:ch is being set in "OFF position. (D, shift is inhibited.) '2: oil pressure is applied to both 2nd "apply" side and 3rd "releasen side of band servo piston. However, brake band does not contract because oil pressure area on the "releasen side is greater than that on the "apply" side. '3: Oil pressure is applied to 4th "apply" side in condition '2 above, and brake band contracts. '4: A/T will not shift to 4th when overdrive control switch is set in "OFF position.
