Is not stock due to it's stall speed. It may be a stock modified converter. Please refer to this post link below as I myself is trying to decode exactly what converter this is. I know it works, stalls at 2500rpm on the foot brake and I have seen 2800rpm flashes. I have estimated it to have 2500-3000miles.
Appears to be a re-stalled D5 converter. Bottom line - it will flash 2800rpm/foot brake 2500rpm; ran the best of a 1.7 60ft and 11.86s with this converter and it only looses 700rpm between shifts.
