I did a search and found a lot of info on various types of torque converters for the SC's AOD (locking vs non-locking, a wide range of stall speeds, etc). What I didn't find was specifications on the original stock TC that came with the SC AOD. I'm having a tranny built with the typical upgrades and the TC is the last piece of the puzzle. My SC is a "daily driver", never been on the track. I would like to find out about the stock unit so that I can determine if I should upgrade. My goal is to optimize the street performance without jeopardizing the driveability and efficiency. Sorry if this info is already posted somewhere, I didn't find it...
