    Default Note

    The 4L60E 3-2 solenoid is not shift solenoid;

    the 4L60E HMTG calls it 3-2 control solenoid;

    it controls the 3rd accumulator fluid exit rate, so controlling the apply rate of the 2nd servo (which applies the band in 2nd gear);

    the 4L80E does not have this solenoid.

    this solenoid is specific to the 4L60E/4L65E/4L70E;

    it appears that GM has eliminated it in some of the later 4L65E/4L70E models.
