My car's gearbox has been acting up for the past week. It's jerking when I shift from first to second and sometimes it feels like it's slipping. I'm in Al Nahda and I don't have a regular mechanic here so I've just been asking around. I came across gearboxrepairsharjah.ae while searching online but I don't know anyone who has actually used them so I'm a bit hesitant to book. Has anyone here gone through them for gearbox work? Did they diagnose the issue properly or just try to sell you a whole new transmission? I want someone who knows what they're doing and won't rip me off. Any real feedback would help because I need this sorted soon.
