I searched all 15 pages of tranny noise , but none matched mine. After sitting for weeks I hear a loud clanging when the tranny is put in reverse. It sounded like a fan blade was hitting a cooler line, but that's not it. When shifted into drive the noise goes away. The car drives and shifts fine when warm and no noise when in reverse. I checked fluid level and that's ok.
Any ideas before it goes to the shop? Thanks guys.
