Any way to control torque converter lockup?

I modded an auto trans to act like a certain irl shift kit that will hold gears lock the converter etc. Ive figured out the holding gears/a semi auto but was wondering if I could lock the converter with a button like real life?

 

Thanks for the help, just had to make a folder in that mod for the vehicle I wanted and its exactly what I was looking for.

 

How did you put that mod into your desired vehicle folder? I am trying to make it work with a mod vehicle.
