Spending Quality Time With Your Vehicle

Identify The Problem  |  Check Transmission Fluid  |  Check Fluid Condition

Check The Engine To Transmission Communications Link | Check Electronic Data

Accurate Documentation


The automatic transmission, the most complex mechanical component in your vehicle, is directly connected to the engine, emission and computer control systems.

These systems, which combine to form the power train, are so interconnected that a malfunction in the transmission can appear as an engine, computer or electrical problem. Worse yet, a fault in the engine, computer or electrical system could be diagnosed as a transmission problem.

To avoid misdiagnosis, we need to invest quality time in your vehicle.

So please be patient.

We are doing a thorough job so that you can be sure your vehicle has been accurately diagnosed.

To understand what your technician is doing, we’ve outlined below the basic checks he must perform in order to make an accurate diagnosis.


1) Identify The Problem

Diagnosing and repairing your vehicle is our top priority.

In order to do that, however, we need to identify the cause of your complaint. That’s why our diagnostic procedure includes a few simple questions and a road test.

2) Check Transmission Fluid

The automatic transmission will not operate correctly unless it contains the correct amount of transmission fluid. If the fluid level is low, hydraulic pressures will drop and eventually cause serious damage to internal components. By checking the fluid level we can determine whether your cars’ malfunction may be due, in part, to a low fluid level; which is often times caused by a minor leak.

Too much fluid can also cause serious problems. When the fluid level is high enough to reach the spinning components inside the transmission, the churning action traps air in the fluid, causing it to foam. “Foamy” fluid increases oxidation and can reduce pump efficiency which could reduce internal pressures and cause serious problems like band and clutch failure.

3) Check Fluid Condition

The condition of the fluid can reveal a great deal about an automatic transmission. When the fluid is clean and red it usually means that the unit has not sustained any internal damage and that it has not been exposed to excessive heat.

If the fluid is still translucent but is slightly brown, it is worn and needs to be replaced.

If, however, the fluid is either brown and smells burnt or is no longer translucent, it indicates exposure to excessive heat, and a serious problem with either the cooling system or the transmission.

When the fluid is pink and has the consistency of a strawberry milkshake, it means that water has entered into the transmission. In most cases, water in the unit means that both the transmission and the cooling system will have to be repaired.

A sure sign of a serious transmission problem is black transmission fluid. When the fluid is black, it indicates a serious internal transmission problem.

4) Check The Engine To Transmission Communications Link

For an automatic transmission to operate properly, the engine and the transmission must communicate with each other at all times via a communications link.

This link, which can vary depending on the vehicle, the manufacturer and the transmission, can be a cable, a linkage, a vacuum line, an electric sensor or a switch.

The link tells the transmission what the engine is doing so that it can adjust accordingly. When the engine isn’t working hard—under light load or light acceleration—neither should the transmission.

Conversely, if the engine is under heavy acceleration or under heavy load, the transmission must respond accordingly.

When a poor communications link exists, it can cause hard or soft shifts, no shift at all or a torque convertor clutch malfunction. And because any of these conditions can cause a premature transmission failure, a thorough check of the communications link should never be overlooked.

5) Check Electronic Data

Most vehicles on the road today are equipped with a variety of sensors and electronic data gathering devices which include an on-board computer, throttle position sensor, MAP and BARO sensors, oxygen sensor and coolant temperature sensor. All of these electronic controls send and receive information which can effect the performance of both the engine and the transmission. As a result, specialized diagnostic tests and equipment may be needed to check these and other components to determine whether or not they are contributing to the problem.

6) Accurate Documentation

Part of any complete diagnostic procedure includes documenting the vehicles’ performance and condition. An accurate, well documented diagnostic procedure is critical to our technicians who may work on any number of different vehicles during the course of the day. Proper documentation is also invaluable when ordering parts, sourcing technical information and for future.
