Non Lockup To Lockup

Well, after thinkin on it, I don't think it would gain me anything, would it? My three speed is 1:1 in high gear. Isn't that ALL a lockup does? Give you true 1:1 when the converter locks up? If that's it, I'm there already.
Zackly! A lot of work for no gain. Unless your left knee don't like cluthin' no more!
