Truck Transmission Problems

Your truck's automatic transmission is a critical system that requires appropriate maintenance and attention from you to guarantee long-term performance. Many individuals are unaware that replacing an automatic transmission might be more expensive than replacing an engine. To help you  prevent an extensive repair, we’ve put together a list of symptoms that can be used to identify possible transmission problems early. 

The information provided here is intended to assist you. You can make an educated choice on what to do if you have the correct information.

1. A sense of grinding or rattling when shifting gears

Usually, your automatic transmission will shift effortlessly from  one speed to the next, . As your truck shifts gears, you shouldn't notice any grinding, slippage, or shaking. These indicators may seem minor until a transmission begins to have issues. But, at this point, it's wise to pay attention since it'll almost certainly become worse with use. It's time to bring it in and look like you're already experiencing some jarring feelings as the truck changes. When automatic gearboxes have defective gears, they usually become worse over time.

This is a far more severe issue, and time is of the essence. Make an appointment with a skilled diesel  transmission expert as soon as possible.

2. When in gear, the truck will not engage or react

Is your truck responsive right away when you put it in drive or reverse, or does it take a moment to “think”? When you put the truck in drive or reverse, does the gearbox not engage? Both of these concerns might indicate a problem, and it might signal an issue with your fluid, such as it having lost its thickness and therefore it’s protective characteristics. In this scenario, a suitable fluid exchange would be needed.

On the rare occasion, your gearbox not engaging may be caused by your truck’s computer syste.  YOu can try resetting your truck’s system.  This is done by turning off the power for around 30 minutes. If this doesn't work, it's time to call in a professional diesel transmission technician.

If your automatic gearbox doesn't engage or shifts slowly, it's time to have it checked out. The majority of issues resulting from these symptoms are small, but it's essential to find out for sure so that it doesn't cost thousands of dollars later.

3. Makes noises in neutral: whining, buzzing, or clunking

You may have transmission issues if you suddenly hear a whining, buzzing, or clunking sound beneath your truck that you've never heard before. That problem might be small, but it could also indicate something more serious.

The breakdown of your automatic transmission fluid might create several sounds coming from your transmission. This fluid is responsible for lubricating many mechanical gears and components. That fluid loses its protective characteristics over time. Friction from unlubricated components can  cause the automatic transmission mechanism to break down.

An internal element may have failed if you hear clunking sounds and think it's coming from the transmission. If this is the case, you should have a certified automatic transmission repair check at it as soon as possible.

Some sounds might be caused by a minor issue with your transmission fluid, while others could be more significant. If you have the opportunity, check the fluid in your automatic gearbox. If your fluid is low, you can top it up, but it’s best to come into the shop as soon as possible to speak with one of our transmission mechanics to make sure nothing else has been impacted

4. Your truck smells hot, as if it’s burning

A burning odor should not be present in your truck, which is something to worry about. Overheated fluid is one of the most prevalent reasons for a burning transmission odor. The fluid in your gearbox plays a critical part in keeping this pricey and complicated system working smoothly, and it's mostly about lubrication.

When the lubricating properties of your transmission fluid deteriorate with time and miles, it allows detrimental friction between all components. Friction causes parts to break down, accumulate debris, and form sludge. All of these issues, when combined, result in a complete transmission failure, and that is both inconvenient and costly.

Low transmission fluid levels are sometimes the culprit. Because, unlike motor oil, transmission fluid does not degrade over time in most trucks, this is generally caused by a leak. This might also happen if the incorrect fluid has been used previously in your truck.

If your transmission emits a burning odor, it's essential to take action before it becomes a significant issue. Call or come in to find out what's wrong and put your mind at rest.

5. Sliding gears

Is your truck slipping out of gear or losing traction when you need it the most? If this is the case, there is a severe safety issue. It's frightening if your gearbox slips in and out of gears while driving, and you have to give it the throttle to prevent a problem.

The computer in your truck directs the transmission when to shift from one gear to the next, and it instructs your truck when and how much power to transmit to the wheels. If anything is wrong here, the signal isn't being transmitted correctly.


These are some of the most common transmission issues you can get in your truck. if you experience any of these, make sure that you seek the assistance of a diesel truck repair specialist. They will be able to diagnose your truck and work with you to repair any issues.
