Automatic Gearbox

At Bruce Cousin Motors, we offer a complete automatic gearbox service, including power flush, diagnostic calibration, and repair work, all delivered by experienced and professional technicians who are experienced in modern automatic and semi-automatic transmissions.

What Is an Automatic Gearbox?

An automatic transmission uses hydraulic pressure, torque converters, and electronic control to shift gears without driver input. Over time, its fluid degrades, internal parts wear, and sensors/mechatronics need adjustment, which is why servicing is vital.

Common Symptoms You Shouldn’t Ignore

• Gear shifting feels sluggish, delayed, or jerky

• The transmission slips under load

• Strange noises (whine, humming, grinding)

• Fluid leakage or visible stains under your car

• Warning lights or transmission fault codes

If you spot any of these, bring your car in before problems worsen.

Our Full Automatic Gearbox Services

1. Comprehensive Diagnostic Inspection
   We use specialist scan tools to read fault codes, assess sensor data, and test hydraulic pressures.

2. Power Flush / Fluid Exchange
   Using dedicated flush machines, we remove old transmission fluid, clean internal passages, and refill with the correct ATF grade. This removes debris, sludge and helps extend transmission life.

3. Internal Parts Replacement & Repairs
   We replace worn clutches, seals, solenoids, valve bodies, or other parts as needed, using OEM or high-spec components.

4. Calibration / Adaptation / Reprogramming
   After repairs or fluid service, we reset and recalibrate the transmission control module (TCM) so the gearbox shifts smoothly and properly.

5. Final Testing & Road Verification
   Every car is road-tested to confirm shift quality, temperature behaviour, and system stability.
