[What Is Vehicle Gearbox Tuning? | What Is Vehicle Gearbox Tuning?]

Gearbox tuning customizes your transmission’s control unit (TCU) to optimize shift logic. We recalibrate shift points and analyze live data so gears engage smoothly—holding top gears on the motorway, delivering crisp up-shifts in sport mode, or gentle shifts for daily driving. The result is reduced wear, improved fuel efficiency, and a more responsive, enjoyable drive.

How It Works?

Step 1

Book Appointment

Select your appointment date, time, and location—either at our workshop or via our mobile tuning service—according to the service you choose. Once booked, you'll receive a confirmation email with appointment details, technician info, and preparation tips, plus a friendly reminder before your slot to ensure a seamless experience.

Step 2

On-Site Gearbox Tuning

Our technician arrives fully equipped, connects to your ECU, installs your custom Eco remap, fine-tunes key parameters, and verifies the results with live data logging—all in under an hour, right at your location.

Step 3

Data Report

Receive a detailed performance report, including before-and-after power and torque graphs, air-fuel ratio data, boost pressure logs, live sensor readings, and custom tuning insights—all tailored to your vehicle’s new map.

Gearbox Tuning Service

At Precision Remaps UK, we deliver comprehensive transmission recalibrations and coding solutions, including:

Towing & Load Calibration
Adjusts shift logic for late up-shifts under load, softens down-shifts to protect driveline components, and reinforces torque-converter lock-up for hauling reliability.
Custom Shift Calibration
Bespoke gearbox mapping tailored to your build—multi-mode presets (eco/sport/race), live-data logging, and iterative on-car validation to match your exact driving profile.
Transmission & Shift-Point Optimization
DSG/TCU recalibration with earlier up-shifts and extended holds to keep revs—and consumption—low.
Torque-Converter Lock-Up Tuning
Optimises lock-up engagement timing and slip control to improve highway fuel economy, reduce heat buildup, and enhance low-speed drivability.
Multi-Mode Shift Profiles
Programs distinct shift maps—economy, comfort, sport, or track—allowing on-the-fly selection of gear-change characteristics to suit any driving condition.
Adaptive Learning Reset
Clears stored transmission adaptations (shift pressures, clutch fills, throttle-to-shift mapping) to restore ideal factory behaviour or immediately apply new tunes.
