Diagnostics is one of the most misunderstood processes in automotive repair. The perception is there is a magical “Diagnostic Machine” we attach to your vehicle and the solution to your problem is produced out of the “Machine”. In reality diagnostics is a procedure to systematically use test equipment and information systems to determine the cause of a vehicle’s ailment.

The testing tools, information systems, and technician knowledge requires a commitment to training and equipment expenditures. Glenwood Auto Service has made and continues to make that commitment.

Antilock Brake Systems (ABS)

Check Engine Light

“CHECK ENGINE LIGHT”, “SERVICE ENGINE SOON”, commonly referred to as a malfunction indicator light (MIL) by the manufacturer. These warning lights indicate that an error was logged in the computer system that controls a vehicle system. Severity of the problem is not always obvious to the driver. Errors that illuminate the MIL light can change the operation of the computer system. A fuel efficiency decline, unusual transmission operation, or component damage can be a result of inattention to the MIL light.

We take pride in our ability to offer complete diagnostic capability on all domestic and import vehicles.

Engine Drivability

My car shakes when I’m at a stop sign. When I push on the gas it doesn’t go…These complaints are examples of some of the “Drivability” problems you might experience.

Transmission Filter & Fluid

A transmission filter’s purpose is to stop the flow of harmful debris before it reaches the internal components of the transmission. Over time debris accumulates in the filter causing it to become plugged and therefore reducing its effectiveness.

Your transmission filter and fluid should be changed together on a regular basis.

Simply changing the filter, without doing a flush, leaves anywhere from 30% to 50% of the old fluid in the transmission which prematurely reduces the effectiveness of the new filter.

In addition, the old fluid does not lubricate as effectively as the new fluid, thereby causing premature wear to the internal moving transmission components.

We recommend that you service and flush your transmission every 40,000km or every two years.
