fresh 727 problem

Used a rubber tipped air blower to test the front and rear clutch drums,the rear clutches locked up nice but the front clutch would not lock up and air seemed to be leaking around the pump area but anyways guess she's got to come back out ,,, reverse and 3rd are on the front clutch pack right just checking , and could a worn bushings cause the leak , I remember testing before I put in the first time and it would lock up but seemed a little funny but I had nothing to compare it to
