Watch the video. What’s that sound? Only at idle. Only in sport mode.

Preface: love my ST. This is rare. If you’re reading this and looking to buy an ST then please do not consider this a complaint. I note that I don’t know of anyone else with this issue.

Hi guys and gals, I want to bring this to the attention of our tech savvy members who like a challenge. Watch the video and tell me what this sounds like?

- video is me toggling between normal and sport mode
- noise occurs at start up (no warm up required)
- only in sport mode
- only when idling (cannot hear it at speed)
- cannot hear it from inside vehicle
- becomes extremely loud (embarrassing) after vehicle is warmed up
- most prominent on passenger side under footwell


If swapping modes is software based, what might be actuating to cause this heinous ratcheting/rattling? Thanks in advance.

- Bruce

Sounds metallic. I would have to say the flex pipe rattle?

Originally we thought the same. However that rattle was taken care of (twice actually). But why in sport mode?

I can't find the thread (still looking) but you aren't the first person with this issue. When 10R60 transmissions go into "sport mode" it changes the oil pressure circuit--i imagine that part beginning to yolo itself is your issue. remedy has always been a new valve body.

I will look but if you come across it please post it here. Much appreciated!
