904 / New Converter, abnormal noise

no, the trans is not a lock up unit, 4028464 from 76/77. The new custom made converter is also not a lock up unit…..at least i did definitively not order a lock up unit.

The converter stator splines inner diameter is much bigger compared to a stock converter, even bigger than the inner Diameter of the converter hub. I think i found the Problem, gonna tell the manufacturer about it. I´m not amused.

Will keep you updated.
