Technology & Maintenance Council


The purpose of the Technology & Maintenance Council is to improve transport equipment, its maintenance and maintenance management. The Council develops Recommended Engineering and Maintenance Practices that are voluntarily adopted by fleets, OEMs and components suppliers.

The Council also conducts industry surveys and promotes the voluntary cooperation among designers and manufacturers of transport equipment and those who specify, purchase and manage such equipment.

Who We Support

The Technology and Maintenance Council supports the ATA technology & Engineering Policy Committee with research, analysis and policy development.

TMC IR 2015-3, Exploring the Potential for 48-Volt Commercial Vehicle Electrical Systems

Forty-eight volt electrical systems represent a great potential to save fuel and reduce greenhouse gas emissions. Idle stop-start technology can help save fuel while the vehicle is motionless, and torque assist can also be supplied to the engine for launch and low-speed momentary acceleration. Increased energy storage and recapture of brake energy is also possible through 48-volt electrical/electronic (E/E) technology, further improving on overall efficiency. In addition, there are other possibilities with the use of a 48-volt supply that would not be possible with a 12-volt battery in in a commercial motor vehicle (CMV), such as electronically controlled air-conditioning (A/C) compressors and fully electric power steering.

Future Truck Position Paper 2019-3: Recommendations Regarding Future Commercial Vehicle Braking Systems

New requirements for reduced stopping distance (RSD) and stability are prompting manufacturers to consider emerging technologies in order reduce response time in heavy-duty commercial braking systems, thereby improving overall vehicle safety and efficiency. TMC recommends accelerating research and development of future braking systems to overcome limitations of current pneumatic braking system designs, leverage emerging technologies in conjunction with those currently available in the marketplace. This position paper discusses the opportunities and potential limitations that need be addressed and provides a baseline from which research projects can be developed.

Future Truck Position Paper: 2019-2, Future Driver Accommodations: Equipment User Expectations for Driver Seating and Controls Packaging

Having studied issues with driver seating and control packages for all known driver population profiles — especially ones of smaller stature — TMC’s Future Cab & Driver Interface Task Force proposes in this paper that equipment manufacturers and suppliers develop “adjustable pedals” to accommodate the full range of drivers. Just as adjustable steering columns were necessary to accommodate larger stature drivers (especially ones with a large girth or long legs and shorter arms) and longer seat tracks were necessary to accommodate the long and short leg extremes of the driver population, the time has come to address the pedal issue.

Average Standard Repair Times (SRT) for 75 Commonly Performed Labor Tasks in Fleet and Service Provider Operations

ABSTRACT Fifty-four TMC member fleet and service provider members responded to TMC’s “Fleet & Service Provider Average Standard Repair Times Survey,” which was administered in the first quarter of 2019. The purpose of the study was to aid in establishing baseline repair times that will improve shop productivity and profitability. The survey was based on Vehicle Maintenance Reporting Standards (VMRS) making it easier to aggregate repair times. Participants were asked to provide the time in hours to install specific parts or to perform needed labor in their facilities, not the rates that participants necessarily charge their customers. Data presented in this report is based on the labor description and the corresponding VMRS Code Keys for each task using VMRS Code Keys 15 (Work Accomplished) and 33 (Component Code). Repair and replacement of clutch assemblies and automatic transmissions were reported to be the most labor intensive tasks, followed by EGR cooler and radiator removal and replacement. Of the 10 most labor intensive tasks, three were associated with emission/exhaust, and two with engine/coolant systems. Conversely, four of the least labor intensive tasks were associated with brake system related repair/replacement.

TMC IR 2018-1 Determining Technician Entry-Level Skills

This information report presents the results of the Professional Technical Development Committee’s (PTDC) Task Force on Determining Necessary Entry Level Technician Skills. The charge of this Task Force was to examine means of determining these essential skill sets to become a qualified applicant for technician positions in the industry. This report discusses the activities of the Task Force and resulting changes made to requirements for accredited technical training through the National Institute for Automotive Service Excellence (ASE) and its National Automotive Technician Education Foundation (NATEF).
