Why Is My Car Not Shifting Gears Properly? Common Transmission Issues

Have you noticed your car struggling to shift gears? Whether it hesitates, jerks, or refuses to move smoothly, this could be a sign of transmission trouble. The transmission is one of the most important components of your vehicle, responsible for transferring power from the engine to the wheels. If it fails, your car’s performance and safety could be at risk. Transmission problems can lead to costly repairs if left unchecked. At Mister Transmission, we specialize in diagnosing and fixing transmission issues to keep your car running smoothly. In this guide, we’ll explore the common reasons why your car may not be shifting gears properly and what you should do next.

Why Is My Car Struggling To Shift Gears?

Several factors can cause gear-shifting problems, and ignoring them can lead to costly repairs or complete transmission failure. One of the most common causes is low or contaminated transmission fluid, which can reduce the efficiency of your transmission system. Faulty transmission sensors may also contribute to shifting problems, preventing your vehicle from engaging gears properly. In manual transmissions, worn-out clutch components can be the culprit, while in automatic transmissions, malfunctioning solenoids can cause gear hesitation. Transmission overheating is another major issue, often caused by excessive loads or lack of fluid maintenance. If your car struggles to shift, professional attention is necessary to prevent further damage.

Common Transmission Problems That Affect Gear Shifting

If your car is struggling to change gears, it might be due to one of these common transmission issues. Low or contaminated transmission fluid can lead to delayed or rough shifting and unusual noises. Faulty transmission sensors can cause your vehicle to shift gears at the wrong time or even go into limp mode, restricting movement. Worn-out clutch components can make it difficult to engage gears smoothly, especially in manual cars. Malfunctioning solenoids can cause fluid mismanagement, leading to hard or delayed shifting. Transmission overheating may cause further mechanical damage if not addressed promptly by a professional.

Signs Your Transmission Needs Immediate Attention

Ignoring transmission issues can lead to major repairs. There are several warning signs to watch out for, such as slipping gears, where your car unexpectedly changes gears or struggles to stay in gear. Delayed response is another symptom, where the engine revs but the car doesn’t accelerate immediately. If you experience grinding or shaking while shifting, this could be an early sign of internal transmission failure. Transmission fluid leaks are another red flag, as puddles of red or brown liquid under your car indicate a serious issue. Dashboard warning lights, such as the check engine or transmission warning light, should never be ignored.

Automatic Vs. Manual Transmission Shifting Issues

Both automatic and manual transmissions can experience shifting problems, but the causes may differ. In automatic transmissions, common issues include sensor failures, solenoid problems, or low transmission fluid levels. A failing torque converter can also cause erratic shifting. In manual transmissions, problems often arise due to worn-out clutch components, misaligned gears, or faulty linkages. A failing clutch may cause difficulty in engaging gears or make the transmission slip. Regardless of your vehicle type, professional diagnostics are essential to determine the exact issue and prevent further mechanical damage that may result in costly repairs.

How Transmission Fluid Affects Gear Shifting

Transmission fluid plays a crucial role in smooth gear shifting by lubricating and cooling internal components. When fluid levels drop or become contaminated, your transmission may not function properly. A lack of sufficient fluid can cause gears to slip or hesitate, making it harder to accelerate. In extreme cases, a transmission may overheat, leading to potential long-term damage. Contaminated or old transmission fluid can result in increased friction between gears, causing rough shifting. Dirty or degraded fluid can also lead to transmission wear, resulting in costly repairs. Over time, sludge and debris can accumulate, further obstructing smooth gear transitions. Regularly checking and changing your transmission fluid is essential for maintaining transmission performance. A transmission fluid flush or refill at Mister Transmission can resolve many minor shifting problems before they escalate into serious transmission failures requiring expensive repairs. Our team ensures that your vehicle runs smoothly by using high-quality transmission fluid and professional servicing tailored to your car’s needs.

Warning Lights & Other Indicators Of Transmission Trouble

Your car’s onboard diagnostics system can alert you to transmission issues. The check engine light is one of the most common warning indicators that something is wrong with your transmission. Another crucial sign is the transmission temperature warning, which signals overheating problems. Other indicators include strange noises, burning smells, or unusual vibrations when shifting gears. If you notice any of these warning signs, you should take your vehicle to a professional transmission repair shop immediately. At Mister Transmission, our experts use advanced diagnostic tools to pinpoint issues and recommend appropriate solutions before they worsen.

