Automatic transmission electronics
Mobile automatic gearbox TCM coding and calibration.
SG-Tronic Motorsport provides diagnostic-led TCM, TCU, EGS, DSG and automatic gearbox programming for supported vehicles. A gearbox warning, harsh shift, limp mode or replacement mechatronic can involve software, coding, parameterisation, learned values, wiring, voltage, sensors, hydraulics or mechanical wear, so we identify the cause before programming.
Gearbox calibration & adaptation
Manufacturer-appropriate basic settings, clutch or shift adaptation and post-repair verification where supported.
Mobile service Birmingham & UK
Mobile TCU programming across the West Midlands.
Selected vehicle-side diagnostics, coding and programming can be completed at a home, workshop, dealer or fleet location with safe access and stable power. Local coverage includes Stourbridge, Birmingham, Dudley, Halesowen, Wolverhampton, Walsall, West Bromwich, Solihull, Sutton Coldfield, Kidderminster, Bromsgrove and Coventry. Wider UK attendance is available by arrangement.
Automatic gearbox diagnostics
Full scan, TCM communication, live data, fault codes, power supply and network checks.
Replacement TCM programming
Part-number, hardware, software, VIN, coding and security compatibility assessment.
DSG mechatronic calibration
Supported DSG, DCT and dual-clutch basic settings and adaptation after appropriate repair.
Post-programming checks
Fault scan, data review, adaptation status and safe operational verification.
Bench programming & data transfer
Gearbox TCM and TCU module cloning.
Where a failed controller remains readable, selected flash, EEPROM, coding, immobiliser or configuration data can be transferred to an exact or approved compatible donor. Every clone is assessed by transmission type, controller manufacturer, hardware number, software version and vehicle security architecture.
Transmission controller families
Coverage may include Volkswagen Group DSG DQ200, DQ250, DQ381 and DQ500; ZF 6HP, 8HP and 9HP EGS; Mercedes-Benz VGS and 7G/9G-Tronic applications; Ford Powershift; BMW EGS; GM, Aisin, Jatco CVT, Getrag DCT, Temic, Continental, Bosch and selected commercial transmission controllers. See our real-workshop Mercedes automatic transmission TCM cloning case study.

Supported Audi, Bentley, BMW, MINI, Mercedes-Benz, Porsche, Jaguar, Land Rover, Range Rover, Volvo, Lexus, Maserati, Aston Martin, Lamborghini and selected high-performance vehicles require exact software, secure coding access and controlled voltage. We verify the controller and repair history before any write.
Automatic transmission modules by post worldwide
Approved TCM, TCU, EGS, DSG and mechatronic modules can be sent by tracked courier from England, Scotland, Wales, Northern Ireland, Republic of Ireland and Europe, with worldwide enquiries accepted by arrangement. Clear labels and diagnostic details are required before shipping.
UK & Ireland
Tracked postal assessment for compatible removable controllers.
Europe
Pre-approved shipping with customs and return delivery confirmed.
Worldwide
International bench programming enquiries assessed individually.
Before programming
Information required for accurate compatibility.
Vehicle identity
VIN, registration, make, model, year, engine and gearbox code.
Module labels
Clear photographs of original and donor TCM/TCU part numbers.
Diagnostic report
Full fault scan, symptoms, repair history and current communication state.
Programming history
Previous software, tuning, replacement parts and work already attempted.
Diagnosis before coding
Programming cannot repair worn clutches, damaged gears, contaminated oil, hydraulic pressure loss, valve-body wear or faulty wiring. Mechanical and electrical faults must be correctly diagnosed and repaired before calibration or adaptation.
When this service may help
Common symptoms and requirements
Gearbox warning or limp mode
A gearbox warning or limp mode can result from electrical, hydraulic, mechanical, adaptation or software faults. Diagnostic testing determines whether programming, coding or repair is appropriate.
Replacement TCU requires coding
For replacement tcu requires coding, our assessment checks the relevant vehicle data, control-module communication and supporting evidence before the correct next step is confirmed.
Failed or interrupted TCU flash
For failed or interrupted tcu flash, our assessment checks the relevant vehicle data, control-module communication and supporting evidence before the correct next step is confirmed.
Multi-brand capability
Cars, vans and specialist modules.
Automatic transmission and TCU programming coverage includes supported cars, vans, HGV and commercial trucks, motorcycles and scooters with electronic transmission control, marine and boat applications, personal watercraft, tractors and selected agricultural machinery. DSG, DQ200, DQ250, DQ381, DQ500, ZF, EGS, CVT, DCT, powershift and other controller families are assessed by exact part and software numbers.
Compatibility for Automatic Gearbox TCM, TCU, DSG & EGS Programming depends on model year, controller manufacturer, hardware, software and previous programming history. We confirm these details before booking to avoid unnecessary travel or module removal.
Frequently asked questions
What is the difference between TCM coding, programming and adaptation?
Coding configures the controller for the vehicle and fitted equipment; programming writes compatible control-unit software; parameterisation supplies vehicle-specific calibration data; adaptation or basic settings teaches supported clutch, pressure or shift values. The required procedure depends on the transmission and repair.
Can you clone a faulty gearbox TCM or TCU?
Selected readable controllers can be cloned to an exact or approved compatible donor by transferring supported software, coding, EEPROM and vehicle data. Compatibility depends on part numbers, hardware, software, transmission type and security architecture.
Do you offer mobile gearbox programming in Birmingham?
Selected diagnostics, coding and programming may be available across Birmingham, Stourbridge, Dudley, Halesowen, Wolverhampton, Walsall, Solihull and the wider West Midlands. Bench work or complex adaptation may require the workshop.
Can I send a transmission module by post?
Approved TCM, TCU, EGS, DSG or mechatronic modules can be accepted by tracked courier from the UK, Ireland and Europe, with worldwide enquiries by arrangement. Send vehicle details, diagnostic reports and clear module-label photographs before shipping.
Will TCM programming repair every gearbox fault?
No. Software cannot repair worn clutches, damaged gears, hydraulic pressure loss, valve-body wear, contaminated oil, sensor or wiring faults. Diagnosis determines whether programming, calibration, electronic repair or mechanical gearbox work is appropriate.
