I did the turkey baster draw while running until it whined, and then just refilled with PS fluid as reg. maint. Now, that I recall that was like 6 or 8 months ago and have not noticed the jerk-over since.
I heard a rumor once PSF is just ATF without the dye. But, nothing's that simple.
Finally, I read where one of the regulars here actually rebuilt his pump and fixed it that way.
