How do you start it with it in gear? The way I know it is you could only start a car with automatic transmission being in Park or neutral, it will not turn over in Drive or reverse.

i don't know, bad mounts you feel the motor moving when shifting between gears not upon start up, I was thinking torque converter but that's so far fetched, he'd be noticing a lot more than just "lurching"

Anyways, lightning there's a way you can test to see if it is your motor mounts

You know how to burn out right? Well you'll need a second person or a camera to physically look at the engine as you put it in drive, press the brakes and give it gas while in drive, u don't need to mash the pedal to the floor, half throttle is more than enough and if they are bad then when you hit the gas the motor will rock back and forth. It will be obvious cause the motor will lunch forward 3-6 inches everytime you blip the throttle,,, this is y a second person or a camera is needed, you don't necessarily feel it but you can see it.

Let me know if that is what it is and not something else.

Might not be going in Park all the way, next time you go to shut it off, put in park for a few seconds longer then shut off. Might have to push lever in park with a tad of force to make sure it is going into park.

I never seen bad motor mounts launch motor 3-6" forward, I always seen them twist side to side, maybe a couple of inches with bad/broken motor mounts.

just like mine man same thing going on but i did over exaggerate how far mine moves forward its really like an inch but my engine mounts are good and i tired it again an give the shifter a bump to make sure it was in park an still did it seems like after it sits when engine is only cold it does it say if i drove it then tried to start it up while warm it doesn't do it. i am guessing its ok its goijng to have to stay like that i guess unless it gets worst but really i dont think it will hurt anything i hope not

What you have is a problem and not a problem.

Cold starts in cold weather mostly, people have been known to complain about the lurching forward, for alot of different years and models by Fords. Fords themselves do not have an answer to this.

So, is it a problem, in a sense yes, will it cause damage, there has not been one complaint of a trans failing because of this issue.

If it gets annoying, I would suggest stepping on brake pedal or apply the E-brake when starting, should stop the lurching feeling.
