Yes, the stator. My British dream cars don't have a stator, because in the '30-'50's
"Voith" I think they are good. At least they lasted on the buses. "ZF" also makes automatic gearboxes. Oh, the Romanian "Rocar" with "de Simon" type body also used "Voith" gearboxes.
On the interior on the "D.A.F." buses was and advert for "Voith" on which was among other image of a truck. I don't think in Romanian back in those days where trucks with automatic geraboxes, so I was in state of wondering.
