A Car Transmission Jack usually refers to a car jack that can be extended high enough to reach the transmission of a vehicle that has been lifted on a two-bar lift or four-bar lift. This style under the car jack allows the operator to stand under the car while disassembling or installing the transmission. The other is a small transmission jack for removing or installing a transmission without supporting the vehicle on a car elevator above ground level.
Single-stage jacks and two-stage jacks can both raise to the same full height. The two-stage transmission jack can be lowered by its second stage, which is much lower than the minimum height of the single-stage transmission jack. When installed in the transmission jack, the lower position of the two-stage jack allows the operator to safely roll the transmission throughout the plant.
The lower height also allows the operator to easily move it from the transport jack's mounting platform to the workbench. The single-stage transmission jack will not allow it to be lowered to the ground furthest from the two-stage transmission jack and usually more than one person will be required to transfer the transmission from the jack to the workstation because the transmission is higher off-site.
Car transmission jacks use manually operated or pneumatically operated hydraulic pump systems. Most single-stage jacks have a hydraulic pump driven by a handle pump or foot pump. Foot pump operation on single-stage jacks is much more efficient than manual hydraulic pump levers. The foot switch allows the operator to lift the jack's mounting platform and still be able to move the platform head to the correct angle under the gearbox with both hands.
Most two-stage car transmission jacks use the first and second stages of the foot pedal jack. Technicians hold both hands free while lifting the transfer jack platform so both hands can be used to ensure that the platform is properly positioned underneath the drive during disassembly or installation. When installing the gearbox, the operator can help align the gearbox while lifting the gearbox in place.
