I don’t think your friend understands how an impact gun works unfortunately S:(

You will be fine removing the bolt with an impact gun. Just make sure you torque the bolt down to specifications as suggested already.

Quoted From Beefy:

The engine is free to turn when a car is in park. The torque converter is a fluid coupler. It will not engage the transmission with only a few hundred rpms. Otherwise, how would you start the engine? You don’t put it in neutral. That’s why you have to push in the clutch or put the car in neutral on older model standard trans cars/trucks that don’t have a NSS.

And that is why this forum is AWESOME! Thanks Beefy, very very good point…there you go again with stating the obvious for me 🙂

I have actually seen this in service repair manuals on some cars. I have used impacts and never had a problem either.
Chances are you will do more damage to other things tugging on a cheater bar and wedging some thing in flywheel ring to break bolt loose.
I have seen Kilmer crank the engine with a breaker bar in place to break it loose. Now that I would recommend against that!
