A system of a work vehicle (10) includes an engine (12), a transmission (14) that includes a hydrostatic unit (48), and a clutch (44) coupled to the transmission (14). The system also includes a controller (42) communicatively coupled to the engine (12), the transmission (14), and the clutch (44). The controller (42), in operation, receives a command to disengage the clutch (44). The controller, in operation, determines an engine speed of the engine (12). The controller (42), in operation, also determines a temperature of hydraulic fluid in the clutch (44). The controller (44), in operation, further determines a magnitude and time to limit acceleration of the work vehicle (10) based on the engine speed and the temperature. The controller (42), in operation, also commands the clutch (44) to disengage. The controller (42), in operation, further limits the acceleration of the work vehicle (10) using the hydrostatic unit (48) based on the magnitude for the time determined.
