Fix Slow, Harsh or Confused Gear Changes — Without Replacing the Gearbox
If your car holds gears too long, shifts aggressively, hesitates when accelerating, or constantly changes gear on hills, the problem is usually not mechanical wear — it’s calibration.
Modern automatic and DSG gearboxes rely on software decisions. From the factory these are set conservatively for emissions, fuel testing cycles, and global driving conditions.
We recalibrate the gearbox control unit (TCU) so it selects the correct gear at the correct load — smoother in traffic, decisive under acceleration, and stable at motorway speeds.
The result is a car that feels mechanically healthier, without opening the gearbox.
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
Every gearbox has habits. Some hesitate, some rush, some never choose the right gear.
These adjustments correct the decision-making logic inside the transmission so the car behaves naturally again.
Towing & Load Calibration
Stops constant downshifting on hills or when carrying passengers.The gearbox holds the correct gear instead of hunting between ratios under load.
Custom Shift Calibration
Removes lazy kickdown and delayed response when you press the accelerator.The car moves when you ask — not a second later.
Transmission & Shift-Point Optimisation
Prevents high revving during gentle driving and unnecessary gear changes in traffic. Smoother progress with less throttle input.
Torque-Converter Lock-Up Tuning
Eliminates the “slipping” feeling at steady speeds.More direct drive and calmer motorway cruising.
Multi-Mode Shift Profiles
Comfort mode becomes smoother, Sport becomes decisive — instead of both feeling confused.
Adaptive Learning Reset
Clears bad habits the gearbox has learned over time so changes take effect immediately instead of weeks later.
Is My Gearbox Faulty — Or Just Behaving Badly?
Most gearboxes we see are mechanically healthy — they’re just choosing the wrong gear
We check live gearbox data before writing anything. If it’s mechanical, we stop.
Usually Calibration Behaviour
Jerky or clunky shifts at certain speeds. A delay when you press the accelerator. The gearbox hunts between gears on hills and the engine revs higher than expected while cruising. It behaves better once warm, no warning lights appear, and the car drives normally once moving. This usually indicates software behaviour rather than mechanical damage — fixable without opening the gearbox.
Usually Mechanical Wear
Slipping under heavy acceleration. A burning smell after driving. Grinding or whining noises from the transmission. Loss of drive in a gear, metal debris in the oil, or persistent fault codes present. This usually indicates a mechanical issue — we advise repair rather than tuning.
Mobile Service & Same-Day Availability
Within roughly 50 miles of Burton upon Trent, same-day appointments are often available where scheduling allows. This typically covers Derby, Nottingham, Leicester, Birmingham, Stafford, Lichfield, Tamworth and surrounding areas across Staffordshire, Derbyshire, Nottinghamshire, Leicestershire and the West Midlands. We also travel nationwide on pre-booked routes, so the vehicle usually stays where it is — no recovery or workshop waiting required.
What Drivers Notice Immediately
Pulling away feels natural instead of hesitant. The gearbox selects a gear and stays there rather than constantly changing its mind. Acceleration happens when the pedal is pressed, not a moment later. Cruising becomes quieter with lower revs and fewer unnecessary shifts. Traffic driving requires less throttle and feels smoother. The car behaves the way people expect an automatic to behave.
Our Gearbox Tuning Packages
Transmission Calibration – Stage 1 (Factory Behaviour Correction)
£220
Ideal for: Daily vehicles, stock engines, harsh shifting, gear hunting, delayed kickdown
What this actually does
Corrects OEM emissions-biased shift logic and adaptation behaviour without increasing drivetrain stress.
Includes
✔ ZF6HP / ZF8HP / DSG / DQ250 / DQ381 compatibility
✔ Reset & recalibration of clutch and pressure adaptations
✔ Removal of unnecessary short-shift economy behaviour
✔ Improved low-speed pull-away and parking smoothness
✔ Correct torque request communication with ECU
✔ Reduced gear hunting at steady throttle
✔ No additional wear introduced
Typical Result
Vehicle feels “normal” again — predictable, smooth and consistent.
Performance Transmission Calibration – Stage 2 (Torque Matched Mapping)
£320
Ideal for: Remapped engines, Stage 1/2 ECU tuned vehicles, e.g. M57/N57/TDI torque builds
What this actually does
Synchronises gearbox torque model with engine output so power is no longer reduced or misinterpreted.
Includes
✔ Raised torque monitoring & intervention thresholds
✔ Faster shift timing & pressure optimisation
✔ Manual mode gear hold (no forced upshift)
✔ Correct kickdown behaviour under load
✔ Launch & downshift response improvement
✔ Designed for ZF8HP, 6HP and wet-clutch DSG platforms
✔ Prevents clutch slip & torque reduction after engine remap
Typical Result
Car finally uses the power it already had — no flat spots, no throttle delay.
Heavy-Duty / Custom Configuration Calibration
£349 - £599
Ideal for: Recovery trucks, vans, towing vehicles, hybrid turbo builds, M57 swaps, gearbox conversions, non-standard configs.
What this actually does
Custom builds the gearbox strategy around how the vehicle is actually used, not how the manufacturer assumed.
Includes
✔ Torque-converter lockup strategy for towing & weight
✔ Gear holding under load (no constant downshift hunting)
✔ Cooling & slip reduction under heavy throttle
✔ Custom RPM shift bands for commercial use
✔ Compatibility with engine swaps (M57 conversions etc.) Including Immobiliser Off Solutions
✔ Adjusted protection logic for oversized tyres / axle ratios
✔ Post-installation revisions included
Typical Result
Vehicle stops fighting itself — pulls smoothly, holds gears, and survives daily work use.
