  • Patent number: 5975480
    Abstract: A motor mount for a motor having an elongate drive shaft. The motor mount includes a base having a generally planar surface. At least one elongate rail is disposed at the surface of the base. A motor carriage plate has a generally planar bottom surface disposed approximate to and generally parallel to the surface of the base. The motor carriage plate has at least one rail engaging surface disposed at an angle to the bottom surface. The motor mount includes a motor carriage fastener for fastening the motor to the motor carriage plate. A fastener is provided for attaching the motor carriage plate to the base plate such that the rail engaging surface engages the elongate rail.

  • Patent number: 5803869
    Abstract: A powertrain for a vehicle includes an engine, a multi-speed transmission and control, and output drive mechanisms. The transmission has an electro-hydraulic control for establishing the transmission drive ratios and the interchange therebetween. The ratios are established by a plurality of friction devices, one of which is engaged for the lowest forward ratio. The control has a microcomputer which evaluates vehicle operating parameters and maintains the transmission properly controlled in response to various input signals. The transmission is maintained in an auto neutral condition when the engine is at idle, the transmission output speed is zero, the vehicle brakes are engaged and the forward drive has been selected. The control continually adjusts the pressure in the one friction device to maintain the torque capacity thereof in a range less than full engagement and greater than a minimum value.
