Make darn sure the convertor is in all the way. The face of the TC has to be inside the bellhouse. When that is done, rotate the TC about 20* one way and then change directions I usually can hear the pump drive slamming the pump with a satisfying cluck every time it changes directions.
Thanks, I did check and the face is certainly behind the plane of the bellhouse. I can definitely feel it engaging the pump when I rotate it back and forth.
Any sort of final to-dos or a good checklist before dropping in the motor?
