I have a 2012 mustang gt with 120,000 miles on it. Car might have had some exhaust mods done to it before i got it, but other then that car is stock. When I come out in first gear my car feels like it’s slipping. It feels like my car is stuttering. this Is my first manual car I’ve been driving it for like 4 months and it started doing it like last month. Would getting a new clutch fix this, am I driving it wrong, or am I overthinking this? I don’t know much about transmissions so I would like advise about what to do or fix.
