How do I know If I Have a Transmission Problem?

Have you noticed patches of reddish clear fluid on your driveway after you pull out in the morning? Have you felt odd clicking or grinding sensations coming from your vehicle when you change gears? Have you heard weird whirring noises when you change gears? Or does your vehicle just decide to change gears on its own and you slip out of gear? If so, then it is likely that you have a transmission-related problem with your vehicle. But before you get too worked up, let’s try to figure out just how bad your transmission problem is.

Transmission Fluid

The first thing you should do if you think you have a transmission problem is check your transmission fluid, as insufficient levels or poor quality of transmission fluid can cause more damage to your vehicle and transmission. Transmission fluid is the lifeblood of your transmission. It keeps everything well lubricated and running smoothly – it is so important to have this checked if you are sensing you have transmission related issue.

Checking your transmission fluid is easily done. You can bring it in to Mister Transmission and we’ll do it for you quick, or you can do it yourself if you feel comfortable doing so. You want to check both the level of fluid and its quality. The fluid should be transparent with a reddish tint to it. If it is opaque or smells unpleasant, the fluid is degraded and should be flushed out and replaced.

Transmission Leaks

Topping up or replacing your transmission fluid could be all the fix you need for your transmission problem. However, problems with the fluid are often a symptom of a larger problem. For example, let’s say you top up your fluid but then two weeks later, your transmission problems reemerge. You check your fluid levels once again and are aghast to discover the fluid level has dropped once again.

In such a case, you have a fluid leak. With leaks, you will probably notice patches of transmission fluid on the pavement under where you parked your car. Leaks can be a minor transmission problem…or a big one. It depends on the size of the leak. A total reseal is obviously a much bigger job than a smaller, isolated area that needs resealing. But as far as transmission problems go, it could always be worse.

Wear and Tear

If your transmission fluid is foul smelling and opaque, your transmission problem might be caused by normal wear and tear. This would require an inspection to diagnose. Sometimes it’s as simple as replacing one or two accessible parts that have worn down and impacted the transmission fluid. Sometimes, it’s a bigger problem, and a more extensive repair job is required. To be sure, please bring your vehicle to your nearest Mister Transmission and we will be happy to complete a free multi-check to properly diagnose your vehicle.

Computer Problems

Nowadays, many transmission problems are, effectively, computer problems. If your vehicle has a computer-controlled transmission that is not shifting properly, it is often the result of the onboard computer sending incorrect signals due to a faulty sensor, or the transmission is not reacting to the command because of a bad connection or defective solenoid pack. These are not necessarily big transmission problems, but it will require a visit to a transmission shop that has the special equipment required to interface with your vehicle’s computer.

I want to give a huge thank you to Cecil and the team for going above and beyond to take care of one of my customers. My customer broke down in Golden with their 2015 Dodge Grand Caravan and was quoted an extremely high price for only a temporary repair. I didn't recommend going that route, so I called Cecil. Without hesitation, he said he would pick up the van on Monday. By Wednesday, he called to let me know he was dropping it off at my shop in Kelowna with a fully rebuilt transmission, complete with all the latest updates, ready for my customer to pick up. Cecil, Brandon, and Fred have done it again. Their commitment to customer service and doing the job right is second to none. Thank you for always looking after our customers. I look forward to many more years of working together and continuing to provide the best service possible.

Tanveer Singh
I had a great experience at Mister Transmission. I went in worried that my vehicle had a major transmission problem, but after inspecting it, they honestly told me they didn't believe the issue was related to the transmission. They didn't try to sell me unnecessary repairs, didn't charge me anything, and pointed me in the right direction instead. A special thank you to Sunny for being professional, patient, and genuinely honest. It's not every day you find a shop that values integrity over making a quick buck. That level of honesty has earned my trust, and I'll definitely be coming back if I ever need transmission work or any other car related work in the future. Highly recommended!

Ken Jarvis
I’ve seen how Kris treats his customers, very honest and accommodating, if the vehicle is not worth the cost of fixing. He tells them straight up. They make the decision not Kris. When I want an honest opinion or clarification that everything is good before the warranty from the manufacturer expires, I take it to Kris. Thank you so much for your service and professionalism 👍👍

⭐⭐⭐⭐⭐ I had an excellent experience at Mister Transmission thanks to Lorenzo and Dan. While they didn't actually perform any repairs on my vehicle, they took the time to thoroughly explain everything, answer all of my questions, and provide honest, knowledgeable advice without any pressure. It's refreshing to find people who genuinely care about helping customers understand their situation rather than just trying to sell a service. Their professionalism, patience, and expertise gave me complete confidence. I wouldn't hesitate to recommend Lorenzo and Dan to anyone looking for trustworthy and knowledgeable transmission specialists.
