Abstract: A transmission fill gauge system for a vehicle transmission includes a fill gauge assembly and a vacuum adapter assembly, wherein the vacuum adapter assembly and the fill gauge assembly are configured to be simultaneously in fluid communication with a transmission drain pan of the vehicle transmission. A method of measuring a transmission fluid level in a drain pan includes fluidly connecting a vacuum adapter assembly between a fill port of the vehicle transmission and a constant vacuum source, applying an internal vacuum pressure to the drain pan via a constant vacuum source, removing a drain plug from a drain on the drain pan, attaching a fill gauge assembly to the drain, the fill gauge assembly having a primary fluid tube slidably mounted in an elongated body portion, sliding the primary fluid tube to a predetermined position, and discontinuing the internal vacuum pressure to the drain pan by closing the valve.

Abstract: A valve keeper verification tool is provided. The tool may include: an elongated body having two ends; an axial hole in one end of the body dimensioned to fit over a valve stem; and structure surrounding the hole dimensioned to contact at least one keeper of a retainer for an engine valve, wherein the tool is angled near the hole between about 10 and about 25 degrees. A method of checking to ensure a valve retaining keeper is in place may also be provided. The method may include: inserting a valve stem into a hole in a valve keeper verification tool; moving the valve keeper verification tool against a keeper; and applying a force against the keeper.

Abstract: A brake piston compressor is provided. The brake piston compressor includes: two blocks; a forcing screw configured to engage the blocks to selectively bring the blocks closer together or farther apart from each other depending upon which way the forcing screw is turned; two pads each pad configured to be slidably engaged with at least one block; and a locking mechanism configured to engage and disengage to lock one of the pads to one of the blocks when the locking mechanism is engaged. A method of operating a brake piston compressor is provided. The method includes: sliding a pad into a channel in a block; locking the pad to the block; and turning a forcing screw to move the pad and block with respect to a second pad and block.

Abstract: An apparatus and method are provided that allow a diagnostic tool to communicate with a data link connector in a vehicle and place the vehicle in a desired state for diagnostic testing. A cable that can automatically multiplex its connections in order to make the appropriate connections between the diagnostic tool and the data link connector based on a communication protocol of the vehicle under test. A connector allowing for selective switching of pins of the connector to jump connect the selected pins. This allows the vehicle to be placed in the proper state for diagnostic testing and the diagnostic tool to communicate with the data link connector regardless of the pins being used by the communication protocol of the vehicle.

Abstract: A method and apparatus for jumping a pin connections in an electrical device are provided. The electrical device can be a vehicle having a data link connector that once mated with the apparatus, such a jumping connector that will jump at least two pin connections in the data link connector. The jumping connector can also have dip switches that be in the active or inactive state. In the active state, the dip switch will cause a connection to one of the pin connectors on the electrical device while the inactive state, the dip switch will not cause a connection to one of the pin connectors on the electrical device.
