Transmission failure can be a costly and frustrating experience for car owners. According to the article, the average cost of repairing a transmission failure is around $1,500 to $2,000.
The cost of a transmission failure can be broken down into several components, including labor costs, parts replacement, and diagnostic fees. For example, a transmission overhaul can cost anywhere from $800 to $2,000, depending on the type of vehicle and the extent of the damage.
A transmission failure can also result in additional costs, such as towing fees, rental car expenses, and lost productivity. In some cases, the cost of a transmission failure can be so high that it's more cost-effective to replace the vehicle altogether.
Causes of Transmission Failure
Transmissions can fail due to a defect, old age, or damage from an unusual event. This can include racing, hard use, or towing without proper maintenance and servicing.
A defect in the transmission's valve may cause forward gears to stop working, while reverse gear still functions. This is often identified through a transmission scan.

Lack of servicing, blocked filters, or overheating can cause burnt, dirty, or old fluid in the transmission. This can lead to a slipping transmission, overheating, and delays in engaging the gear.
Burnt fluid can sometimes cause internal damage if not identified on time, requiring replacement of damaged parts. Checking for clutch or metal debris in the fluid pan can help determine the extent of the damage.
Internal problems, such as a faulty valve or transmission, may require rebuilding or replacement, costing between $1,600 to $3,500 at a repair shop or $400 to $700 if done yourself.
Symptoms and Issues
If your semi truck is acting up, there are some telltale signs of transmission trouble to look out for. Trouble shifting, such as slipping gears while driving or the transmission popping into neutral on its own, is a common issue.
Strange noises like clunking, grinding, thumping, or humming, especially when the truck isn't in gear, are also a red flag. Transmission fluid leaks are another sign of trouble, and excessively dirty transmission fluid can cause problems too.

A sluggish clutch that stays engaged even after you let up on it and grinding gears during shifting are other symptoms of transmission issues. If you notice any of these signs, it's essential to address the problem promptly to avoid costly repairs.
Here are the top 3 signs of transmission problems to look out for:
- trouble shifting
- strange noises
- transmission fluid leaks
Overheating
Overheating is a serious issue that can cause permanent damage to your vehicle. If you notice smoke or a burning smell, it's likely due to burning coolant, oil, or transmission fluid.
This can be caused by a low transmission fluid level, dirty or burnt fluid, a blocked filter, or driving under immense load. Overheating can also be triggered by a malfunctioning cooling line or oil cooler.
If left unchecked, overheating can lead to a failed transmission, which can be a costly repair. In fact, diagnosis fees at a repair shop can range from $75 to $125.
It's essential to identify and diagnose overheating immediately to prevent permanent damage to your vehicle.
Vehicle Moves with Shifter in Park

If your vehicle moves even with the shifter in park position, it's likely caused by a worn out or damaged parking pawl, or a bad rear U-joint. This can be a safety hazard, so it's essential to address the issue promptly.
A diagnostic at the repair-shop can cost between $50-$65, but if you decide to have the repairs done there, the diagnostic charges may be waived. The repair-shop will charge you around $500-$1,000 for parking pawl replacement and $75-$115 for U-joint replacement.
You can also try to replace the parking pawl yourself, which will cost you $45-$90. Replacing the U-joint yourself is a bit more affordable, with an average cost of $10-$25.
Recognizing Problems
Trouble shifting is a common symptom of transmission problems, with signs including slipping gears while driving, between shift revving, or the transmission popping into neutral on its own.
A malfunctioning transmission can be caused by old, dirty, burnt, or low transmission fluid, as well as an open electrical circuit or failing solenoids.

Other red flags include strange noises, such as clunking, grinding, thumping, or humming sounds, especially when the truck isn't in gear.
Transmission fluid leaks are another sign of trouble, and excessively dirty fluid can cause problems too.
A sluggish clutch that stays engaged even after you let up on it is also a telltale sign of transmission trouble.
Some common signs of transmission problems include:
- Slipping gears while driving
- Between shift revving
- Transmission popping into neutral on its own
- Clunking, grinding, thumping, or humming sounds
- Transmission fluid leaks
- Excessively dirty transmission fluid
- Sluggish clutch
- Grinding gears during shifting
Issues
If you notice anything unusual with your transmission, it's essential to address the issue right away to avoid costly repairs. Some problems are fairly easy to fix and could extend the life of the transmission if they're not allowed to get worse.
Leaking or dirty fluid can be a significant issue, but replacing seals and topping off the fluid might cost hundreds of dollars, maybe as much as $1,000. This is still a fraction of the cost of replacing a transmission.
Worn or broken transmission mounts can cost as much as $225 for the part alone, and labor costs will add to that. Solenoids are another repairable transmission issue, costing over $400, even with labor.

