Specialists In All Makes Of Dual-Clutch Transmission

Established Since 1991 | Over 40 Years of Transmission Experience

Established in 1991, Beds Automatic Transmissions has over 40 years of specialist experience diagnosing and repairing automatic gearboxes, including advanced dual-clutch transmission systems.

What Is a Dual-Clutch Transmission?

A dual-clutch transmission, also known as a DCT, twin-clutch or double-clutch gearbox, is an automated manual transmission that uses two separate clutches. One controls the odd-numbered gears, while the other controls the even-numbered gears.

This allows the next gear to be prepared in advance, helping the gearbox deliver fast, smooth and efficient gear changes. Most DCT systems operate automatically but also allow manual gear selection using the gear lever or steering-wheel paddles.

Unlike a traditional automatic gearbox, a DCT usually does not use a torque converter. Instead, it uses either:

  • Wet multi-plate clutches, cooled and lubricated by transmission fluid
  • Dry clutch systems, fitted to certain makes and models

DCT gearboxes are known for their performance and efficiency, but their complex clutch, mechatronic and electronic systems require specialist diagnostic equipment and experienced technicians for accurate DCT gearbox repairs.

 

 

Mechatronic Units, Coding and Programming

Mechatronic Units Tested 

VW, AUDI, FORD, NISSAN, MERCEDES, VOLVO, MITSUBISHI ZF6/ZF8/ZF9.

In-House Mechatronic Coding and Programming

A mechatronic unit is the electronic and hydraulic control system used in many modern DSG and dual-clutch transmissions. It manages gear selection, clutch operation and hydraulic pressure to deliver smooth, accurate gear changes.

The unit combines a transmission ECU with a valve body containing solenoids, spool valves, check valves and springs. These precision components control the flow of transmission fluid throughout the gearbox. Designs vary between manufacturers, with systems such as the Porsche PDK operating differently from a conventional DSG gearbox.

Our Mechatronic Services

At Beds Automatic Transmissions, we provide in-house mechatronic diagnostics, coding and programming using specialist dealer-level equipment.

Our services include:

  • Testing mechatronic units
  • Coding and programming replacement units
  • Recalibrating DSG and DCT gearboxes
  • Diagnosing electronic transmission faults
  • Restoring gearbox operation following repairs
  • Checking clutch function and hydraulic pressure

Keeping this work in-house allows us to accurately diagnose faults, complete the required programming and ensure the gearbox shifts smoothly and performs correctly.

DSG & Dual-Clutch Transmission Servicing

Regular DSG and dual-clutch transmission servicing is essential for maintaining smooth gear changes, reliability and long-term gearbox performance. Servicing should always be completed at the manufacturer’s recommended intervals using the correct transmission fluid, filters and procedures.

A dual-clutch transmission effectively combines two manual gearboxes within one unit. During normal operation, small amounts of metallic wear debris, often called swarf, can build up inside the gearbox.

This debris may collect around important components, including:

  • Magnetic sensor pick-ups
  • Gear selector fork sensors
  • Speed sensor rings

If contamination is allowed to accumulate, it can affect sensor readings and contribute to poor gear changes, warning lights and electronic transmission faults.

Why Regular DSG Servicing Matters

Routine DSG and DCT servicing helps to:

  • Remove metallic debris and contamination
  • Maintain correct lubrication and hydraulic pressure
  • Protect sensors, clutches and electronic components
  • Reduce the risk of mechatronic and transmission control faults
  • Extend gearbox lifespan and reliability

At Beds Automatic Transmissions, we provide specialist DSG and dual-clutch gearbox servicing using the correct equipment and manufacturer-approved procedures. Regular maintenance is one of the most effective ways to prevent avoidable gearbox problems and costly repairs.

Repair
My Audi A3 hybrid had a major gearbox malfunction. After being let down by another company, Beds Automatic Transmissions stepped in. They picked up the car themselves and were only not able to repair my gearbox but they also managed to get the hybrid battery working again after over 2 months of being completely discharged.
I cannot recommend this company highly enough. They said they would attempt to repair the gearbox (which Audi wanted to replace in total) which they did with great efficiency. Nino, the owner, was also kind enough to write a repair report for me.

Gearbox Repair
Nino came highly recommended from a previous mechanic who promised he'd take good care of me - I'm clueless on cars. But that he did - not only is my car now driving smoothly as on Day 1 but the pricing (and warranty) was as best as could be imagined for a transmission issue as noisy as mine was. Not only was Nino and the staff simply lovely, you can tell the quality and pride someone takes in their work by the state of the place - organised, (dare I even say) very clean, professional. Thanks guys! I would definitely recommend your business to anyone.

Gearbox Repair
Took my BMW X5 to the team at Beds Automotive Transmissions because my automatic gearbox was slipping and making a slight noise on Saturday 28th March for a full gearbox service, on arrival k was greeted by one of the workshop lads who was polite and very professional, I was then pointed in the direction of the business owner Nino. I asked what was involved in the service he was more than happy to explain the full process and gave his time to run this by me even showing a 8 speed gearbox to similar to mine so I could see the internal workings of all. The service from start to finish was great the workshop lads were friendly. I left the garage after the service and it was like driving a new car, no slipping gears and no noises from the gearbox. I would highly recommend this company for any gearbox issues or concerns, if in doubt speak with Nino who will be more than happy to help or explain what is required. Top guys.

Gearbox Repair
Having an issue with an automatic gearbox is never fun or cheap - but appreciate the craft and complexity of doing the job properly. You can tell Nino knows his stuff, is a really pleasant and kind guy to converse with. After testing my car out for 2 weeks post repair, my Audi Q7 actually drives smoother than it did before. I really hope I never have to visit his shop again, but know a place i can return to if i am unlucky enough or even for a natter.
