Abstract
A diagnostic system and method for diagnosing problems in a hydrostatic transmission of a vehicle including a transmission control unit that has a monitor and pressure sensors and at least one temperature sensor connectable between diagnostic hose ports coupled to the transmission and inputs on the transmission control unit. A symptom or problem area is selected on the monitor; and a test sequence is initiated by command input on the monitor. The transmission control unit performs calculations based upon input data from the pressure sensors to determine a hydraulic problem, and provides directions for adjustments or replacing parts on the hydrostatic transmission. The monitor may provide instructions to relocate existing sensor connections for the test sequence selected.
