when the truck is cold it shifts late,in 1st and 2nd,after it warms up it shifts right,or in the warm waether it shifts right all the time....any ideas?

 

For the most part it is normal for it to shift a little late when cold. But if it is excessive you can try a few things.
If it has low fuid it can make it shift differnt. You can try messing with the Tv cable. This helps with shifts.
