Installing a lockup switch (mystery switch), is not bad, using it can be... If used wisely it won't cause any problems. If you shift locked between 2 and 3rd, well that will shock the drive train pretty hard. Forgetting to unlock the convertor when coming to a stop is also not a good idea. If I were you, I would put some miles on your new transmission and then decide if you want to put in a mystery switch. With a 91% convertor, I think you will find you really don't need a mystery switch. At the drag strip you will see lower E. T. 's, especially with a 99, because if I remember right it doesn't shift locked from 3rd to 4th at WOT. I'm sure someone will correct me on the 99 if I'm wrong.

If you can shift locked to locked all the way into 4th then your are more efficient in getting your power to the ground. Your transmission should be able to handle it.
