Sonnax Welcomes Industry Experts at TASC Force Meeting

The Sonnax Technical Automotive Specialties Committee (TASC) Force recently met in Jasper, Indiana, to discuss the top trends and topics in the transmission industry. The event was attended by 45 people from 15 different companies across three countries (U.S., Canada and Sweden).

The TASC Force is composed of expert transmission rebuilders and technicians with a hands-on understanding of the latest units and industry developments. Working closely with Sonnax design engineers and technicians, participants contribute product ideas, test new fixes and troubleshoot results, then meet on a regular basis to compare findings. These individuals play an invaluable role in identifying the root causes of transmission problems and supporting the development of Sonnax transmission products for the automotive aftermarket.

Held at the Jasper Engines & Transmissions headquarters, the group toured the company’s new Power Drive Facility and followed up with a two-day business meeting. TASC members discussed dozens of new product requests for late-model units as well as some older repairs for legacy-type units. Jasper is a long-time contributor to the TASC Force.

The meeting also included a presentation by Sonnax Vice President of Quality, Continuous Improvement & Environmental Health & Safety John Kulungian. As an industry leader in the cutting-edge design, manufacture and distribution of the highest quality products, Sonnax is committed to excellence in every aspect of its operations. Kulungian has been instrumental in identifying new opportunities and engaging employee-owners in pursuit of this goal since joining the company in 2016.

“This was a great opportunity to share the progress and plans for quality and continuous improvement at Sonnax,” Kulungian said.  “The TASC workshop session on how Sonnax can improve our customers’ experience was well-received and actionable.”
