I put Celica PS on my samurai and am not getting any preformance from it. The pump doesn't make any noise like it is cavitating, I turn the wheels back and forth with the front off the ground and the fluid levels change in the reservior with no bubbles. I have tried bleeding it from the discharge side of the box. I ran PS fluid in it then switched to ATF and it seems to be a little worse. Any input would be appreciated.
