Reaming Update: Chrysler Solenoid Switch Valve & Plug Kits

One of the more prevalent Sonnax product support phone calls revolves around the Chrysler switch valve and plug bore, and how to salvage the valve body by addressing bore wear with available Sonnax tools. This has been a long, strange trip – especially for the .420" dia. spool version, for which Sonnax offers multiple kit and reaming options. We took a much more straightforward approach on the .453" dia. valve, which we have now duplicated on the .420" version to better serve builders.

Previously on the .420" version, a specific reaming sequence was required to avoid casting scrappage. If the (outer) switch valve plug portion of the bore required reaming, it had to be reamed first using either F-92835-TL18 with the patented VB-FIX reaming fixture or by using bench tool kit 92835-RM. After that, excess wear at the (inner) solenoid switch valve portion of the bore could be addressed using F-92835-TL with the VB-FIX. This paves the way for installing oversized solenoid switch valve 92835-21 and oversized plug kit 92835-18K.

If the (inner) switch valve bore was accidentally reamed first, the bore would not be the right size to guide the reamer used for the (outer) plug portion of the bore, so any wear at the plug bore section could not be addressed. Since the outer portion of the bore typically wears faster than the inner portion, this results in a scrapped casting.

The Sonnax approach with the .453" dia. setup does not have this reaming sequencing issue. If only the (outer) plug bore portion is worn, simply use reamer 92835-RM22 to recondition the bore, then install oversized plug kit 92835-22K. If wear at both the (outer) plug section and (inner) switch valve bore section is noted, use reamer tool kit F-92835-TL31 in conjunction with the VB-FIX, then install oversized solenoid switch valve and plug kit 92835-31K. Much easier!

A similar system has recently been developed for the .420" dia. version. If wear at both the plug bore and switch valve bore is noted, use new reaming tool kit F-92835-TL32 with the VB-FIX, then install oversized solenoid switch valve and plug kit 92835-32K (see chart on part page for details).

Of course, Sonnax will still provide the previous tooling and valve system, but this new method is much preferred for improved end results and ease of use that will enable your customers to get back on the road and keep on truckin’!

Sonnax Honored for Outstanding Worksite Wellness Programs

Sonnax once again has been recognized for the quality of its worksite wellness efforts by the Governor's Council on Physical Fitness & Sports and Vermont Department of Health. The employee-owned company will be presented with the Governor’s Excellence in Worksite Wellness Award at the March 25 Worksite Wellness Conference in Burlington, Vt.

“Worksites that promote healthy eating, physical activity, tobacco use cessation, and breastfeeding, contribute to the overall health and wellness of all Vermonters, and they are one of the key reasons we are routinely rated the nation’s healthiest state,” said Health Commissioner Harry Chen, MD.

The awards are designed to highlight and recognize what worksites from around the state are doing to promote the health and wellness of their employees. The organizations which receive the awards vary in size, industry and location but they all have a common thread: a commitment to workplace wellness.

One of 92 Vermont businesses considered for this award, Sonnax is dedicated to offering an at-work solution delivering high-quality worksite wellness that engages the employee, reduces risk, lowers cost and results in a happier, healthier workforce. The company offers onsite wellness coaching, challenges and education sessions aimed at helping employees take charge of their physical, emotional, social and spiritual wellbeing.

“Many people don’t realize that most chronic disease is preventable and related to lifestyle habits, which means we have more control over our own current and long-term health than we realize,” said Tamara Golden, Sonnax’s Driving Wellness health coach. “By educating and supporting employees in making healthy choices, they can not only be more productive in their work, but also live out their other dreams and aspirations unhindered by chronic illness.”

Sonnax Purchases Valve Body Xpress Sonnax Purchases Valve Body Xpress

The employee-owners of Sonnax Industries are pleased to announce the acquisition of Valve Body Xpress (VBX) and Valve Body Xtras of Paulsboro, N.J. Founded in 2002, VBX is a leading remanufacturer of automatic transmission valve bodies and solenoids. Valve Body Xtras is a VBX subsidiary focused on valve body components.

According to Sonnax President & CEO Tommy Harmon, this acquisition combines the resources of two successful companies to better meet the repair challenges of increasingly sophisticated modern transmissions. Sonnax is well-known worldwide in the industry for its innovative engineering, exceptional quality and outstanding technical support and training. The volume of valve bodies rebuilt by VBX and the company’s hands-on remanufacturing expertise opens the door to expanded Sonnax product development and testing capabilities. The transmission aftermarket will benefit from this collaboration, whether a shop chooses to rebuild their valve bodies with Sonnax parts or purchase a VBX rebuilt unit.

