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.

Liz Gosselin
My 2016 Dodge Journey would not pick up speed without revving at a really high rpm. Transmission was slipping and revved hard in reverse. Took it in to Mister Transmission on Portage Ave knowing I most likely needed a new transmission. Got them to check and yes I needed one. They gave me the money back for the diagnostic and I paid for the new transmission. They also provided me with a courtesy car for 5 days. They did the work so quick and made sure my car was fixed properly. My car runs like a brand new vehicle. It picks up speed, rpm is good, and doesnt shake in reverse anymore. Special thanks to Phil and the team for repairing my car and getting it back to working order. They also have a good warrenty on the new transmission. Completely worth the money. Thanks guys.

Shane Whitehead
I cannot say enough good things about dealing with Mister Transmission. Their staff are extremely knowledgeable and went above and beyond while working on my transmission. They brought out the filter and pan and explained what they suspect happened before even pulling the transmission apart. They were kind enough to take me into the shop and allow me a visual of what I was looking at and was able to walk away more knowledgeable than going in.They gave me a ride home in their personal vehicle as they did not have a shuttle and didn't even mention taking a taxi as if it wasn't an option.They stuck around late on a Thursday of a long weekend (Friday being the holiday) to ensure the vehicle was returned to me before the long weekend and leaving me without a vehicle for an additional 4 days.I will be returning for fluid changes and any other concerns with other vehicles in the future.

Christian Karimlou
I had a serious issue with my transmission on my 2017 Civic and brought it here. The team at Mister Transmission did an amazing job diagnosing and fixing everything properly. They explained the issue clearly, kept me updated, and the customer service was top tier from start to finish.They replaced everything needed and got my car running like new again. Was charged for a very fair price for the amount of work that was done.Honest, professional, and reliable I highly recommend them if you’re dealing with any transmission problems.
