My generation Focus has a transmission that is known to be a little "whiney". The transmission shifts perfectly, so no problems there. I'm just curious if any transmission additives would help quiet it down?

^Another vote for Lubegard Red here. Adding 1 pint shouldn't overfill, just make sure it isn't over already. wink

May take around 500 miles to fully show any type of improvement. Good luck.
