The transmission control unit manages how your automatic gearbox shifts. When it develops a fault or is replaced, it needs programming and calibration to work smoothly.
We program and calibrate transmission control modules to restore clean, reliable gear changes and dependable performance.
Harsh shifting, hesitation, or flaring can often be improved with the correct software and adaptations.
We update the gearbox software and carry out the necessary adaptations so your transmission shifts as it should.
We diagnose transmission control faults using live data and fault codes, then calibrate the unit to your vehicle.
This targeted approach resolves the underlying problem rather than masking the symptoms.
We support mechatronic units and carry out the relearn procedures many automatic gearboxes require after repair.
Every job is tested to confirm smooth, predictable shifting before you collect your vehicle.
We provide TCU programming for customers in Sandy and the surrounding areas, including Biggleswade, Bedford, St Neots, Shefford, Potton, and Hitchin.
