Date: August 21, 2024 | 1:00 PM EST / 12:00 PM CST Presenter: Wayne Colonna, ATSG Transmission issues don’t always mean transmission malfunction. Often in-depth diagnosis reveals problems with other components that can make technicians believe the issues are transmission related. In this three-part series, ATSG experts will present case studies from their troubleshooting calls with professional technicians. Offering transmission diagnosis and repair support for shops, the Automatic Transmission Service Group encounters a broad spectrum of issues through its call center. This series will highlight vehicle-specific problems that can help you troubleshoot issues in your bays, and help you realize some of those transmission issues aren’t faulty transmissions after all.
