I was driving on a steep uphill offroad rocky track in a manual car with a rather weak engine, with my family in the back. I stopped at one point to check directions. I'm not used to manual cars and I didn't realise I was in second or third gear when I tried to start off again.
The track was very rocky, so I thought the wheels were trapped behind some rocks and I gave it plenty of revs and clutch to get going, near to the rev limiter. The car would move forward while I was slipping the clutch at almost max revs, then when I released the clutch the car stalled every time (because second / third gear lacked enough power to keep going uphill at low speed).
I did this 3 or so times, then after smelling strong burning, I re-checked my technique and realised my mistake.
Luckily I could complete my trip and drive home. Have I done any permanent damage?
