Abstract:
A drive combination comprising:a torque converter to driveline coupler adpated to be driven by a torque converter and to drive a transmission, the torque converter to driveline coupler having a coupler shaft constructed to engage and be driven by the torque converter, and a fluid pump that engages and is driven by the torque converter when the torque converter engages the coupler shaft and that supplies fluid under pressure to the torque converter, and a countershaft transmission having a clutchless power path including a first gear mounted on a first shaft to rotate with the first shaft, a second gear and a third gear mounted on a second shaft so that the second gear and the third gear rotate with the second shaft, the second gear meshing with the first gear; and a fourth gear rotatably mounted to an output shaft and meshing with the third gear, the fourth gear selectively engaging of the output shaft by mechanical engagement to rotate together with the output shaft; and the coupler shaft operatively connected to the first shaft to cause the first shaft to rotate when thecoupler shaft rotates.
