When you have the pedal down all the way, you are still accelerating and it won't go into overdrive till you back off the pedal and go at a steady speed.

Well if you still have the gas pedal down it still will shift but it takes sweet time to shift and I went to a transmission place and there was no codes on the computer and he told me it was my tires but I don't know but I try to put my hypertech tuner back on but it said code 68 on the tuner and call hypertech but it throw a service engine light on and I took it back to the guy and he said the tuner can not communicate to truck computer. He said call hypertech and tell them what is the problem and if hypertech won't do anything go to the dealer to flash my truck computer
Thanks

A code 68 is an interruption during the programming session. Make sure you dont have any electrical acc operating at all. Make sure nothing is plugged in the cig lighter, if you have an aftermarket radio or amp or trailer brake you have to pull the fuse for them.
