E4OD hard shifting

My dad has a 97 ford f250 powerstroke diesel, I believe this is the second transmission he's put in the truck (he didn't put it in recently) it has almost 300k miles and the transmission upshifts hard and downshift hard sometimes, He was towing a pretty heavy load with it when it started shifting hard

thanks in advance

Is there a question in here someplace?

Maybe I'll take a guess. You want to know if something is wrong? Read the codes. Everything starts with reading the codes.

I use a $25 ELM OBD-II connector and a free version of Forscan. I don't have a '97 diesel to make sure it works on that, but it works on all other Fords.

Several of these threads have been made numerous times of same transmission. Read through those first.
