..and you claim that your method is better because mine will blow the engine and yours will blow only a muffler? We are not talking about a 40 year old car with a manual transmission.
Sorry everyone else, but The9 doesn't have a CLUE what happens with a modern car if you shut the engine off in gear. Try, destroying your $5000 transmission, not your muffler.
What do you think happens when a car is rolling with no power and the transmission in gear, anyway? They don't even want modern cars towed on the ground because of potential damage.
If you shift to neutral and immediately turn the engine off, odds are there will be no damage beyond what the initial revs may have done. Forcing the engine to fight the gearing is worse than overrevving it for a second. For the average driver, the procedure I described is the easiest to learn, and has the largest margin for error.
The9, your mechanic experience hasn't taught you a dam thing. You have to twist my posts to accuse me of BS. Then you're so busy massaging your own baseless ego, that you can't even understand a simple analogy. Construction, or automotive, or whatever, there are thousands of guys who have worked in an industry for decades and still can't do the job right. You are the perfect example of that point. Thank you for helping me make it.
To everyone else, there is absolutely no reason to leave your transmission in gear when you shut off a runaway engine, unless you want to replace it.
