My '06 will not shift into O/D after it reaches operating temperature. The past few mornings leaving work after about 15 miles I pull over, put the truck in Park, then shift back to drive and it shifts normally into O/D. Anyone have this problem or idea of what the problem may be???

 

Mine won't go into 5th until the trans fluid temp reaches a certain temp. Then sometimes you have to let off of the throttle slowly to get it to shift. 15 minutes is a little long though.

 

I travel 30 miles from work to the house and if I don't pull over it will not shift the entire trip during cold weather.

 

My 08 does the same thing. When the engine warms up it goes in o/d. I thought it was normal but then I've only had my truck for a few weeks.

 

my truck has started shifting weird the past two days also. Mine is also fine when its cold, but once it warms up it acts up.

 

mine does the same thing.
