Re: Turbo 350 or 400 trans cooler lines
Some Powerglides have a one way bypass valve inside the pump. If for some reason the cooler got plugged the bypass would allow oil to flow and keep the oil flowing through the converter and lube circuit . It would still overheat the trans but save the "hard parts" . For racing it would still be better to loop the cooler fittings , which would give more flow.
