ABSTRACT:
A method and system for hybrid automated manual transmission and non-hybrid automated manual transmission shift methodologies for tanker trucks are disclosed. A request is received to change a transmission gear ratio of a vehicle transporting a liquid. The request is rejected if a condition indicative of liquid sloshing is detected, and the gear ratio is changed from a current gear ratio to a target gear ratio if the condition indicative of liquid sloshing is not detected. A trigger may enable the detection of liquid sloshing. A transmission controller selects a current gear ratio of the transmission, detects a condition indicative of sloshing of the liquid transported by the vehicle, disables a selection of a select a target gear ratio of the transmission if the condition indicative of liquid sloshing is detected, and selects a target gear ratio of the transmission if the condition indicative of liquid sloshing is not detected.
