I start the truck up put it down in drive and it feels like its stuck in third gear you press the gas to the floor it does not go anywhere fast, it seems like it is slipping really badly drop it down to first and second it does fine, but in drive it feels like its stuck in third and does not shift into overdrive. I have already replaced the shift A and B solenoids along with the pressure control solenoid what could it be? Oh its a 4l60e.

Have a transmission professional scan for codes. It is in limp mode and will stay that way until fixed. Check transmission fluid if dark brown or black it is probably due for a rebuild.

I had a guy scan it it come up with a TCC circuit fault so this morning I took an ohm meter and checked every wire going from the PCM to the trans all had a constant 12 volt feed and I pulled the pan and did the same to all the solenoids. They all are okay and now all that is left is the pressure control switch you think that could be the problem and that was the only code it was throwing.
