ACDelco Automatic Transmission Valve Body Check Ball

The ACDelco Automatic Transmission Valve Body Check Ball is a replacement valve body check ball for automatic transmissions. Check balls sit in the valve body's fluid passages. They seal or open hydraulic circuits so that fluid pressure is directed correctly during shifts. A worn, damaged, or missing check ball can cause harsh or delayed shifts, slipping, or loss of pressure. Replacing it helps restore proper shift control.
