New to this site and I have a question about my F150 4x4 It is a 2000 bone stock I have had it for about a year and half with 15000 miles. 4.6L motor.

Question: It seems to me that when the tranny is warm that it becomes very sluggish. It seems that it likes to stay in the highest gear possible and will not shift on its own till the RPM's get real low. When the truck is cold it is very snappy but as soon it as it warms up it just sucks plain and simple has no power. Almost feels like the tranny is slipping? I have taken it back to the dealer and they say everything is fine no problems and that it is normal. Well for some reason I do not think it is. Any commenst would be a great help.

Thanks
