Decoding Common Signs of Transmission Problems Before They Escalate

May 3, 2024 by Denver Express Car Care

When you get into your car, you expect it to go. You’ve got a busy day ahead, with lots to think about on your drive into work. 

But what if your car doesn’t go? 

Picture this: You cruise onto the highway, and your engine starts racing. You can hear the transmission isn’t shifting gears. It whines and grinds, but no movement. You know something is wrong. You pull over to the side of the road … it’s going to be a long day. 

Transmission problems can be the most stressful, expensive repair issues to deal with. 

But the good news is you don’t have to wait for transmission problems to escalate before you take action. Warning signs start to appear long before problems occur. Let’s cover a few of them so you can start taking action now. 

Ignoring Maintenance

One of the most common reasons transmissions fail for all vehicles is not following manufacturers’ maintenance recommendations when caring for the engine and transmission. They push the mileage when scheduling fluid and filter changes. They push off maintenance until they “have more time.” 

Here in Colorado, that can be dangerous, especially if you enjoy our outdoor lifestyle. You frequently head up into the hills for skiing, hiking, and biking. You tow campers and boats for a weekend of play. These harsh conditions are taking a toll on your vehicle’s inner-workings. Without proper fluid levels, it no longer lubricates properly. Without clean filters, your vehicle won’t cool properly, leading to overheating, failure, and a host of other mechanical issues.  

Decoding Common Signs of Transmission Problems Before They Escalate

Fluid Leaks

The second most common way your transmission will warn you of pending issues is through a transmission leak. Transmission fluid leaks can occur at various points in the transmission system, including seals, gaskets, or cooler lines. Leaks lead to low fluid, burnt fluid, overheating, and eventual damage that will no longer be repairable by just adding fluid. 

A transmission fluid leak is usually red, ranging from light pink to a brownish color, depending on its age. If you notice this color leaking from your car and pooling underneath the front of your car, it’s likely a transmission leak. Identifying the source of the leak and repairing it promptly is crucial to maintaining proper transmission function and preventing fluid loss, which can lead to overheating and damage. If it isn’t caught early, it can lead to needing a replacement or rebuilt transmission. 

Strange Noises

Vehicle noises differ depending on where the problem lies. But if you hear anything out of the ordinary, pay attention. Can you describe it as humming, buzzing, whining, or clunking? Those are the most common ways people describe transmission problems. With hundreds of parts inside the transmission system, even one loose bearing can throw the entire system off. Each sound signals a different potential issue:

  • Grinding noises typically occur when there’s a problem with the gears, such as worn synchros or teeth. These sounds often indicate that the transmission is having difficulty synchronizing the gears, which can lead to further damage if not addressed.
  • Whining or humming noises might indicate low transmission fluid or a worn-out bearing. Both scenarios can lead to serious transmission issues if left unattended.
  • Clunking sounds when shifting gears could be a sign of worn-out or damaged transmission mounts, which can cause the transmission to shift unexpectedly and result in further damage to surrounding components.

Only  a thorough inspection of the system can isolate where the noise is coming from and point to where the problem originates. Trust your mechanic to get to the root of the problem. 

Warning Lights

Thank goodness for modern cars. Their technological advancements have done wonders helping you solve issues before they escalate and turn into bigger problems. Depending on your make and model, you may have 20 to 30 dashboard lights ready and waiting to alert you to potential problems. Don’t ignore them – they light up for a reason. 

Dashboard warning lights such as the Check Engine Light or Transmission Temperature Light are designed to alert you to potential issues with the transmission system. The Check Engine Light is one of the most common lights to illuminate; it can signal many different issues in your car. Bringing your car in early for an inspection means we’ll catch the problem before it escalates, potentially saving you money on more severe problems. 

Slipping Gears

Do you hear the engine revving higher than it should when driving down the road? Does it lack power or sound like it’s slipping gears? People often describe this in many ways, yet you’ll know when it feels like your car is clunking as you speed up and slow down. 

Transmission slipping occurs when the transmission fails to maintain a consistent gear, resulting in the engine revving higher than usual without a corresponding increase in vehicle speed. This can be caused by many things, including worn-out clutch bands, clutch packs, or torque converters. You can prevent slipping transmission by maintaining your fluid levels and ensuring you don’t have any leaks. When you find a problem, get it fixed immediately. 

Burning Smell

A burning smell is never a good sign. In most cases, a burning smell comes from overheated transmission fluid, or leaking fluid. Low fluid levels cause excessive friction which exacerbates the situation. Ignoring this smell could lead to severe transmission damage or failure.

Solenoid Issues

Solenoids in cars perform many different functions, from helping start the engine to assisting in shifting gears. They control upshifting and downshifting while you drive. If solenoids are damaged or wear down, it can damage your transmission, cause shifting problems, leading to diagnostic codes showing up in your vehicle’s computer. 

A car’s computer sends 100s, if not 1000s, of signals to the solenoids a second, telling your vehicle how much pressure it needs, when to shift, how fast to shift. This level of action eventually wears parts down, causing you to notice it in the way your car shifts and moves. It may be as simple as replacing the solenoid if it has become defective. 

Do you Have Transmission Problems? 

From the moment you notice a first sign of a problem, your best course of action is to schedule an inspection. It’s the easiest way to stop issues early before they rise in significance and escalate to a more costly problem. 

Have a transmission issue? Let’s chat. Give us a call, and we can schedule a time to inspect your car, find the issue, and make the repair. It’s the best way to get you on the road again. It’s the best way to bring peace of mind to your drive.
