Truck lunges when engine is started

Ok, I have an 03 F250 auto with the V10. when I start the engine the truck makes a forward movment, then seems to settle back. The truck seems to run and shift fine otherwise. Any suggstions? Is this a hint of troubles to come?

I've never heard of it working quite like that. High line pressure in the transmission can cause a lurch or jump when shifting into drive. A lurch while starting sounds like the transmission is spinning forward when it should be locked in park. I would suggest trying to start the truck in neutral to see if it changes anything.

Yeah, I've noticed mine do that a time or two. Ditto on it happening on cold mornings.

well, it has been cold the last few weeks(15 low 30-40's for high). I will try the neutral start in the morning. Good to know i'm not the only one and it doesn't sound like its gonna fall out anytime soon. Thanks for info.
