    4. NOTE: Solenoids are calibrated from the factory and are not all the same. To replace a solenoid, match the replacement solenoid type (normally high/normally low) and the band number with the original solenoid or harsh/erratic shifts, harsh/soft engagement or damage to the transmission can occur.
