I've got a 5.4 triton with a little over 1000 miles on it. It's an automatic and it seems to hesitate a little when shifting. It's not smooth I don't think. It doesn't shift hard like snap my neck back but it does hesitate, This mainly happens when i'm on the gas about 1/2 throttle. When taking off and not hammerin down on the pedal it's not that bad, just at 1/2 throttle or harder.. any ideas guys..

 

It may be normal, I would take it by the dealer and have their tranny guy drive it since it is under warranty. If it was Bill Collins, then they will probably tell you it is normal, just like my crooked spring was and my idle vibration is.

I got it from star ford. I'm gonna drive the guy across teh streets tonight and see if his does it..

 

Get it looked at, becuase that is how mine started out and the tranny was toasted at 26,000 miles
