Specialists In All Makes Of Dual-Clutch Transmission
Established Since 1991 | Over 40 Years Transmission Experience
Established in 1991, we bring over 40 years of combined automatic transmission expertise, specialising in advanced gearbox technology and repairs.
What is a Dual-Clutch Transmission (DCT)?
A dual-clutch transmission (DCT) - also known as a twin-clutch or double-clutch gearbox - is an automated manual transmission that uses two separate clutches: one for odd gears and one for even gears.
It effectively operates as two manual gearboxes in one housing, working together for fast, smooth gear changes.
Although usually fully automatic, most DCT systems also allow manual gear selection via electrohydraulic control.
Unlike traditional automatics, a DCT does not use a torque converter. Instead, it typically uses either:
- Wet multi-plate clutches (oil-cooled)
- Dry clutch systems (in some models)
DCT gearboxes are widely used for their quick shifting, improved efficiency and performance, but require specialist knowledge for accurate diagnosis and repair.
MECHATRONIC UNITS & CODING
Mechatronic Units Tested
VW, AUDI, FORD, NISSAN, MERCEDES, VOLVO, MITSUBISHI ZF6/ZF8/ZF9.
In-House Mechatronic Coding & Programming
A mechatronic unit is the control system in modern DSG / dual-clutch transmissions, combining electronics, hydraulics and mechanical components to manage gear changes, clutch operation and pressure control.
It includes a valve body with solenoids and an ECU that controls transmission performance. Systems vary, with examples like the Porsche PDK, which differs from standard DSG layouts.
Inside the valve body, precision components such as spool valves, check valves and springs regulate hydraulic flow for smooth and accurate shifting.
Our Service
At Beds Automatic Transmissions, we offer in-house mechatronic coding, programming and diagnostics using specialist dealer-level equipment.
We can:
- Code and program mechatronic units
- Recalibrate DSG / DCT gearboxes
- Diagnose electronic transmission faults
- Restore correct gearbox operation after repair
Ensuring smooth shifting, correct clutch function and reliable performance.
DSG & Dual-Clutch Transmission Servicing
Regular servicing of DSG and dual-clutch (DCT) gearboxes is essential to maintain performance, reliability and prevent costly failures. All servicing should be carried out in line with manufacturer-recommended intervals.
A dual-clutch transmission effectively contains two manual gearboxes in one unit, which naturally produces metallic wear debris (swarf) during operation. This debris can collect around key components such as:
- Magnetic sensor pick-ups
- Gear selector fork sensors
- Speed sensor rings
If not removed through regular servicing, this build-up can interfere with sensor readings and lead to gearbox performance issues or electronic faults.
Why Regular Servicing Matters
Routine DSG servicing helps:
- Remove harmful debris and contamination
- Maintain correct gearbox lubrication
- Protect sensors and electronic components
- Reduce risk of mechatronic and TCU failure
- Extend gearbox lifespan and reliability
Proper maintenance is the most effective way to avoid expensive repairs and keep your automatic or DSG transmission operating smoothly.
