Recently got a 2014 Aston Martin Vantage V8. 56k miles Perfect condition. New clutch fitted just before we got it. I was driving around at normal speed, then at round about put it in 2nd gear and accelerated normally. When I went to shift into 3rd gear I pressed the clutch pedal (felt normal) and tried to shift gear. The gear lever stuck in 2nd gear and clutch not working. With the engine off, all gears engage OK, Seems like a clutch hydraulic problem, but there are no leaks or loss of hydraulic oil. Put car in 1st gear and started car and managed to get home, slowly. Any ideas?
