Abstract:
1. An automatic transmission comprising: a torque convener comprising a pump impeller, a turbine runner, and a stator; a transmission input shaft to which the turbine runner is attached; a transmission mechanism that changes a transmission ratio to change input torque and input speed transmitted to the transmission input shaft; a stator shaft that supports the stator on an outer periphery and rotatably supports the transmission input shaft on an inner periphery; a magnetostrictive torque sensor that detects a magnitude of the input torque transmitted to the transmission input shaft; the magnetostrictive torque sensor comprising: a torque-sensor retaining sleeve fitted to the inner periphery of the stator shaft, wherein the torque-sensor retaining sleeve is configured to prevent axial motion of the magnetostrictive torque sensor relative to the stator shaft to retain the magnetostrictive torque sensor at a predetermined installation position.
