First of all, sorry to be here only when I need something...Life is so busy that I seem to just post a question about every 6 mos. Hopefully life will slow and I can socialize with you guys on this forum more often. So anyway, without discussion of the fabrication and physics of this task, will a PS gearbox work mounted upside down, just strictly from a hydraulic standpoint of view? I want to mount a Isuzu NPR ps box in a COE and it seems it will work if upside will distribute the fluid properly. When fabricated in place, the PS lines would screw UP into the BOTTOM of the unit when mounted as I need it to. As always, thank you guys for information. All my best. Tom
