Yeah,
I built this unit some time ago and the customer was just getting ready to put it in the car and the converter wouldn't fit, so I had the customer take the trans and converter to a local shop to check the trans with a stock reman converter and check the converter with a stator or pump assy.
It was the stator shaft. Not burred or visibly damaged but just too large. (Not a problem I usually have :biggrin: )
