hey I've got a 4l30e that is shifting hard but isn't slipping I have checked the tcm and cleaned it with no change..any help would be appreciated..fluid level is right

[@CurmudgeonTransmission]

Could be a lot of reasons for hard shifts. First thing you will need to determine is if high line pressure is being commanded or if it is doing it itself. First check would be line pressure. If it is high, you will need to determine why. If it is being commanded, what is causing the command. Check all things that tell the computer engine load. If it is not being commanded it may be a bad EPC, stuck PR valve, etc.

I appreciate the answer back..would be nice if I understand transmissions the way you...but it seems to have fixed itself somehow now I'm really at a lose can't fix it if it's working right🤷🏻‍♂️...but I will Chek those things if it does it again..and thanks again sir!!!!!
