Fernando Alonso doubts Aston Martin can safely contest this weekend’s Monaco Grand Prix unless its gearbox reliability improves. Unpredictable downshifts are the key risk on Monte Carlo’s streets amid gearbox issues.

He says the problem persists since Miami. Monaco downplays power but punishes drivetrain volatility. Random downshifts can trigger rear locking or aggressive engine push, pitching the car into barriers.

“Monaco is not the place to have a random downshift,” Alonso says. “Then you crash into the wall and the driver looks stupid.”

He adds some downshifts feel like unexpected throttle, making the car surge on entry. He targets Canada for an improvement, yet Monaco becomes the real test.

Lance Stroll broadens the diagnosis. Beyond downshifts, he highlights gear synchronisation across engine, transmission, and hydraulics. When sync drifts, shifts lag, costing time and driver confidence.

He says gears lose sync whenever speed drops below 40km/h. At Loews Hairpin, that means frequent re-syncs and a sizable lap-time penalty each lap.

Repeated re-syncs can lengthen braking and unsettle the car at apex and traction points. That threatens qualifying, Monaco’s decisive battleground, and reflects Aston Martin performance variability.

Alonso also addresses comfort, reverting his seating position after Canada discomfort. A more reclined layout, supported by technical leadership including Adrian Newey, created pressure points.

So the team returns to a 2025 baseline. He notes limited pre-season mileage restricted fit and systems tuning.

The longest Bahrain test run totals eight laps, leaving fundamentals unvalidated.

Monaco therefore becomes a reliability and execution exam. If gearbox behaviour repeats, the risk becomes unacceptable, undermining any strategy set out in Alonso’s prediction for the team’s near term.
