• TMC Releases Updated Troubleshooting Ride Complaints Manual

    ATA’s Technology & Maintenance Council (TMC) has released an updated version of its Troubleshooting Ride Complaints manual.  The newly revised manual features 100-pages of information on how to identify, evaluate and troubleshoot ride complaints. 

    TMC’s Troubleshooting Ride Complaints manual is based on TMC Recommended Practice 648A, Troubleshooting Ride Complaints, and features expanded ride condition diagnostics, updated flowcharts and a new vibration and ride diagnostic quick reference guide. It also standardizes the terminology associated with these issues to improve communication between drivers and technicians.

    During the past 15 years, trucks and tractors have evolved into complex vehicles with many variations. Both fleet and driver expectations have risen dramatically during this time and companies now often specify premium vehicles to encourage driver retention. Many design and component changes have improved vehicle performance. But while overall ride quality has improved, elevated expectations have helped increase ride complaints.

    TMC’s Troubleshooting Ride Complaints manual helps equipment users and maintenance operations pinpoint issues that cause driver discomfort and reduced equipment performance such as vibration, shimmy, harsh ride, poor handling, pitch/backslap, instability, bounce/hop and vehicle hard to recover. Developed by TMC members and industry experts, the manual is the definitive guide for diagnosing commercial vehicle ride complaints. 

    Discounts available for multiple quantities/bulk orders. Customized covers also available upon request.

  • TMC Study Group Chairman Testifies to Congress on Challenges of Vehicle Electrification

    Taki Darakos, PITT OHIO’s fleet manager who oversees the acquisition and maintenance of 1,550 company-owned tractors and box trucks, testified before Congress on the technological, operational, and financial challenges fleets face as federal and state regulations mandate the adoption of battery-electric trucks. Darakos chairs the Technology & Maintenance Council's (TMC) S.11 Sustainability & Environmental Technologies Study Group.

  • Survey Report: Fleet Preferences for a Next Generation Tractor/Trailer Electrical Connector

    The American Trucking Associations’ Technology & Maintenance Council (TMC) has conducted a survey on behalf of its S.1 Electrical Study Group to assess fleet preferences regarding performance and characteristics for the next generation (NextGen) of tractor-trailer electrical and data connector(s) to be recommended as the successor to the current industry standard SAE J560 connector.

    The results of the survey were collected from a representative cross section of fleet operations. The fleets responding to the survey indicated a high-priority need for development of a NextGen connector that maintains backward compatibility with existing SAE J560-equipped vehicles, as well as a need in the short-to-medium time frame for new features and technologies that would be enabled by whatever is ultimately selected as the NextGen connector.

  • TMC Publishes Position Paper on NextGen Tractior/Trailer Interface


    This position paper lays out the technical performance needs for a new tractor/trailer electrical interface for both power and data, so as to provide a set of technical characteristics to facilitate advancement of trailer technology through modernizing the truck/trailer interface in a way that minimizes the burden on fleets and individual owner/operators, and allows for the best opportunity for successful industry adoption without causing unnecessary business disruption yet still provide the necessary expansions to accommodate future truck/trailer functionality.

    The S.1 Next Generation Tractor/Trailer Electrical Interface Task Force is utilizing these criteria in its continuing work to evaluate various proposals for the NextGen Interface for potentially replacing the SAE J560 connector with a new standardized interface.

    The Position Paper is availalble for download at:

  • TMC Releases Latest Standard Repair Time Labor Report for Commonly Performed Tasks

    ATA’s Technology & Maintenance Council (TMC) has released its latest “Fleet & Service Provider Average Standard Repair Time (SRT) Survey,” which was administered in the second half of 2023

     The purpose of the study was to aid in establishing baseline repair times that will improve shop productivity and profitability. This is the fifth year that TMC has conducted the survey, providing a four-year comparison of year-to-year SRT data.

    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).

    The list of top 10 most labor intensive tasks was dynamic as compared to last year, with "New Truck In-service" topping the list for 2023. Conversely, the list of top 10 least labor intensive tasks was dynamic as compared to last year, with "R&R generator/alternator belt" topping the list for 2023.

    The data collected for 2022 showed large increases in the times of per- forming repairs in many categories, whereas the data for 2023 shows labor times are stabilizing. Five new items joined the list in 2023. Seventy-one (71) tasks decreased in time to complete task; 24 increased; three were unchanged.

  • TMC Fleet Members Top Maintenance Concerns Continued to Shift in 2023

    The things that keep fleet managers up at night continued to shift through the end of 2023, according to a survey conducted by ATA’s Technology & Maintenance Council (TMC) — at least when it comes to TMC fleet members’ top maintenance worries. 

    More than 400 TMC fleet members were asked to share their current top five fleet maintenance concerns, based on a wide-ranging list of 85 possible choices from which to select. Of those responding, the following were identified as the top reported concerns in descending order, even though the list did not prove to be a clean top five:

    1. The top maintenance issue identified in the fall 2023  survey was technician staffing.
    2. Aftertreatment was identified as the number two maintenance issue facing fleets.
    3. Roadside breakdowns was identified by fleets as number three.
    4. Data management, new technology challenges, and vendor reliability were identified as number four (tie).

    New equipment availability was identified as number five.

    Roadside breakdowns, data management, new technology challenges, and vendor reliability appeared in the TMC top five list for the first time in the fall of 2023. New equipment availability returned to the top five list after being absent in the summer of 2023. It appeared in the top five in the spring of 2023.

    The list changed from the last time TMC surveyed fleet members on this question in the summer of 2023. At that time, members said their top five concerns were:

    1. Cost Containment
    2. Aftertreatment
    3. Technician Shortage
    4. Technician Staffing. Parts Shortage/Availability, and Emissions (tie)
    5. Outsourcing, Reliability, Technician Recruitment (tie)

  • TMC Survey - Average Standard Repair Times for Common Maintenance Tasks

    TMC Seeks Input in Assessing Average Standard Repair Times for Common Maintenance Tasks
    ATA’s Technology & Maintenance Council (TMC), through its S.5 Fleet Maintenance Management Study Group,  is conducting this member survey to assess and evaluate standard repair times (SRTs). The objective is to determine baseline repair times that will improve shop productivity and profitability.

    The survey is based on the Council’s Vehicle Maintenance Reporting Standards (VMRS), which will help the Council in aggregating reported SRT data. Participants are asked to provide their average times in hours for the 100 common maintenance tasks listed. NOTE: TMC is collecting data on actual labor/repair hours – not rates that participants may charge customers.

    Please provide data for as many of the 100 repair tasks as you can, based on your operation. You do not have to answer all 100 questions.

    We do ask contact information in order to follow up with you should questions arise, you may also choose to answer anonymously.

    All response will be kept strictly confidential and only aggregated results will be shared by TMC.