Overheating is a critical issue that can cause permanent damage to your vehicle. If you notice smoke or a burning smell, or if the transmission fails, it's likely due to overheating. This can be caused by low transmission fluid, dirty or burnt fluid, a blocked filter, or driving under immense load.
Other irregular shift problems can be caused by an electrical malfunction or faulty sensors. You can perform an initial assessment at home, but a full scan of electrical and computer systems, and all sensors, will require a visit to the repair shop. This can cost between $75-$125.
Shifter lever locking itself in the park position may be due to a fault in the brake-pedal position or shift interlock switches, or a blown fuse. Diagnostic charges may be waived if the repair shop carries out the repairs as well.
Here are the top 3 red flags that indicate transmission problems:
- trouble shifting—slipping gears while driving, between shift revving, or transmission pops into neutral on its own
- strange noises—clunking, grinding, thumping, humming, and other unusual sounds, especially when the truck isn’t in gear
- transmission fluid leaks—plus, excessively dirty transmission fluid can cause problems, too
Types of Transmission Problems

There are several types of transmission problems that can occur in a vehicle. Abnormal shifts or wrong gear shifts can be a sign of a malfunctioning transmission, often caused by issues with the transmission fluid or electrical circuits.
Trouble shifting, such as slipping gears or transmission pops into neutral on its own, is another common problem. This can be caused by a variety of factors, including dirty or low transmission fluid.
Other signs of transmission trouble include strange noises, such as clunking, grinding, or thumping sounds, especially when the truck isn't in gear. A sluggish clutch or grinding gears during shifting can also indicate a problem.
Here are some common causes of transmission problems:
- Old, dirty, burnt or low transmission fluid
- Open electrical circuits
- Solenoids failure
- Failed automatic gear shifting mechanism
- Internal seals leakage
- Torque converter malfunction
Irregular Shift Problems
Irregular shift problems can be frustrating and confusing, but they're often caused by simple issues that can be diagnosed and fixed at home.
You might notice your transmission downshifting randomly and then going back to normal, which could be due to an electrical malfunction or faulty sensors.

A custom diagnosis at a repair shop can cost between $75-$125, but you can start by checking the basics at home.
If you suspect a linkage problem in the shifter, you might notice the vehicle rolling forward even with the shifter in neutral position.
This could be caused by a loose shifter linkage, a damaged shifter cable, or a misdirected shift indicator.
Diagnosing the cause of the problem yourself can be a cost-effective option, with diagnostic fees ranging from $40-$50.
If the issue is a loose shifter linkage, you can tighten it yourself at no additional cost.
However, if the problem is caused by a damaged shifter cable, replacement costs can range from $125-$250 at a repair shop.
You can also purchase and replace the cable yourself for $35-$80.
Knowing what ails your vehicle and being able to identify a problem can give you confidence when dealing with a repair shop and save you money on repairs.
Here's a list of common symptoms of irregular shift problems:
- Random downshifting
- Vehicle rolling forward in neutral
- Misdirected shift indicator
- Loose shifter linkage
- Damaged shifter cable
Keep an eye out for these symptoms, and you might be able to diagnose and fix the issue before it becomes a bigger problem.

If you're unsure about what's causing the irregular shift problems, it's always best to consult a repair shop for a proper diagnosis.
A diagnosis at a repair shop can cost between $40-$125, depending on the complexity of the issue.
Once you know what's causing the problem, you can decide whether to fix it yourself or take it to a repair shop.
Either way, being informed and proactive can save you time, money, and frustration in the long run.
Reverse Gear Failure
Reverse Gear Failure can be a real nuisance, especially if you're used to relying on it for easy parking or reversing out of tight spots.
A leakage in the valve body can cause the reverse gear transmission to stop working, even if the forward gears are still functioning properly.
Diagnosing the problem at a repair shop will typically cost around $75-$150, and if the valve needs to be repaired, the costs will be similar to those mentioned earlier.
Types of

There are two main types of transmissions: Manual and Automatic. Manual transmissions require you to shift gears yourself with a stick shift.
Automatic transmissions change gears automatically, making it a convenient option for many drivers. You simply select forward or reverse and let the car handle the rest.
Automatic transmissions come in many varieties, with Geared transmissions being the most common. Geared transmissions are what most people are familiar with.
Continuously Variable Transmissions (CVTs) are another type of automatic transmission, offering a smooth and seamless driving experience. They work by using belts and pulleys to provide an infinite number of gear ratios.
Dual Synchronous Gear (DSG) transmissions are a specialty type of automatic transmission, offering quick and precise shifting. Some high-performance vehicles use this type of transmission for its speed and agility.
Battery-electric vehicles also have a form of transmission, although they don't have multiple gears like traditional vehicles do. Instead, they use electric motors and sometimes a single gear to propel the vehicle forward.
