The venting system has passages that run through the pump . It is critical that the pump cover and pump body have flat surfaces with no burrs . The bolts need to be torqued to specs . Also some aftermarket trans recalibrations run too much line pressure , and that could cause cross channel leaks into the venting system . Probably best to relocate the vent to the back of the case , and plug the bellhousing vent . If that's not possible , add a hose on to the vent tube and run that down to a catch bottle .
