What is an Automatic Transmission?

An automatic transmission, also called an automatic, shifts gears automatically without you having to operate the clutch. Unlike a manual transmission, where you control when to shift, an automatic transmission shifts gears completely independently based on engine speed, speed, and accelerator pedal position. This provides greater comfort, especially in heavy traffic, and in modern models, can also be more fuel-efficient than manual shifting.

There are different types of automatic transmissions:

• Conventional automatic (torque converter) – Uses a torque converter and oil pressure for shifting. This is the traditional automatic transmission that has been in use for decades.
• CVT (Continuously Variable Transmission) A continuously variable transmission without fixed gears, it works with belts and cones. It's especially popular with Japanese brands like Toyota, Nissan, and Honda.
• DSG/DCT (Dual Clutch Transmission) A robotized dual-clutch transmission combines the comfort of an automatic with the efficiency of a manual. Used by Volkswagen (DSG), Audi (S-tronic), Ford (Powershift), and others.
• AMT (Automated Manual Transmission) – A manual transmission with automated clutch and shifting, often cheaper but less comfortable.
• E-CVT – Electric variant mainly in hybrid cars, uses planetary gear sets and electric motors.

Each type has its own characteristics, advantages and disadvantages, and specific maintenance requirements. At Faay Auto Groep, we have experience with all types of automatic transmissions and have the right equipment and knowledge to maintain and repair them.

Common Automatic Transmission Problems

Automatic transmissions are complex systems that require regular maintenance. Here are some of the most common problems:

1. Jerky or Stuttering Switching

If your automatic transmission jerks when shifting or doesn't shift smoothly between gears, there could be several reasons for this:

• Contaminated transmission oil – The most common cause. Old or dirty oil loses its lubricating properties and can clog valves and channels.
• Low oil level – Too little oil causes insufficient oil pressure and poor lubrication.
• Worn couplings or plates – In conventional automatic transmissions, the internal friction plates wear out.
• Faulty solenoid valves These regulate oil pressure and shift points. If they are defective, the transmission will not shift correctly.
• Software problems – Modern machines may require a software update.
• Worn clutch (with DSG) – DSG gearboxes have dry or wet clutches that can wear out.

Symptoms: Jerks when shifting, harsh transitions between gears, delayed response to throttle, vibrations while driving.

2. Slipping Gear

If the engine revs but the car accelerates little or not at all, the transmission is slipping. This means that the power isn't being fully transferred from the engine to the wheels.

Possible causes:

• Too low oil level in the gearbox
• Worn friction plates or slats
• Faulty torque converter
• Leaking seals causing loss of oil pressure
• Faulty oil pump
• Severely contaminated or burnt transmission oil

Symptoms: High engine revs without gear, burning smell, sudden loss of revs, car does not respond to accelerator pedal.

3. Warning light is on

Modern automatic transmissions are equipped with sensors that continuously monitor operation. If a problem is detected, a warning light will illuminate on the dashboard (often a gear symbol or "AT" light).

Common error codes:

• P0700 – General Transmission Malfunction
• P0715-P0770 – Acceleration Sensor and Solenoid Valve Problems
• P0868 – Low oil pressure in transmission
• P17XX – Mechanical problems (especially with DSG gearboxes)
• P0793 – Gearbox sensor faulty

At Faay Auto Groep, we can read error codes with professional diagnostic systems and pinpoint the cause. Ignoring the warning light can lead to serious damage and significantly higher repair costs.

4. Gearbox Does Not Shift or Remains in Emergency Mode

Some automatic transmissions switch to an "emergency" or "limp mode" when serious problems arise. In this mode, the car often remains in a fixed gear (usually 2nd or 3rd) and you cannot shift. This is a protective mode to prevent further damage.

Causes of emergency running:

• Serious error code detected by the computer
• Faulty gearbox sensor
• Electrical problems (wiring, connectors)
• Faulty TCU (Transmission Control Unit – gearbox computer)
• Critically low oil level
• Gearbox overheating

What to do: Drive as little as possible and visit Faay Auto Groep immediately for a diagnosis. Continuing to drive in limp mode can cause permanent damage.

