Transmissions: Repair or Replace?

The factors to consider before deciding the best option.


Today’s commercial transmission are very sophisticated products. For this reason, proper training of technicians is more important than ever. In the case of the Allison authorized service network, factory-approved training is required of all technicians that perform transmission repairs. 

Attempts to repair transmissions by under-trained or untrained techicians can lead to excessive downtime, misdiagnosis or can even cause additional problems or catastrophic and expensive failures. 

Beyond being a necessity for making accurate repairs, proper training is also required in order to take advantage of key diagnostic capability of Allison products.

Allison authorized service locations offer Trans Health service for recent vintage transmissions. Trans Health is a diagnostic process wherein the computer can be utilized to check and measure key wear components of the transmission without requiring any level of transmission disassembly. The computer can warn of impending clutch failures and thereby enable customers to schedule repairs on a more convenient basis. 

What’s more, replacing worn components before an actual failure occurs greatly reduces the total expense to the customer. Such a pre-emptive repair enables the worn part to be inspected and replaced as necessary, before it fails and causes a chain reaction of neighboring part failures.

VITAL ELEMENTS

In the repair process, an accurate diagnosis is most critical in making proper fixes, as well as minimizing downtime. For dealing in the complex world of electronic controls, Allison has created diagnostic tools to assist in determining the root cause of problems. 

The need for proper tooling and corresponding training is evident when considering situations wherein inadequately equipped or trained technicians misread the symptom and thereby waste time and add expense by pursuing false corrections. 

For example, symptoms may manifest as improper transmission shifting, when in reality the problem is not an internal transmission issue at all but rather a problem caused by faulty vehicle wiring, a cooling system issue or possibly another powertrain component control system malfunction. Very often, only knowledgeable and properly equipped technicians can pinpoint and correct the true cause of problems, and do so in a timely fashion. 

Equally important for making quality repairs is the need to use quality parts. At authorized Allison service locations, only genuine Allison parts are used for repairs. 

In Allison's opinion, non-genuine parts often fail prematurely and in doing so, can cause expensive secondary damage. Any upfront cost savings attained through the use of inferior parts quickly disappears when a failure is compounded or a repeat failure occurs. 

From simple repairs to complete transmission replacement, the vital elements in quality service are the same today as they have always been, but likely to a higher degree than ever before. Quality repairs are the result of proper training, proper tooling and quality replacement parts. 

The combination of these service elements will insure long-lasting and cost effective repairs.

Bendix increases focus on remanufacturing

Bendix Commercial Vehicle Systems has launched a new business unit to focus on and expand its remanufacturing output.

Each Bendix business unit had been responsible for both its original equipment and aftermarket products. Now, the new business unit consolidates all remanufacturing efforts as part of the company’s aftermarket business.

Bendix develops and supplies leading-edge active safety technologies, air brake charging and control systems and components under the Bendix brand name for medium and heavy duty trucks, tractors, trailers, buses and other commercial vehicles throughout North America.

Steve Mance, Bendix vice president and general manager of the Charging group, says reasons for establishing the new unit include offering buyers lower-priced alternatives to new parts and ensuring long-term and peak-demand product availability.

“We can remanufacture products that went out of OE production as many as 30 or 40 years ago,” he says. “And in peak OE years, we can ensure product availability when other manufacturers are out of capacity because we’re producing remanufactured parts.”
