If you install the switch, follow his guidelines for use. Then adapt them to how and where you drive such as mountain towing etc. " You should unlock your TC at speeds below about 25mph or RPMs below 1000 so as to avoid TC damage".
Also locked below 1000 rpm could cause engine stall. Not good to lose steering and brakes in traffic.
Some chips reprogram TCC lockup and unlock rpm. You can have them programmed for your needs.