5. Strange Noises from the Gearbox

Unusual noises are often a sign of wear or a defective part:

• Screeching sound – Often caused by too low oil level or a defective oil pump
• Knocking noise when shifting – Worn clutches, engine or gearbox mounts
• Rattling sound – May indicate loose parts or worn bearings
• Whistling while driving – Possible defect in the torque converter or bearings
• Clicking sound – Defective solenoid valves or mechanical components

Ignoring noises can lead to total transmission failure. Schedule an inspection immediately if you hear any unusual noises.

6. Transmission Oil Leakage

Red or pink oil stains under your car indicate leaking transmission fluid (ATF). Common leak points:

• Worn seals and gaskets
• Leaking cooler lines
• Damaged crankcase or seals
• Faulty dipstick tube (if present)
• Cracked cooler (often integrated into the radiator)

Leaks must always be repaired. A low oil level leads to wear, slippage, and ultimately gearbox failure.

Maintenance of Automatic Transmissions

Regular maintenance is crucial for the longevity of your automatic transmission. Unfortunately, it's often overlooked, resulting in costly repairs.

Change transmission oil

The most important maintenance for an automatic transmission is changing the transmission fluid (ATF). This fluid has multiple functions: lubrication, cooling, cleaning, and hydraulic pressure buildup for shifting. Over time, the fluid becomes contaminated and loses its properties.

Replacement interval:

• Conventional automatic: Every 60,000 – 80,000 km
• CVT transmission: Every 40,000 – 60,000 km (CVT is more sensitive to pollution)
• DSG/DCT: Every 60,000 km or every 3 years
• AMT: Often follows the interval of manual transmissions

Note: Many manufacturers claim that the oil lasts "for life." In practice, this proves untrue. Regular oil changes significantly extend the life of the transmission and prevent costly repairs.

Two methods for changing oil:

1. Static refresh (drain): The lower crankcase is removed and the oil drains out. Disadvantage: only 30-50% of the oil is replaced. Advantage: cheaper and the filter can be replaced.
2. Flushing (dynamic): A flushing device flushes the transmission while the engine is running. Advantage: 95-100% of oil is changed. Disadvantage: more expensive, but much more effective.

At Faay Auto Groep, we often recommend a combination: first a static oil change with filter replacement, followed by a flush to remove all the old oil. This gives the best results.

Replace Filter

Many automatic transmissions have an internal filter that removes contaminants from the oil. This filter must be replaced regularly, usually at the same time as the oil change. A clogged filter reduces oil pressure and can lead to shifting problems.

Check Cooling

Automatic transmissions run hotter than manual transmissions. Most cars have a transmission cooler (often integrated into the radiator) to cool the oil. Check regularly for:

• Leaks in cooler lines
• Clogged cooler
• Faulty cooler fan

Overheating is a major cause of premature wear. Symptoms include a burning smell and dark brown or black transmission oil.

Repair and Overhaul of Automatic Transmissions

If your machine is broken, there are several options:

• Minor repair: Replacing sensors, solenoid valves, seals, or software updates. Cost: €200–€800.
• Major repair/overhaul: The gearbox is disassembled and internal components (clutches, plates, bearings) are replaced. Cost: €1,500 – €3,500.
• Exchange gearbox: Your defective gearbox will be exchanged for a reconditioned one. Cost: €1,200 – €4,000, depending on the type.
• New gearbox: A brand-new gearbox from the manufacturer. Cost: €3,000 – €8,000+, usually only worthwhile for very new cars.

At Faay Auto Groep, we always begin with a thorough diagnosis to determine the exact cause and extent of the damage. We then discuss the most cost-effective solution with you. Often, a problem can be solved with an oil change, software update, or sensor replacement, without having to disassemble the entire transmission.

Frequently Asked Questions about Automatic Transmissions

How long does an automatic transmission last?

With proper maintenance (regular oil changes), an automatic transmission can last 250,000 to 350,000 kilometers. Without maintenance, or with intensive use (heavy city driving, towing a trailer), its lifespan can be as short as 100,000 to 150,000 kilometers. CVT transmissions are generally more sensitive and have a shorter lifespan on average (150,000 to 250,000 km). DSG transmissions with proper maintenance can last a very long time, but the clutches may need replacing around 150,000 km with intensive use.

