The automatic transaxle on the Accord and Prelude provides for the transmission of engine torque and power to the front wheels over a narrow range of engine operating speed, thus ensuring that at low speed the engine can deliver plenty of power and torque while at high vehicle speeds, a reasonable rpm is eminently maintainable without any input from the driver. It employs a light fluid as the means of transferring power and also as the operating fluid for hydraulic control circuits and as a lubricant. Having multiple roles, a mechanic of the transaxle fluid means that a problem within the unit can quickly transfer between a number of components. Thus, evident widespread of the transaxle units combined with their peculiarities could not leave aside the impact on the idea that, while diagnosed, the underlying knowledge of the unit's fundamental principles of operation is the leading prerequisite for their successful troubleshooting.
