Bringing You More:

In 1976 my parents, Les and Carol Langsford, founded M D Publications, Inc. They published their first issue of Muffler Digest in August of that year after their son Rokey opened a muffler shop and found no trade journals that significantly helped business owners in that segment of the aftermarket. I worked here at the time, stuffing envelopes, emptying trash and learning our family business – and even put in some time at my brother’s shop.

In 2013 I proudly became the president and CEO. We will continue to work hard to provide you with the automotive aftermarket’s most-reliable information. Enhancements to aid our readers are continual. I hope you will visit our new and improved websites, UndercarDigest.com, TransmissionDigest.com and AutoTECHexpo.net. Our new digital presence is easier to read and to navigate. The sites will adapt to tablets and mobile devices of any size. Further, we have constructed a more user-friendly environment for use of those registering for the annual Auto TECH expo.

Keep reading Transmission Digest and Undercar Digest for more updates on the new ways we are finding to help aftermarket retail shops improve by staying informed and profitable.

From the first, the goal at M D Publications has been to provide crucial information to shop owners and technicians alike, while keeping you up to date with industry information and news.

The sponsors make it possible for our magazines to be delivered, free of charge, directly to your shop. We hope that when you purchase products, tools or equipment you will consider them first.

A Brief History:

M D Publications Inc., parent company of Auto TECH expo, Undercar Digest and Transmission Digest, has a long history of providing accurate news and up-to-date technical and management information to the automotive-repair industry. This published information was complemented by the formation of an industrywide transmission trade show in 1984 and an undercar trade show starting in 1987. The two mega-events merged in 1996, and Showpower Expo was born! Today the refocused Auto TECH expo includes top manufacturers and distributors in the auto-repair industry, plus technical and management seminars that examine the core developments in all aspects of automotive diagnostics and repairs in our industry.

M D's start took place more 35 years ago in 1976, when founders Les Langsford (1928-1993) and Carol Langsford (1933-2012) published their first issue of Muffler Digest in August of that year. Being the predecessor of Undercar Digest, Muffler Digest was well received by muffler-shop operators. In the past, these shop operators could find only limited information and advertising in general-repair trade magazines about the exhaust-system replacement business.

M D introduced Transmission Digest in 1981 – meeting the needs of another segment of the repair market that had been ignored. It too was a hit with its readers. Shortly afterward, M D began publishing Transmission Tech/Talk, a monthly eight-page technical bulletin, for the industry.

With muffler shops beginning to offer more and more undercar repairs, Muffler Digest was revamped in 1987 and renamed Undercar Digest, adding brake and chassis repairs to the editorial mix. Today the magazine features technical information on a wide array of repairs with emphasis on diagnostics and drivability.

In 1990, M D began offering Brake Tech/Talk and Alignment Tech/Talk, two monthly technical bulletins that deal with topics such as ABS and all-wheel alignment.

With its strong heritage of determined leaders, M D Publications has strengthened its longstanding position of being the best information provider to the industry. Continuing the original guidance of its founders and present team members, the company has come to be widely recognized as the premier publisher of automotive aftermarket trade publications, whose dedicated team, state-of-the-art production facilities, efficient mailing operations, data processing and quality circulation are the envy of the industry.
