A heads up. When going with lock up. Go with the lowest stall you need as any higher will kill its unlocked effiecency.
I.e. the car will be slower unlocked in 3rd
A non lock up convertor "hydraulical coupling wise" be the best in comparison to a L/U UNlocked.
Now a L/U LOCKED at WOT will be better but much harder on the trans and need to have all the strong stuff in it.
