If your automatic car is not shifting gears smoothly, it could indicate a serious issue with your transmission system. It's important to address these problems promptly to avoid further damage and costly repairs. At Mango Automotive & Diesel in Las Cruces, NM, we provide advanced diagnosis and repair for transmission issues and get your vehicle back to peak performance. Our auto repair technicians have extensive expertise to ensure reliable and efficient repairs. 

Common Causes of Transmission Shifting Problems

Automatic transmissions rely on a complex system of components and fluids to function smoothly. Shifting gears can become difficult when any part of this system encounters a problem. By recognizing these problems early, you can get the repair done at a transmission auto repair shop and ensure that your vehicle continues to operate efficiently.

Low or Dirty Transmission Fluid

Transmission fluid lubricates the moving parts, provides hydraulic pressure for shifting, and helps cool the transmission. When the fluid levels are low or the fluid becomes dirty, it can lead to shifting problems and potential transmission damage. If your vehicle is experiencing shifting issues, one of the first things to check is the transmission fluid level. Common signs of low transmission fluid include:


Delayed or Sluggish Shifting: If your car hesitates before changing gears or shifts with unusual delay, it may be a sign of low fluid levels.


Grinding or Slipping Gears: Low fluid can cause the transmission to struggle with gear engagement, resulting in grinding noises or slipping gears.


Warning Lights: Some vehicles have a transmission temperature light that activates when the fluid level is low or the fluid is overheating.


Dirty transmission fluid can also cause significant shifting issues. It can become contaminated with debris, metal particles, and other impurities. This contamination can reduce lubrication, affect hydraulic pressure, and cause overheating.


Regular checks and timely fluid changes can prevent shifting problems and keep your vehicle running smoothly. Mango Automotive & Diesel provides reliable auto repair in Las Cruces, NM. Our expert technicians can assess your transmission fluid levels and condition, performing necessary maintenance or replacements to ensure your transmission functions correctly.


Worn Transmission Components

Transmission shifting problems can also arise from worn or malfunctioning components within the transmission system. Understanding the role of these components and recognizing the symptoms of malfunctioning parts can help address issues before they lead to more serious damage.


Clutches and Bands

Clutches and bands control the engagement and disengagement of various gears. These transmission components can wear out due to normal use or lack of maintenance and can cause shifting issues such as:


Harsh or Jerky Shifts: If you notice that the transmission shifts roughly or abruptly, it could be a sign of worn clutches or bands.


Slipping Gears: The transmission may slip out of gear or struggle to maintain gear, especially during acceleration if the clutch or band is worn.


Difficulty in Shifting: You might experience trouble when trying to shift gears, with the transmission either failing to engage or engaging slowly.


Solenoids and Sensors

Transmission solenoids and sensors regulate the flow of transmission fluid and ensure accurate gear shifts. Solenoids control fluid flow to various parts of the transmission, while sensors monitor the transmission’s performance and provide feedback to the control module.


Faulty solenoids or sensors can cause unpredictable or inconsistent shifting. It can also activate transmission warning lights if sensors detect issues or if solenoids are malfunctioning. Performance issues such as transmission slipping, delayed shifts, or difficulty in engaging gears can also be caused by malfunctioning solenoids or sensors.


If you’re experiencing any of these issues, contact our auto repair shop in Las Cruces, NM, for expert diagnosis and repair services.


Faulty Torque Converter

The torque converter functions as a fluid or hydraulic coupling between the engine and transmission. It relies on the principle of fluid dynamics to transmit power without the need for a solid mechanical connection. It facilitates the smooth shifting of gears by regulating the flow of transmission fluid and adjusting the amount of torque delivered to the wheels. A well-functioning torque converter ensures that your vehicle accelerates smoothly and that shifts occur without hesitation or jerking. The common symptoms of a failing torque converter include:


Slipping or Shuddering: The slipping or shuddering sensations while driving, especially during acceleration, may indicate a problem with the torque converter. This can result in poor power transfer and erratic shifting.


Overheating Transmission: A failing torque converter can cause the transmission to overheat due to inefficient fluid flow and increased friction. If you notice your transmission temperature gauge rising or smell burning fluid, the torque converter might be the issue.


Delayed or Rough Shifts: A faulty torque converter can cause delays in gear shifting or make shifts feel rough and inconsistent. This happens because the converter is not properly regulating the fluid flow or torque transfer.


Unusual Noise: Grinding, whining, or other unusual noises coming from the transmission can signal a failing torque converter. These sounds occur when the converter’s internal components are damaged or worn out.


At Mango Automotive & Diesel in Las Cruces, NM, our experienced auto repair technicians can accurately diagnose and repair issues related to a faulty torque converter. The use of advanced diagnostic tools helps us to pinpoint the problem and provide effective solutions to restore your transmission's performance.


Electrical Issues

Faulty wiring or damaged sensors can impair the communication between the transmission and the vehicle's control systems. These components send crucial information to the transmission control module (TCM) regarding the vehicle’s speed, throttle position, and other important parameters.


Damaged or frayed wiring can interrupt the electrical signals that control the transmission, leading to erratic shifting or a complete failure to shift. Corroded or loose connections can also cause intermittent issues, making it difficult to pinpoint the exact problem. Transmission sensors provide vital information to the TCM. If these sensors malfunction, they can send incorrect data, resulting in improper shifting, slipping, or harsh gear changes.


Transmission Control Module (TCM) Issues

The Transmission Control Module (TCM) is the brain of the automatic transmission system. It processes data from various sensors and controls the shifting of gears based on this information. Problems with the TCM can lead to a range of transmission issues.


Faulty TCM: A malfunctioning TCM can cause erratic or delayed shifting, difficulty in selecting gears, or even a complete failure to shift. The TCM may need to be reprogrammed, repaired, or replaced depending on the severity of the issue.


Error Codes: When the TCM encounters problems, it triggers diagnostic trouble codes (DTCs) that can be read with a scan tool. These codes help auto repair technicians identify issues within the transmission control system.


At our transmission auto repair shop, we conduct thorough diagnostics to identify problems with wiring, sensors, or the TCM and provide reliable repair solutions to fix these issues. Ensuring that your transmission’s electrical systems are functioning correctly is essential for smooth and efficient gear shifts.


Overheating

Transmission overheating can lead to significant damage if not addressed promptly. When a transmission operates at temperatures higher than its designed limits, it can suffer from various problems that affect its performance and longevity.


Several factors can contribute to transmission overheating:


Insufficient Transmission Fluid: Transmission fluid is crucial for maintaining optimal operating temperatures and ensuring smooth gear changes. Low fluid levels can cause the transmission to overheat as it leads to inadequate lubrication and cooling.


Clogged Transmission Cooler: The transmission cooler helps regulate the temperature of the transmission fluid. If the cooler becomes clogged or blocked, it can hinder the fluid’s ability to dissipate heat effectively, leading to overheating.


Heavy Towing or Overloading: These activities can put additional strain on the transmission. The increased workload generates more heat, which can cause the transmission to overheat if it is not designed to handle such stress.


Faulty Thermostat: The thermostat maintains the temperature of the transmission fluid. A malfunctioning thermostat can lead to improper fluid temperatures, contributing to overheating issues.


Overheating can have several negative effects on the transmission's shifting performance, such as delayed shifting, slipping gears, or erratic shifting. At Mango Automotive & Diesel in Las Cruces, NM, we specialize in diagnosing and repairing transmission overheating issues. Experienced technicians at our auto repair shop perform thorough inspections to identify the cause of overheating and provide effective maintenance and repairs.
