Helps make your BMXA transmission shift like new.
ONLY USE OEM NEW, never buy out the junkyard.
Reason is, these solenoids wear out after 20 years, but dont throw a code. Then the clutch material in the oil blocks up the passages needed for the valve to work. Then the clutches get worn out quicker, put more clutch material in the oil, worsening the cycle until the internal filter clogs and blocks oul flow, then the trans doesnt work.
This is why you dont buy used solenoids, they already sont work well.
