Have had my Fiat 500 for 18 months now and since I have had it I have had problems with my gears sticking!! Mainly in first and second but it happens in other gears also. Have taken it to numerous garages and spent lots of money but problem hasn’t been solved. Some days it drives fine but more often than not I have the issues with the gears sticking. I have noticed it is worse when it’s hot and sunny or like today very cold.I paid to have it examined by ACE and received the report back that there was an issue with the gears but no clarification on what it was or how to resolve. Can anybody give me some help or advice as garages and Ace Inspection hasn’t been able to. Thanks