Valve Body Xpress President Tim LaCerra will remain with VBX in the position of Vice President of Remanufacturing. The company will continue to operate independently in New Jersey, and its 35 employees will become shareholders in the Sonnax Employee Stock Ownership Plan (ESOP). According to LaCerra, this will allow him to exit his ownership role in VBX while providing tremendous growth potential and an equity stake in the company to the VBX employees who helped achieve its tremendous success.

No major changes are planned for VBX in the near term.

“Valve Body Xpress is a successful growing company,” said Harmon. “We will continue to allow them to do what they do best while exploring opportunities for synergies and discovering areas where Sonnax can provide guidance to VBX and vice versa.”

Sonnax Acquires New R&D Center

A third facility recently joined Sonnax headquarters and distribution centers in Bellows Falls, Vt. On July 7, the employee-owned company purchased a former manufacturing space located only a quarter mile from existing Sonnax sites to house the company’s research and development teams.

“I am very excited to have the room to expand”, said Sonnax Senior Vice President of Development Steve Jaussaud. “We continue to grow, and have been getting tight on space. This facility will help us establish a great R&D center suited to our diverse product lines. As an engineering-driven company, this will allow Sonnax to become even better at product development and meeting our customer’s needs.”

The newly acquired building at 10 Spencer Drive in Bellows Falls contains 26,000 sq. feet of open space that will become the new home of the Sonnax engineering, product line management and technical support teams. The site will be completely renovated in the coming months to accommodate dedicated shop, testing and quality control areas, plus office space for approximately 35 employees. Space currently used in other Sonnax buildings for these activities will be freed up to accommodate growth in other areas of the company.

The building was sold to Sonnax by Chroma Technology Corp., an employee-owned manufacturer of interference filters located near Sonnax headquarters. Prior to Chroma’s ownership, Woodlan Machine operated out of 10 Spencer Drive for nearly 30 years. The shop has long provided machining services to Sonnax, and continues to do so out of a smaller, nearby facility.

Sonnax Named a Best Place to Work in Vermont Sonnax Named a Best Place to Work in Vermont

The employee-owned company of Sonnax Industries, Inc., was recently named one of the Best Places to Work in Vermont by the Vermont Business Magazine. Sonnax previously won this honor in 2012, the first time it participated in the annual statewide survey and awards program recognizing company workplace excellence.

“The entire team at Sonnax is very proud and honored to receive this award,” remarked Sonnax President & CEO Tommy Harmon. “I believe this award represents success in executing one of the strategies of our mission statement: ‘provide our employees with a rewarding career experience that is respectful and challenging’.”

The awards program is designed to identify, recognize and honor the best places of employment in Vermont, benefiting the state’s economy, its workforce and businesses. The program is presented in partnership with the Vermont Chamber of Commerce, the Vermont Department of Labor, the Vermont Department of Economic Development, the Society for Human Resource Management (SHRM) - Vermont State Council and Best Companies Group.

Companies from across the state began the two-part process in 2013 to determine the Best Places to Work in Vermont. The first part consisted of evaluating each nominated company's workplace policies, practices, philosophy, systems and demographics. The second part consisted of an employee survey to measure the employee experience. The combined scores determined the top companies and the final rankings. Best Companies Group managed the overall registration and survey process in Vermont, analyzed the data and used their expertise to determine the final rankings. Twenty-seven companies in all made the 2014 list of Best Places to Work in Vermont.

“We already believed we were one of the best places to work in Vermont, and receiving this recognition confirms that belief,” said Harmon.

Automakers Agree to "Right to Repair" Deal

Automakers have agreed to adopt a new "Right to Repair" law (based on the law in Massachusetts) as a national standard.

This law will:

  • Require automakers to make available to repair shops the same vehicle repair information they give to dealers
  • Allow repair shops to purchase that data with an ordinary computer over a standardized, Internet-based service
  • Require automakers to offer a nonproprietary interface for diagnosing problems with vehicles, starting in the 2018 model year

These new rules suggest that, by 2018, independent shops will have access to OE data without having to pay each auto manufacturer for a proprietary interface. Anyone with a standard internet connection can have access to the same data as a dealer for the same price as a dealer. The auto manufacturers agreed to this system rather than face a patchwork of up to 50 state-mandated solutions. This certainly appears to be good news for the independent aftermarket!

