm sure I've seen this covered before.
Maybe the filter is clogging up ??--I had a "whiny" TH400, when the fliud and filter was so dirty it clogged the filter up--noise went away after I changed both..but it was noisy in park and neutral, as well as in gear..
Usually the front pump is the source of whining noises,could be yours is going out..also ,cavitation(air in the fliud), can cause the fluid to foam up, and air trapped in the pump can cause whining noises..overfilling it can cause cavitation..water in the tranny fluid can cause this too..
What could this be?
