Introduction
The advancements in automotive technology have introduced solutions to the indispensability of vehicles in the business world (Piromalis&Kantaros, 2022).As the number of vehicles on the road increases, there is a growing demand for more efficient and safer operational designs, albeit at an increased cost due to the integration of new features.Preventive maintenance is imperative for optimal performance and safe driving, especially in the case of manual transmission vehicles.A vehicle's drivetrain comprises numerous moving parts and components that necessitate regular service and maintenance to prevent major issues and extend the vehicle's lifespan (Bhatti et al., 2021).Inadequate maintenance can lead to the breakdown of various parts over time, as wear and tear affect any moving component.Replacement of clutch elements like the clutch disc, pressure plates, and bearings often involves the disassembly of the vehicle's transmission assembly (Tushar et al., 2020).Automotive mechanics frequently encounter challenges when it comes to disassembling transmissions due to a lack of suitable tools or equipment capable of safely holding, raising, and lowering the transmission assembly (SattarpanahKarganroudi et al., 2022).This need drove the researcher to design and fabricate an appropriate apparatus to aid in the handling, lifting, and lowering of transmission assemblies during servicing.An example of an existing invention is Julian Garate's transmission jack (1975), which facilitates the lifting and placement of automotive transmissions under a vehicle and their removal for replacement or repairs.However, it relies on a wide base for stability and support, limiting its flexibility.George V. Johnsen's transmission jack (1954) depends on an array of adapter plates specifically designed for various transmission sizes and makes.The overall height is restricted in this design, and it has limited lifting capacity.Shelby J. West's transmission jack (1993) enhances safety and maneuverability but still has limitations.The Transmission Lifter is a specialized tool designed for securely holding a transmission during removal from the engine.However, the existing designs and features differ from the practical requirements of most mechanics in the industry.The aim is to create a Transmission Lifter with versatile features and functions that can adapt to a wide range of tasks and scenarios, whether the vehicle is elevated or not.This invention has been conceived to fulfill this need effectively.

Significance of the Technology
The Transmission Lifter assumes a crucial role in the extraction of transmission assemblies, particularly in automotive service establishments.It serves as a linchpin due to its ability to simplify, expedite, and enhance the safety of this task.When wielded with appropriate ergonomics and skill, this device enables mechanics to execute their duties with reduced stress and enhanced comfort.Within the realm of the automotive industry, clutch and transmission repair procedures necessitate distinct methods and specialized tools to address challenges encountered during transmission removal from the engine.The creation of the Transmission Lifter proves to be a suitable and advantageous addition to any automotive repair shop.This innovation not only guarantees quality service but also promotes the safety of automotive mechanics.
The adoption of innovative equipment like the Transmission Lifter by automotive mechanics not only saves time and effort but also ensures the safety of everyone within the workplace.Acknowledgment of the Transmission Lifter by the industry instills confidence in vehicle owners seeking clutch and transmission services at various automotive repair facilities.Mechanics can deliver high-quality work by utilizing user-friendly equipment such as the Transmission Lifter, thereby ensuring safety.Service shop proprietors gain confidence in offering superior customer service by employing safe and suitable tools for their services.This operational efficiency results in increased revenue as a single mechanic can perform tasks efficiently and is duly compensated for a job well done.Ultimately, the development of equipment or machinery in the automotive sector serves as an inspiration for students and other researchers to pursue further innovation in the form of machines or tools that prioritize user safety and comfort.Future research and innovations are poised to find ready acceptance among users within the industry.

Design Criteria
The design of the Transmission Lifter adhered to established specifications in accordance with the Mechanical Engineering Handbook, the Philippines Society of Mechanical Engineers Code, and Manufacturers Standards.The Transmission Lifter design encompasses the following key elements: Steel Plate: A steel plate, 2.3mm thick, 14 inches wide, and 1 1/2 feet long, serves as the platform on the lifter ramp, designed to securely cradle the transmission assembly.This platform forms the basis for the Transmission Dolly's mechanical system.Pneumatic Cylinder: The pneumatic cylinder acts as a linear actuator, powered by compressed air to exert force on a load.Metal Wire Spring: This elastic object stores mechanical energy and is typically crafted from spring steel.It functions to provide opposing force when compressed or stretched from its resting position, with the force approximately proportional to its change in length.The spring has a stiffness of 10 N/mm and a compliance of 0.1 mm/N.When springs are in parallel, their stiffness (or rate) is additive, just as the compliance of springs in series.Steel Shafting: A rotating machine element, usually circular in cross-section, utilized to transfer power from one component to another.In the design, a 3/4-inch thick, 36-inch long steel shafting is used to facilitate both the upward pulling and the downward pushing of the upper assembly, securely holding the transmission in place.Angle Bar: An angle bar with a dimension of 6.4 mm in thickness and 1 1/2 inches in width functions as a frame member in the Transmission Lifter design, offering structural support for the platform.This angled frame supports the elevation and lifting of various types of transmissions.
