Frequently Asked Transmission Repair and Service Questions

Why do check engine lights come on?

There are many reasons why your check engine light will come on. It could be as simple as a loose gas cap or a dirty air filter, or even worn spark plugs. The check engine light comes on when a registered trouble code has been detected in your car or truck’s internal computer.

Can I drive with a transmission leak?

It depends on the rate of transmission fluid loss. A minor or slow leak will allow you to drive, as long as you maintain the level in the normal range. But it’s always good practice to bring your vehicle in and get the small problem fixed before the small problem turns into a big one! A transmission will operate “normally” until the fluid loss is a quart or more, but watch out for fluid leaking on hot exhaust or the catalytic converter. Many newer vehicles, the transmission fluid can only be checked by raising the vehicle.

How much will it cost to fix my transmission?

Estimating the accurate cost of a transmission repair without an inspection can be difficult. The cost to fix any transmission will vary depending upon the make, model, and what actually has to be repaired. At Sun West Transmissions & Radiators, we are happy to road test your vehicle at no charge as the first step to a proper transmission diagnosis.

How often should I service my transmission?

For a complete service, manufacturers recommend different intervals. Typically, service is recommended every 30,000-50,000 miles. Check your vehicle owner’s manual to find out what your vehicle manufacturer recommends, or give Greg a call at 623-842-0806 and he’d be glad to help you!

What does a transmission cooler do, and do I need one?

If you tow a trailer or overload your vehicle, you may require a transmission cooler. Many options are available depending your needs and driving conditions.

How do I know if I have a transmission problem?

The following symptoms may indicate that your vehicle’s transmission requires service:

  • Check Engine Light Is On
  • Low Or Leaking Transmission Fluid
  • Noise Coming From The Transmission
  • Transmission Is Slipping (Engine Speed Not Correlation With Road Speed)
  • The Vehicle Does Not Move (Does Not Move Or In A Particular Direction)
  • Does Not Shift Or Change Gears

How often should I have my transmission checked?

Transmission fluid levels should be inspected at every engine oil change and often may go undetected. Most often the transmission can’t be seen and checking the fluid sometimes can be difficult. Please feel free to call Greg at 623-842-0806 and ask about checking your transmission. For preventative maintenance it is recommended that you visit Sun West Transmissions and Radiators annually for a FREE Multi-Check Inspection.

What if there is a pink or reddish puddle under my car?

You may be leaking transmission fluid. It is important to give Greg at Sun West Transmissions & Radiators a call at 623-842-0806 to determine if the vehicle should be driven or towed in for service.

What's my car's transmission fluid supposed to look like?

How can driving conditions affect my vehicle's transmission?

Severe hot or cold weather and driving conditions affect the life expectancy of your transmission. Regular servicing of your transmission will help prevent premature failure and promote a longer transmission life.

What does Scanning or Diagnostics of a transmission do?

This procedure involves attaching a diagnostic computer to a terminal in your vehicle. This device is used to communicate with your computer to determine if any trouble codes are present and to “read” the output from numerous electrical sensors that feed information to the computer. All of this information is useful in determining the integrity of the electrical control system for the transmission. Scanners have become required in the diagnostic process.

Is it best to drive in overdrive or normal drive?

Your transmission is controlled electronically by it’s on board computer and is intended to be driven in overdrive unless conditions indicate otherwise.

What does the term "slipping" really mean?

Simply put, it means the engine speed is not equal to the vehicle speed.

My older vehicle's transmission shifts into reverse OK, but has a delay going into drive when cold.
