Built for 2014-2020 GM applications, the ACDelco 85585333 restores the designed temperature control inside the transmission circuit. A stuck valve can keep fluid too cold, which slows shifts, or send it to the cooler too late, which lets heat build up. With the valve working, fluid stays in its ideal range, shifts stay smooth, and the transmission lasts longer.