Can Driving Habits Impact Your Car’s Transmission?

Yes! Your driving habits can significantly affect your transmission’s lifespan. Sudden accelerations and hard braking put unnecessary stress on the transmission, leading to premature wear and tear. Driving with a heavy load or towing beyond your car’s recommended capacity can cause overheating. Frequent stop-and-go traffic can also strain the transmission system, increasing the risk of mechanical failure. Ignoring recommended maintenance schedules can result in unnoticed issues escalating over time. By driving smoothly and following regular maintenance at Mister Transmission, you can extend your transmission’s life and avoid costly breakdowns.

When Should You Visit A Transmission Specialist?

If your car experiences shifting problems, it’s best to visit a professional transmission repair shop before the issue worsens. Signs that you need immediate help include gears slipping, grinding noises when shifting, and unusual delays in acceleration. If you smell something burning or notice fluid leaks under your vehicle, your transmission may be overheating or suffering internal damage. Mister Transmission offers free road tests and diagnostics, ensuring we identify the root cause of your transmission problem. Early detection and professional repairs can prevent further damage and save you from expensive transmission replacement costs.

Sanjay and Bailey (technician) are both amazing individuals to deal with.The customer service received from Sanjay is top notch and the knowledge and expertise and honesty from Bailey is incredible!I took my vehicle in there for a second opinion after already being to a different Mr. Transmission location for a diagnostic.Needless to say the outcome I received was the exact same from another location; being that there was absolutely nothing wrong with my CVT transmission (2018 Honda CRV) after being charged $180 and told that my transmission was the issue from my regular mechanic shop a couple days prior.I highly recommend Mr. Transmission (Exeter Rd location) 1000% to anyone and everyone who may be experiencing or believe to be experiencing transmission issues.Their knowledge, customer service, honesty, transparency, and expertise is amazing!Thanks so so so much guys for making my day great and leaving with a huge smile.

What an amazing team. Chris, Ron and the other wonderful man. My car broke down this afternoon at a gas station but before it broke down the battery warning light kept coming on so I got a boost and drove my car to buy a battery. Well started to drive my car and the battery warning light came on again so I heard that Mr transmission does free car diagnostics so decided to call them and had an appointment for 1: 00. Well I just drove my car straight down there and parked my car in their parking lot because I knew as soon as I shut my car off it won't start. Well these three guys come straight to my car as it was squealing as well. They did their diagnostic and it turned out it was my alternator. Well these guys went out of their way to fix my car on the spot. They only work on transmissions but Chris thought I needed a break and fix my car on the spot. I had the parts delivered and the guys worked on it for hours but only charged me under an hour's labor. Their garage closes at 5:00 but all three of these wonderful men stayed later until my car was running properly. There are no words to express the gratitude I have for these three men. Not too many places go out of their way at their own cost to help someone get back on the road. Finding a garage that's willing to help out in a pinch, especially with something outside their usual scope of work, and then stay late to make sure you're back on the road safely, is incredibly rare and special.

1000% without any doubt recommend Travis and his team for all your transmission needs!They are knowledgeable and honest!I stopped in there for a diagnostic and quote after paying $180 from my regular mechanic the day before who told me my issues (engine overheating and creaking noise when braking at low speeds) were a transmission issue.Travis took my vehicle for a drive and upon his return, he flat out told me that there was absolutely nothing wrong with my CVT transmission (2018 Honda CR-V)To say this made me incredibly happy would be an understatement. The honesty received here, especially being skeptical going in a woman alone was refreshing and top notch!Thank you so much for being a dependable and honest place for the community to bring their vehicle’s transmission needs to!

5 Stars – Outstanding Service and DedicationI have nothing but great things to say about the staff at Mister Transmission. I originally brought my car to a local shop, where they noticed a transmission leak that they believed was due to a crack in the casing. I took the car to Mister Transmission for further inspection.Although the source of the leak wasn’t immediately obvious, the team at Mister Transmission didn’t give up. They were determined to find the issue, and after four thorough attempts, they finally discovered that one of the plugs wasn’t seated properly.Their persistence and commitment to solving the problem really impressed me. I’m extremely thankful for their hard work and dedication to getting my car back in shape. Highly recommended!Lise G.
