Used automatic cars: test-drive checks and warning signs

“Automatic” covers torque-converter, dual-clutch, CVT and hybrid transmissions. Their maintenance and normal behaviour differ. Identify the exact gearbox and service schedule before assessing a used car.

Ask for service invoices, transmission repairs, warning messages and manufacturer maintenance requirements. A gearbox described as sealed for life still needs the manufacturer’s prescribed checks; do not authorise a fluid change without the correct specification and procedure. Compare mileage across invoices and MOT records.

During a safe test drive, observe the car from cold and after it warms. Note repeated delay engaging drive or reverse, slipping, harsh shifts, vibration, unusual noises or warning lights. One sensation does not diagnose a failure, but it is a reason for a specialist inspection. Do not perform risky manoeuvres or force the selector.

Ask an independent garage to scan relevant control modules and report findings. A general MOT does not assess every transmission fault. Request a written estimate if any issue is found, then decide whether to proceed. The Motor Ombudsman’s used-car advice explains consumer considerations.

Before paying, compare vehicle history and MOT checks and understand what to do if a fault appears after purchase. Confirm any warranty coverage and exclusions in writing.
