What is the best strategy for shifting the A4LD into 4th (OD) and converter lockup? Is the ability to lockup in 3rd (1:1 ratio) important in a car with lots of horsepower? I'm thinking of combining switches so that the trans would lock up only as it was shifted into 4th. 3rd (1:1 would only be available with an unlocked converter. Or to put it another way, OD (1:.75) would only be available with a locked up converter. Bad idea?
