Mechanic's tip
Some solenoids are accessible by dropping the transmission pan (external); others are buried inside the valve body and require more disassembly. Always change the transmission fluid and filter while the pan is off — it's included labor. If multiple solenoids are failing on a high-mileage transmission, a complete solenoid pack replacement is often more cost-effective than replacing them one at a time.