Should I have the transmission fluid changed if the manufacturer says it is for life?

Absolutely! The term "lifetime" often means "for the warranty period" or "for the expected lifespan as defined by the manufacturer" (often around 150,000 km or 10 years). In practice, transmission oil becomes contaminated and loses its properties after 60,000 to 80,000 kilometers. At Faay Auto Groep, we regularly see automatic transmissions break down around 120,000 to 150,000 km because the oil has never been changed, while comparable cars with regular maintenance easily reach 300,000+ km. An oil change costs €150-450, a new gearbox €3,000-8,000. The choice is quickly made.

Can I still drive with a gearbox warning light?

That depends on the problem. If the car goes into limp mode (won't shift), drive as little as possible and come in immediately for a diagnosis. If the car appears to shift normally but a warning light is on, you can often still drive, but schedule an appointment as soon as possible. Some problems worsen quickly if you continue driving. At Faay Auto Groep, we use diagnostic equipment to determine the severity of the problem and whether further driving is safe. In many cases, the warning light is caused by a minor malfunction (sensor, software) that can be easily and inexpensively resolved – but only if you act promptly.

What is the difference between DSG and a normal automatic?

A DSG (Direct Shift Gearbox) is essentially a robotic manual transmission with two clutches. One clutch controls the odd-numbered gears (1, 3, 5, 7), while the other controls the even-numbered gears (2, 4, 6) and reverse. While you're in gear 3, the transmission pre-selects gear 4, so shifting is lightning fast simply by switching clutches. Advantages: very fast shifting, more fuel-efficient than conventional automatics, sportier feel. Disadvantages: more complex, more expensive repairs, clutch wear (especially in heavy city driving), can be jerky at low RPM. A conventional automatic uses a torque converter and operates on oil pressure. This is smoother at low RPM but less efficient.

Why is my CVT so noisy?

CVT (continuously variable) transmissions sound different from conventional automatics because they don't have fixed gears. When accelerating, the engine speed often remains consistently high while the speed increases, which can feel like the clutch is slipping. This is normal behavior for a CVT and not a defect. However, a CVT can make a humming or buzzing noise, especially when accelerating. If this noise becomes much louder, it could indicate worn belts or cones. CVTs are very sensitive to oil contamination – have the CVT oil changed every 40,000-60,000 km to maximize its lifespan.

Can I tow a trailer with an automatic transmission?

Yes, that's possible, but not all automatic transmissions are suitable for heavy towing. Conventional automatic transmissions with torque converters are generally best suited for trailers. DSG transmissions can also tow, but the clutch wears out faster, especially with frequent hill starts. CVT transmissions are generally less suitable for heavy towing – always check the maximum towing capacity in your owner's manual. Tips for towing with an automatic: have the oil changed more frequently (every 40,000 km), use a lower gear when driving downhill, and don't let the automatic transmission slip for too long when starting on a hill. Consider adding an additional transmission cooler if you tow frequently.

My machine smells burnt, what now?

A burning smell from the automatic transmission is a serious warning sign. This indicates overheating of the transmission oil, often caused by slipping clutches or plates. Stop driving as soon as possible and have the car checked. Causes can include: very low oil level, severely contaminated oil, worn clutches, defective cooling, or excessive loading (e.g., towing a trailer while the transmission is not designed to handle it). Burned transmission oil completely loses its lubricating properties and can quickly lead to total gearbox failure. At Faay Auto Groep, we immediately check the oil level and quality and perform diagnostics to determine the cause. Often, damage can be limited if you intervene immediately.

Is a replacement gearbox a good solution?

A reconditioned replacement gearbox can be a very good and cost-effective solution, especially for older cars. You trade in your defective gearbox for a professionally reconditioned one fitted with new wear parts. Advantages: faster (often within 1-2 days), cheaper than a new gearbox, tested, and with a warranty (usually 12-24 months). Disadvantages: not all types are available as replacement gearboxes. At Faay Auto Groep, we collaborate with specialized reconditioning companies and can supply replacement gearboxes for most common automatic transmissions. We always recommend the most cost-effective solution for your situation.