Solve these issues by installing the new Sonnax oversized B2 apply control valve kit 47740-27K which will restore the necessary hydraulic clearances required for proper valve function.

NEW! GM 6L45-6L90 Center Support Seal Kit

In GM 6L45, 6L50, 6L80, 6L90 units, the rubber seals between the center support in the case and the machined surface of the valve body are prone to leakage over time. This can result in continuous line pressure and lube flow loss, as well as clutch apply leakage in Reverse, 2nd and 6th.

Requiring no special installation tools, the new Sonnax center support seal kit 104740-14K will correct these issues by preventing any leakage from occurring.

TASC Force® Meeting

The Sonnax TASC Force® met in June following the 2013 ReMaTec Exhibition in Amsterdam, The Netherlands, for a new round of discussion about the latest transmission units and worldwide industry developments.

The Sonnax Technical Automotive Specialties Committee (TASC) Force is an international group of expert transmission rebuilders and technicians. Working closely with Sonnax design engineers and technicians, TASC Force members contribute product ideas, test new products, troubleshoot results and get together regularly to listen, discuss and compare findings.

Koyo®/Torrington® Bearing Notice

The automotive aftermarket has long been familiar with Torrington bearings. Although most people know that Torrington is a company that manufactures these bearings, the term “Torrington bearing” has become synonymous with needle roller thrust bearings. “Torrington bearing” has become a generic term describing a type of bearing as much as it indicates a manufacturer who produces those bearings.

The Torrington Company was established in 1898 in Torrington, Conn. It was an independent company until an acquisition by Ingersoll Rand Corp. in 1968. In 2003, Torrington Bearing was sold to the Timken Company, which produced Torrington brand bearings until 2009. In 2009, JTEKT Corporation of Japan acquired the Torrington bearing line – including the manufacturing plants and tech center along with 3,400 employees – from Timken. Torrington became part of the JTEKT’s Koyo Bearings.

Throughout these changes in ownership, the Torrington brand remained the unquestioned leader in needle roller bearings to the automotive and industrial markets, and Sonnax has proudly supplied Torrington bearings to our customers for many years.

As part of the Torrington sale by Timken to JTEKT, Koyo was permitted to use the Torrington brand name for three years. At the end of 2012, that three-year agreement expires and these products formerly known as Torrington bearings will be marketed solely under the Koyo brand name. Despite the Torrington brand name reverting to Timken, these Koyo bearings are the same OE Torrington products, produced by the same people, using the same processes, in the same U.S. factories.

Koyo Bearing is the Torrington legacy, and you can count on Sonnax providing you with the same great OE quality you’ve always received under the Torrington brand….only the name has now changed to Koyo.

Sonnax Hosts International TASC Force® Meeting Sonnax Hosts International TASC Force® Meeting

Forty-seven members of the Sonnax TASC Force® gathered May 7 and 8 in Vermont to discuss current and future challenges facing the aftermarket transmission industry. Sonnax was pleased to host the meeting for the first time in many years at its company headquarters in Bellows Falls.

"This year's TASC meeting was very exciting for all of us here at Sonnax," said Mark Kaplan, Sonnax Transmission Specialties Product Line Manager. "It gave us the opportunity to showcase all of the improvements that we have made at our facilities in Vermont."

The Sonnax Technical Automotive Specialties Committee (TASC) Force is an international group 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, TASC Force members contribute product ideas, test new designs and troubleshoot results, then meet on a regular basis to compare findings. Members play an invaluable role in identifying the root causes of transmission problems and supporting the development of Sonnax transmission products for the automotive aftermarket.

The two-day meeting started with tours of the Sonnax Distribution and Technical Center and nearby corporate headquarters, which includes office, manufacturing and quality control facilities. Technical roundtable discussions followed, during which TASC members from 18 shops shared feedback from the field.

"We continue to get new product ideas from the group which includes the need for electronics and solutions for late-model transmissions as well as a host of converter items," said Kaplan.

TASC Force® Holds International Meeting TASC Force® Holds International Meeting

The Sonnax TASC Force® met in Glasgow, Scotland, Oct. 9-11, 2011. Sixteen TASC members from the U.S. and eight European countries met with Sonnax personnel to discuss the state of the global transmission industry. TASC member John Mackie and his wife Dawn, of Mackie Transmissions in Glasgow, were hosts for the event. Festivities opened with a bus tour of the Scottish countryside on Sunday, Oct. 9. Highlights of the tour included Stirling Castle, the Trossachs regions of the Scottish Highlands, Lock Lomond and a tour of the Glengoyne Distillery.

