15. NOTE: Solenoids and clutch control valves may visually appear the same but they are calibrated from the factory and are not all the same. Use care not to assemble the main control assembly incorrectly. Incorrect solenoid and clutch control valve installation results in poor transmission shift quality.

    Number the solenoids 1 through 6 and number the main control solenoid ports 1 through 6 to correspond to the solenoids.
