In my owners manual I found a "rolling start" section and I was excited thinking it might be for bumping the engine to start it. But the truth was they just allow pushing the starter button in neutral while rolling lol. Not sure I'd need to do a rolling start unless the starter is busted, but OK lol.
Had issues with key not making starter crank, so hardwired pushbutton to solenoid for my Saab 99LE.
One day the clutch fork broke.
I shifted up and down gears without clutch, came to a stop at light stalling the engine.
Light turns great, push the "crank" button, hit the gas, and it started and took off. Got home without a clutch.
Put same in Sable because my wife reported it wouldn't crank (maybe shift position switch issue? Or just shift position issue, or not standing on brake?) Haven't used it yet.
305 Superhawk, clutch cable broke in LA rush-hour traffic.
I shifted up and down without clutch, popped it into neutral at the lights.
To start, use toe shifter to put it into first (bit of chain slip), crack the throttle, drive on to next light.
The hand lever had a groove for cable, but a sharp angle in it. After buying a cable and completing trip, when I got home, found the problem, used a hacksaw blade to change angle into radius.
Other cars, I've also run gears up and down without clutch. Even cars with no synchro.
