A converter allows a user to convert a conventional car jack from a non-specialized, general service variety into a specialty transmission jack. The car jack has a low, wheeled frame; a handle; a boom extending between a base end pivoted to the frame near the handle and an opposite end formed with a seat portion; and a hydraulic cylinder stretching between the frame and the boom which is actuated by pumping the jack handle to raise the boom. The seat portion of the boom is formed with a socket. The car jack conventionally is provided with a conventional cup having a stem which allows removable seating in the socket of the jack's boom. The converter head has a base plate defining a plane; a stem beneath the base plate for removable seating in the socket of the jack's boom; four or so arms extending between a butt end and a tip end; and cap screws threaded through the tip end of each arm. The cap screws allow adjustment in length and provide upper contact ends for propping a vehicle transmission thereon. The arms have slots in them and are bolted to the base plate by these slots such that the tip ends can be adjustably moved and locked into located in various positions substantially in the plane of the base plate. Wherein swapping back and forth between the cup and the converter head allows conversion of the jack into the specialty transmission jack.

A wheel lift device includes an upright extending upwardly from a wheeled base. A carriage slides along the upright and includes a wheel support to support an automotive wheel thereon.
