TCU Remapping
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 gearbox is holding your vehicle back We change that.
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.
Smoother Gear Shifts Refined Transmission Behaviour
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.

Improved Driving Performance A Gearbox That Works With You
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.