The meetings began in earnest on Monday morning with updates on the progress of projects resulting from previous TASC Force meetings. A number of products originally suggested by the TASC Force are in varying stages of development by Sonnax. The meeting continued with the popular "round table" discussion where each TASC member presents a summary of issues they face, the solutions which are working for them and potential product suggestions which can help our entire industry deal with those issues.

The meeting also included in-depth discussions of vehicle electronics and the challenges those products present to the transmission industry. "The input of our global TASC Force members is invaluable," said Sonnax President & CEO Tommy Harmon. "They see many of the later model transmissions before they reach the U.S. Accessing their information early in the process helps Sonnax make sure the products needed by transmission and torque converter rebuilders are available when these units become prevalent in the North American market as well as in other parts of the world."

The next meeting of the Sonnax TASC Force has been tentatively scheduled in spring 2012 in Vermont. The Sonnax Technical Automotive Specialties Committee (TASC) Force is composed of experienced transmission rebuilders and technicians who value technical innovations and have hands-on understanding of the latest units and industry developments. From around the globe, the best minds in the transmission industry willingly share their know-how, with the understanding that everyone benefits when good ideas and products emerge from centuries of combined transmission wisdom.

The Sonnax TASC Force® held its first meeting of the year April 29-30, 2011, at Jasper Engines & Transmissions in Jasper, Ind. The semi-annual gathering is an opportunity for aftermarket automatic transmission experts from around the world to examine problems facing the entire industry and discuss solutions.

The Sonnax Technical Automotive Specialties Committee (TASC) Force is composed of experienced transmission rebuilders and technicians who value technical innovations and have hands-on understanding of the latest units and industry developments. These professionals meet regularly to share their know-how, contribute product ideas, test new products and troubleshoot results with the understanding that everyone benefits when good ideas and products emerge from centuries of combined transmission wisdom.

Sixty participants from seven different countries attended the recent TASC Force meeting. Altogether, more than 22 companies specializing in transmission and torque converter rebuilding were represented. The presence of many torque converter technicians and specialists prompted a new level of discussion about problems and repairs outside of the transmission, such as transfer cases, torque converters and driveshaft slip yokes. TASC members also focused closely on strategies for improving the quality of component testing and CAN (Control Area Network) communication.

TASC meetings are held twice per year, typically with the spring meeting in the United States and a fall meeting held abroad. The next 2011 gathering is planned for October at Mackie Automatic Transmissions in Glasgow, Scotland.

TASC Force® Meeting

The Sonnax TASC Force® held a semi-annual meeting Oct. 15-16, 2010, in Lucerne, Switzerland, bringing together an international group of transmission experts for two days of technical talks hosted by TASC member Adrian Marty of Automaten-Meyer AG.

Expert transmission rebuilders and technicians from around the world make up the Sonnax TASC Force (Technical Automotive Specialties Committee). Working alongside Sonnax engineers and technicians, they willingly share their hands-on knowledge of the latest units and industry developments to generate product ideas, test new parts, troubleshoot results and discuss and compare findings. Their efforts help provide answers and repairs for the entire transmission industry.

The TASC meeting began with a full day of discussion focused on new Sonnax projects, current transmission challenges and product proposals. Sonnax Product Line Manager Mark Kaplan noted that many of the new parts released in 2010 were a direct result of the group's European meeting the fall before. TASC members at that time had expressed a clear need for TR60-SN, ZF6HP26 and 5R55N valve body components, and the Sonnax team responded with the timely release of new repairs.

"We've been getting lots of great new project ideas from the European members of TASC Force," said Kaplan. "They have many opportunities to see newer units in their shops long before we see them here in the States."

The TASC meeting continued the second day on the floor of the Automaten-Meyer AG remanufacturing facility with hands-on demonstrations of new products and previews of those in progress. Bob Warnke, Sonnax V.P. of Technical Development, demonstrated rebuilding techniques for the new Aisin AW five- and six-speed valve bodies which incorporate linear solenoids for critical clutch-to-clutch shift timing.

The Sonnax TASC Force will hold its next meeting in Spring 2011 at Jasper Engines and Transmission in Jasper, Ind.
