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.

Deepti Kochhar
I brought my 2018 Dodge Grand Caravan to Mr. Transmission Maple Ridge because it was leaking fluid badly and having trouble shifting gears. With only 124,000 km on it, I wasn't expecting such a major problem and was quite worried about the repair costs. The team found issues with the transmission and leaking cooler lines. They were very understanding of my budget and helped me find an affordable repair option. They also provided a courtesy car so I could continue going to work without paying for a rental. They promised to have my van ready in 4–5 business days and delivered right on time! My van is driving smoothly again, and I'm so relieved. Really appreciate how they handled everything, especially the courtesy vehicle and keeping the costs manageable. Thank you to the whole team at Mr. Transmission Maple Ridge. Definitely a shop I'd recommend!

Miranda B
Brought my vehicle here for a transmission fluid change and because it was over due the fluid was dirty so they allowed it to sit on a hoist for an extended period to drain which slowed down their work. I was educated as to how much mileage I should drive between servicing since it's a needy type of transmission. apparently lol. The cost was much cheaper than I would have paid at the dealer. Thank you for the quick service and educatuon. I'll be back next year.

Willy H
Mark explained everything over the phone from diagnostics to repairs and costs with zero sales pressure. I towed the vehicle to the shop and within the exact timeframe and money quoted it was fixed. Upon delivery there was an issue. The team dealt with the issue very quickly and with professionalism even though it caused them to work a bit after close. The transmission was completely rebuilt and they installed an 02 sensor at cost with zero labor charged that I had been putting off. When I returned for my 10 day inspection I was again met with kindness and professionalism. I was even given a oil change gift card for my trouble upon delivery which was very unexpected and appreciated. Thank you guys for being honest and straight forward and treating customers like they matter. I hope I never have to deal with transmission issues ever again but if I do it will be at Mister Transmission in St Thomas.

Del Peterson
I took my car into Mr Transmission to get a second opinion on my Mitsubishi as I was not happy with the customer service at the dealership. I booked a time to get it looked at and was thoroughly impressed with the technicians. The tech did his investigation and gave me his detailed diagnosis. The cost to repair was prohibitive but he had a few suggestions to try to see if we could get it resolved. While this was happening, I was waiting and another technician was working with the front end staff impressed me with his automotive knowledge across a large range of manufactures and years. I also witnessed a dealership dropping off a difficult transmission problem. If I have a transmission issue on any of our cars this is the place to come to. You can tell immediately that the staff has a deep, technical understanding of drivetrains and transmission engineering. If you want a shop that actually understands how a car works rather than just throwing parts at it, go here.

Vikas Bhardwaj
I had an excellent experience with Mr. Transmission Maple Ridge with my 2022 Mazda CX-5. My vehicle was jerking and not shifting properly, and I was really worried that something serious was wrong with the transmission and that I might be facing a very expensive repair. I decided to give Mr. Transmission Maple Ridge a call, and right from the first conversation, I felt much better. Kyle was extremely helpful and knowledgeable. He listened to my concerns, explained a few possibilities, and suggested bringing the vehicle in for their free Multi-Check and road test. When I arrived, the team inspected my vehicle, performed a road test, and scanned it for trouble codes, all at no charge. They could feel the jerking during the road test, but no transmission fault codes showed up. They noticed the transmission fluid was quite dark and recommended starting with a fluid change rather than jumping straight into an expensive transmission repair. I really appreciated their honest approach. After changing the transmission fluid, my Mazda started shifting smoothly again, and the jerking was gone. What a relief! They also recommended coming back after about 10 days for a follow-up recheck to make sure everything was still working properly. That really showed me they care about their customers and the quality of their work. I'm extremely happy with the service I received. The entire team was friendly, professional, honest, and genuinely helpful. They didn't try to sell me an expensive repair I didn't need, and they took the time to find a sensible solution. I would highly recommend Mr. Transmission Maple Ridge to anyone experiencing transmission problems. It's refreshing to find a shop that puts customer satisfaction and honest advice first. Thank you, Kyle, and the entire team for your excellent service!
