Hi I just wondered if anyone know what was causing my whine problem in park and neutral. If you just start up the car cold it's fine it goes through all gears fine normal cruising and hard floor smashing but if you put it in neutral or park after being driven it will whine. It desn't seem to affect the performance of the transmission just an annoying and embarrasing whine when you put it back in park. If you wait a while after you've shut the car off and let it cool for an hour or more you can start it up and there's no whine. Tried replacing the valve body and seperator plate and checked the passages on the other side of seperator plate for buildup and didn't see anything. any ideas?
