<p>A manually-shifted synchronized compound transmission (10) is provided with a relatively simple and inexpensive mechanism for warning the operator that an inappropriate gear ratio has been selected. Sensors (110, 112, 114) provide input signals (116) to a logic unit (118) indicative of the rotational speed of the transmission input shaft (118) and the logic unit will issue command signals (120) to an alarm member (122) if sensed input shaft speed is not within an acceptable range to warn the vehicle operator that reengagement of the vehicle master clutch (C) in the currently engaged ratio (GR) will result in undesirable overspeeding and/or underspeeding of the vehicle engine (E).</p> |
