Professional transmission control unit remapping designed to deliver smoother gear shifts, improved response, and a more connected driving experience - tailored specifically to your vehicle.
Your vehicle's Transmission Control Unit (TCU) governs every gear change your automatic or dual-clutch gearbox makes - shift points, clutch pressure, torque delivery, and response speed. Like the ECU, it leaves the factory with a conservative, compromise-driven map that prioritises mass-market comfort over driving quality.
The result is sluggish shifts, unnecessary gear hunting, and a disconnect between what you ask of your vehicle and what it delivers. Broadway Remapping's TCU remapping service rewrites that map - optimising every aspect of your transmission's behaviour to suit the way you actually drive.


A factory TCU map is built to feel inoffensive to the widest possible range of drivers. That often means soft, drawn-out gear changes that feel vague and disconnected. Our TCU remap recalibrates shift timing, clutch engagement, and torque transfer to produce gear changes that are cleaner, faster, and far more satisfying - whether you're pulling away in traffic or accelerating at speed.
Smoother, more refined automatic gear changes
Reduced gear hunting on motorways and dual carriageways
Improved shift speed on dual-clutch and automatic gearboxes
Better torque delivery across all gear changes
Automatic and dual-clutch gearbox vehicles
Drivers frustrated by hesitant or sluggish gear changes
Vehicles that feel disconnected or unresponsive in auto mode
TCU remapping goes beyond just smoothing out gear changes. By optimising shift points, kickdown response, and torque limitations within the transmission, we transform how your vehicle performs across all driving conditions. Whether you're towing, carrying loads, or simply want a more engaging daily drive, a remapped TCU makes your vehicle feel sharper, more capable, and more intuitive to drive.
Optimised shift points for real-world driving conditions
Faster kickdown response when overtaking
Improved performance when towing or carrying heavy loads
More engaging and responsive driving experience overall
Drivers who want better performance without engine modifications
Vehicles used for towing, hauling, or heavy-duty work
Anyone looking to complement an existing ECU remap


For the best possible results, TCU remapping works hand in hand with an ECU remap. When both the engine and transmission are optimised together, every aspect of your vehicle's performance improves in harmony - the engine produces power more efficiently, and the gearbox delivers it more effectively. Broadway Remapping offers combined ECU and TCU remapping packages, ensuring your entire drivetrain is working at its best.
