Default TC lock up question?

What are the thought on locking up the TC at higher speeds as at 95mph? Should it be locked or unlocked for better performance? I am running a SY3500.

If you're cruising on the highway at 95 under light throttle, it should be locked. Your fuel mileage will be bad if you're driving at 95 with it unlocked. Of course if you dip your foot into it, the converter should unlock and you start pulling pretty good.

Are you actually having lockup problems, or just inquiring?

I'd set it to stay locked at under 50% TPS. Above that you probably want it to unlock for bettter performance.
