An improved control system for a change speed multiple drive axle assembly, such as a tandem axle assembly (10), having a lockable interaxle differential (35) is provided. The improved control system (306) permits engagement and disengagement of the interaxle differential lockup in either the high or low speed ranges of the tandem axle mechanisms (11 and 12) and includes means to sense actual and/or impending engagement (96) of the interaxle differential lockup (84) to prevent operator shifting of the axle shift selector switch (150).
