Lockup switch?

[Newstroker]

I have been seeing people talk about a TC lockup switch for these trucks but then other people say it cannot be done. So, I am wondering if a TC lockup switch can be installed or not. I am mainly looking to use it for sled pulling to make sure the TC locks. Any input would be great. If it can be done, does anyone have a how to.

Just have your Tuner make you a Custom tune for sled pulling that locks up the converter.
