How do you mean conversion. Is there a new controller, or you talking about the switches that let you lock the tq converter and chose which gear your in on the auto. If it is the second, I installed mine in 2002, love it. Wife can't figure it out, so it is a his/her switch in my vehicle. The tcu will learn your driving. If you rev it out then switch gears, when you controll it, when swithced back, the tcu will do the same. And if you flip thru the gears, the tcu will do the same. It will reset it's self when you turn the key off, so it wont freak out the other drivers (if your married like me and she likes to drive it)
