What Causes Transmission Problems?

What Causes Transmission Problems

Transmissions are tricky. They are incredibly intricate and complex. And this truer now than ever before. With the advent of computers and the increased digitization of automobiles, transmissions can be more confusing than ever. So when a transmission begins to act up, it can be a really tricky proposition to figure out just what the problem is.

Transmission Problems

Transmission problems come in all different sorts and varieties. Sometimes you know you have a transmission problem. Other times, you know there is a problem with your vehicle, but you can’t be sure it’s the transmission. And sometimes, there can be something wrong with your transmission but you have no idea that your vehicle is running at nonoptimal levels.

If you hear harsh noises when you shift gears, it’s a pretty clear sign that you have a transmission problem. Ditto for slipping, erratic shifting, and late or early shift patterns. This is often (but not always) caused by wear and tear on your transmission. But there are other transmission problems as well.

Wear And Tear

Wear and tear is a major cause of a variety of transmission problems. One of the best ways to see if you have a transmission problem is to check your transmission fluid. If it’s clear red, you should be OK. If, however, your transmission fluid is discoloured or has an unpleasant smell, your transmission is likely suffering from wear and tear. If discoloured fluid is coupled with other symptoms and problems, this might require an internal inspection of your transmission.

Computers And Sensors

As mentioned before, transmissions have become increasingly computerized in recent years. Overall, this is a good thing, but it does mean that transmission problems can be an even more complex and challenging conundrum. A major cause of transmission problems is when the computer system is sending incorrect signals due to a faulty sensor. Another common problem with computerized transmissions is when the transmission does not react to the command because of a bad connection or defective solenoid pack.

Technical Diagnostics

As mentioned earlier, many transmission problems are the result of old, dirty, or insufficient levels of transmission fluid. But because of the role of the computer, or just because transmissions are inherently complex machines, the cause of a transmission’s problems may not be easily assessed right off the bat. A comprehensive diagnostic process may be required.

At Mister Transmission we have access to state of the art diagnostic equipment, which allows us to offer the fastest and most accurate findings about what’s going on inside your vehicle’s transmission. Our technology can interface with a vehicle’s computer system to determine the specific transmission problem. The first step in assessing your transmission involves your technician connecting the diagnostic equipment to your vehicle’s on-board computer. This will produce a code stating where the problem lies. Next, we take the vehicle for a test drive so that we can evaluate its performance in real-time. While more comprehensive and hands-on evaluations may yet be required, our technology is an important tool in determining the right starting point for further investigations to figure out the cause of your transmission problems.

Denielle Tooley
I’m very pleased with my experience at this shop! I brought my beloved Mustang here for a transmission rebuild. They were very helpful in explaining the process to me, communicating with the warranty company on my behalf, and keeping me updated on timelines without me having to ask for updates. I was delighted to pick up my vehicle and see they had gone above and beyond by washing it and putting some gas in it! All the staff I spoke to were pleasant and easy to work with. Mark took the time to explain things to me and ensured my full understanding throughout the process. I was encouraged to come back in about a week and a half for a final check up/inspection at no cost, which makes me feel even better about their confidence in their work.
