No lock on the converter, it is custom made by Precison of New Hampton IA with no converter clutch. The trans I am running has no TCU so im not sure if you would even be able to lock the converter if it had one.
You can lock most of them with a switch (though there are better ways of course...usually some kind of solenoid in the VB that engages the lockup).
Interesting to hear about your setup though, thanks for sharing. Might have to contact them to see if they can build a TC with a lockup strong enough to take power. I mean I have a 6spd and don't really plan on changing that - just curious. Thanks,
