My transmission whines. When the engine starts and the trans is in park, the whiny noise is quite loud. When I put the trans in gear, the whine quiets down, but I can still hear it. When the trans winds up the whine gets louder until the trans shifts to a higher gear. The shifting works fine. The car drives fine. It just whines.
This it has always been a bit whiny, but it got worst after I had the fluid changed (but not the filter) at an oil change place. The noise has been happening for several months, and now the check engine light is on and the code is one about the Torque Converter (CODE PO741 - TORQUE CONVERTER CLUTCH SYSTEM STUCK OFF).
Is this a contaminated valve problem? The oil is very clean now.
