A transmission lift arm to facilitate the safe lifting and/or lowering of a transmission from or into a transmission jack. The transmission lift arm is provided in pairs and each is adapted for attachment to a transmission bell housing utilizing threaded rods secured thereto. The lift arms may be adjustably spaced apart on the lift arm of a lift truck to accommodate various spacings is the bell housing holes into which the threaded rods are placed and secured. The transmission arms may also be provided in a variety of sizes to mount to different lift bar sizes and/or to have different size threaded rods to accommodate a wide range of motor vehicle transmissions. In alternate embodiments, transmission lift arms having an adjustable opening may be used to accommodate different lift bar dimensions.

1. A U-shaped transmission lift arm assembly, comprising: a) a substantially rectangular, thin spine having an inward facing major surface and an opposing outward facing major surface;b) a first flat, substantially rectangular elongated leg disposed substantially normally to and affixed to said inward facing surface of said thin spine;c) a first triangular brace having a right angle with a short side having a first end adjacent said right angle and a long side normal thereto and having a first end adjacent said right angle, said short side being attached to said inward facing surface of said thin spine parallel to a major axis thereof with a second end of said short side disposed adjacent a first end of said thin spine, said long side being attached to an upper surface of said first flat, substantially rectangular elongated leg parallel to a major axis thereof, said long side being shorter than a length of said first flat, substantially rectangular elongated leg;d) a second flat, substantially rectangular elongated leg disposed substantially normally to and also affixed to said inward facing surface of said thin spine;e) a second triangular brace having a right angle with a short side having a first end adjacent said right angle and a long side normal thereto and having a first end adjacent said right angle, said short side being attached to said inward facing surface of said thin spine parallel a major axis thereof with a second end of said short side disposed adjacent a second end of said thin spine, said long side being attached to an lower surface of said second flat, substantially rectangular elongated leg parallel to a major axis thereof, said long side being shorter than a length of said second flat, substantially rectangular elongated leg; andf) rods attached to respective top and bottom surface of said first flat, substantially rectangular elongated leg and said second flat, substantially rectangular elongated leg, respectively, said rods being disposed substantially parallel to a respective major axis of said first and said second flat, substantially rectangular elongated leg, distal ends of said rods projecting beyond respective ends of said first and said second flat, substantially rectangular elongated legs opposite said thin spine; anda lower surface of said first flat, substantially rectangular elongated leg and an upper surface of said second flat, substantially rectangular elongated leg defining an opening sized to receive a lift arm therein. 2. The U-shaped transmission lift arm assembly as recited in claim 1, wherein at least one member selected from the group: said first flat, substantially rectangular elongated leg, said second flat, substantially rectangular leg, said first triangular brace, said second triangular brace said thin spine, and said rods is formed from steel. 3. The U-shaped transmission lift arm assembly as recited in claim 1, wherein at least one member selected from the group: said first flat, substantially rectangular elongated leg, said second flat, substantially rectangular leg, said first triangular brace, said second triangular brace said thin spine, and said rods is connected to at least one adjacent member selected from the group: said first flat, substantially rectangular elongated leg, said second flat, substantially rectangular leg, said first triangular brace, said second triangular brace said thin spine, and said rods by welding. 4. The U-shaped transmission lift arm assembly as recited in claim 1, wherein rods comprise threads formed on an exterior thereof adjacent said proximal ends thereof. 5. An adjustable transmission lift arm assembly, comprising: a) a first leg component assembly, comprising:i) a flat, substantially rectangular elongated member;ii) a substantially flat vertical member having a rectangular portion contiguous with a triangular portion, said substantially flat vertical member being affixed an upper surface said flat, substantially rectangular elongated member along a midline of parallel to a major axis thereof, said substantially flat member being aligned with said flat, substantially rectangular elongated member such that a major axis of said rectangular portion is disposed substantially perpendicular to a major axis of said substantially rectangular elongated member, a lower edge of said triangular portion being aligned with an upper surface of said flat, substantially rectangular elongated member;iii) a pair of spaced apart through holes disposed proximate an upper edge of said rectangular portion of said substantially flat vertical member;b) a second leg component, said second leg component being formed as a mirror image of said first leg components but otherwise being identical thereto;c) a pair of connecting bars, each having a proximal end and a distal end, each having a pair of spaced apart holes disposed along a major axis of each of said pair of connecting bars and proximate said proximal end, and a central slot extending along said major axis, said slot beginning at a point proximate a lower one of said pair of spaced apart holes and continuing along said major axis to a point proximate said distal end of each of said pair of connecting bars;wherein said pair of spaced apart holes in each of said pair of connecting bars is sized and configured to align with said spaced apart holes in each of said first leg assembly and said second leg assembly. 6. The adjustable transmission lift arm assembly as recited in claim 5, wherein said spaced apart holes of a first of said pair of connecting bars is connected to said first leg component assembly and said slot of a second one of said pair of connecting bars is connected to an opposite said of said first leg component assembly, and slot of said first of said pair of connecting bars is connected to said second leg component assembly and said spaced apart holes of said second one of said pair of connecting bars is connected to an opposite side of said second leg component assembly. 7. A method of raising and lowering a component having a bell housing having through holes in an edge thereof, the steps comprising: a) providing a pair of transmission lift arm assemblies as recited in claim 1;b) placing each of said transmission lift arm assemblies on a lift bar of a lift truck at a predetermined spacing one from another;c) maneuvering said lift truck so as to align threaded rods forming a portion of each of said lift arm assemblies with through holes in said bell housing of said component;d) sliding distal ends of said threaded rods through respective ones of said through holes; ande) securing said bell housing to said pair of transmission lift arms by mating a fastener at said distal ends of said threaded rods. 8. The method of raising and lowering a component having a bell housing having through holes in an edge thereof as recited in claim 7, wherein said providing step (a) comprises selecting a pair of transmission lift arms having a spacing compatible with a height of said lift arm of said lift truck. 9. The method of raising and lowering a component having a bell housing having through holes in an edge thereof as recited in claim 7, wherein said providing step (a) comprises providing a pair of adjustable transmission lift arms and adjusting the spacing of said adjustable transmission lift arms to be compatible with a height of said lift arm of said lift truck. 10. The method of raising and lowering a component having a bell housing having through holes in an edge thereof as recited in claim 7, wherein said securing step (e) comprises mating at least one selected from the group: a nut, and a washer to said distal ends of said threaded rods.
