PURPOSE:To make an automatic axle transmission small-sized by exciding a part of the outer periphery of a pump body to let a final drive pinion enter, and disposing an intake port near the excided portion and arranging a discharge port and necessary oil holes apart therefrom. CONSTITUTION:A part of the outer periphery of a pump body is excided, and a final drive pinion 10 is let enter the excided portion 18a. An intake port 20 is disposed near the excided portion 18a, and a torque converter release oil hole 22, a torque converter apply oil hole 23, a high-clutch pressure oil hole and a reverse clutch pressure oil hole 25 are disposed apart from the excided portion 18a. Thus, the distance between shafts of an oil pump and the final drive pinion is reduced to make an automatic transmission axle small- sized, and a raised portion produced by the oil holes is not produced in the intake port so as to prevent lowering of a pump performance. A raised portion 26 is produced in the discharge port 21 so as to reinforce the discharge port portion. |
