Diagnosis
Common Symptoms
Harsh or Delayed Shifting
If your car hesitates significantly when shifting into drive or reverse, or if you feel a noticeable jolt, bang, or clunk when the gears change while driving, this indicates internal pressure issues or worn components. Do not ignore these sudden changes in shift quality, as they can quickly lead to catastrophic failure.
Transmission Slipping
This is a highly dangerous sign where the engine revs increase, but the vehicle doesn't accelerate proportionally. You might feel a momentary loss of power, especially under load or when climbing a hill. Slipping means the internal clutches are failing to fully engage, causing friction, overheating, and rapid damage inside the gearbox.
Fluid Leaks or Low Levels
A pool of red, brown, or dark fluid under your vehicle is a critical warning sign. Automatic transmission fluid (ATF) cools and lubricates your gearbox; a leak means essential components are running dry and overheating. We recommend inspecting the fluid level immediately and booking a professional check-up to identify the source of the leak and prevent irreversible damage.
Automatic Gearbox Repair
Expert Solutions for Faulty Automatic Transmissions
If your automatic vehicle is exhibiting unusual behaviour—such as delayed shifting, slipping between gears, or strange noises—it’s crucial to seek professional help immediately. Our Irish-based workshop specializes in fast, accurate diagnostic testing using state-of-the-art equipment to pinpoint the exact cause of the fault. We address a wide range of common automatic gearbox issues, including solenoid failures, electrical faults, and pressure problems. By focusing on repair rather than immediate replacement, we aim to provide the most reliable and cost-effective solution to get your vehicle back on the road safely and efficiently.
Automatic Gearbox Servicing
Protecting Your Transmission with Preventative Maintenance
Regular servicing is the single most effective way to extend the life of your automatic transmission and prevent costly future failures. Despite what some manufacturers claim about "lifetime fluid," the reality of driving conditions across Ireland means that transmission fluid degrades over time due to heat and contamination. Our comprehensive service involves a complete drain of the old fluid, a replacement of the filter, and a refill with high-quality, manufacturer-specific automatic transmission fluid (ATF). This routine maintenance ensures optimal lubrication, cooling, and performance, keeping your gearbox shifting smoothly and reliably.
Automatic Gearbox Reconditioning
A Cost-Effective Alternative to New Gearbox Replacement
Automatic gearbox reconditioning is our premium solution for heavily worn or severely damaged transmissions. Unlike a basic repair, reconditioning involves completely removing the gearbox, stripping it down to its component parts, meticulously cleaning the casing, and then replacing all worn clutches, seals, gaskets, and bands with brand new, OE-quality parts. This process restores the unit to its original factory standards, providing a level of reliability and longevity that often matches or exceeds a brand-new unit, but at a significantly lower cost. We provide a full warranty on all reconditioned gearboxes for total peace of mind.

"Nissan CVT import failed, 7th Gear recommended. Difficult to make contact but eventually succeeded. Had the car for 15 days, said it would take 2 weeks. Car driving perfectly, 1 year guarantee and price less than original quotation. Overall, little less than full marks for initial contact, full marks for communication after that and very definitely full marks for work done and for pricing. Very efficient and professional. Thanks"

"Unusually for Ireland I could book my car in for a Saturday appointment which meant it didn’t interfere with weekday needs. My auto gearbox was in need of a full service. After getting quotes for up to €320 from others, I had the service done here in one hour and paid €220. Friendly and efficient service from a very busy specialist transmission shop. Thanks 7th Gear !"

"VW DSG Gearbox Fixed – Brilliant Service! I recently had issues with my 7-speed DSG automatic gearbox, showing repeated transmission failure errors—really worrying stuff. After doing some research, I brought my car to 7th Gear Gearbox Repairs, and I'm so glad I did. From the start, their team was professional and reassuring. They carried out a free gearbox performance check, including a full diagnostic and road test. They explained everything clearly and gave me a free quote before starting any work, which I appreciated. ON A SATURDAY! The repair was done quickly and thoroughly in their dedicated machine shop. They rebuilt the gearbox and resolved the issue completely—no more error messages, and the car now drives smoothly and confidently. Best of all, their work came with a 12-month unlimited mileage guarantee, which gave me total peace of mind. Everyone I dealt with was friendly, knowledgeable, and genuinely cared about getting it right. I highly recommend 7th Gear if you're having any gearbox problems—especially with DSG transmissions. Truly expert service!"

Frequently asked questions
Still have questions about your Automatic gearbox repair or need specific advice on an Clutch & Flywheel replacement? Don't Don't hesitate to contact our expert transmission specialists directly. We are ready to provide the precise answers and tailored solutions your vehicle requires.
- What is the difference between Automatic Gearbox Service, Repair, and Reconditioning?
- Service is preventative maintenance, typically involving a fluid and filter change to ensure smooth operation and extend component life. Repair addresses a specific fault, such as a leak or sensor issue, often without removing the entire gearbox. Reconditioning is a comprehensive overhaul where the gearbox is fully stripped, cleaned, and all worn internal parts are replaced with new components, restoring the unit to its original factory specification.
- How often should my Automatic Gearbox be serviced?
- We recommend a full automatic gearbox service every 40,000 to 60,000 miles (65,000 to 95,000 km), despite manufacturer claims of "lifetime fluid." Given the strain from frequent stop-start Irish driving conditions, regular servicing is crucial. This proactive maintenance schedule prevents fluid degradation, ensuring reliability and helping you avoid more expensive repairs in the future.
- What are the common warning signs that my automatic gearbox needs a repair?
- You should watch for several key warning signs. These include noticeable delays or hard clunks when the car shifts gear, the feeling of the engine revving without corresponding acceleration (slipping), or any unusual whining or humming noises coming from the transmission area. Additionally, any red or brown fluid leaking beneath the vehicle is a clear indicator of a potential problem that requires immediate diagnostic attention.
- Is it more cost-effective to repair or recondition my automatic gearbox?
- Choosing between repair and reconditioning depends on the extent of the damage. A simple repair is the most cost-effective option for minor faults like leaks or external sensor issues. However, for significant internal damage or high-mileage units, reconditioning is often the better long-term investment. Reconditioning offers a fully restored, guaranteed unit that provides greater longevity and superior performance compared to simply fixing a single faulty component.
