Designed to fit servo cover castings marked CA or CB with an inner diameter of 1.845\", this piston is an exact-fit replacement for OEM part number E2ZZ-7D021-CA and cross-references E3ZZ-7D021-A.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe servo piston controls band application for both the intermediate and overdrive clutch circuits. A worn or failed piston causes delayed shifts, slipping between gears, loss of 2nd gear or overdrive engagement, and in severe cases can render the transmission unable to hold a gear under load. Replacing this piston restores proper hydraulic pressure and firm, consistent band engagement.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis molded piston is sold individually and fits either the intermediate or overdrive servo position.
