Howdy

I'm having an issue just now, I was sent a non-lockup torque converter for my 700R4 and it slips unless I'm on the throttle hard. It took no less than four calls to Summit's tech line before I was able to fugue out the right questions to ask to rectify the issue. In hindsight, it is pretty simple. Just needed a lockup with smaller stall.

My question is, what is the application for a non lockup converter?
