i have a bagged 87 chevy that lays hard, the problem i am faced with is the slip yoke on the 700r4 tranny. Does anyone know if they r common to piss fluid out of the tranny tail or is it possible the meaurements r off and the rear end is pulling the slip out too far, im no genius to the air bag world but has anyone encountered this or know of a cure.  all help and input would be gratelly appreciated..
