Hey guys. I have a FG25ST-16 with a horrible whine coming from the transmission. The lift does drive forward and reverse but at times seems to hesitate a little. I tried checking pressures but haven't found any info on what ports test what. The port on top in the middle of the trans case that takes an allen wrench shows a pressure of 150psi but fluctuates around 10psi. I tapped into the same style port by the trans filter and got no reading at all. I see a few other very small ports in the case but have no idea what at these show if anything.
Does anyone have any insight into this?
Thanks
