95 7.3 e4od hard shift rough idle

Hey guys I just bought a 95 7.3 4x4 with the e4od and I’ve ran into a little problem, when I start the truck in the morning it starts good runs good, but it has a very slight rough idle, when I start to drive it hard shifts if I’m easing into it or wot, the only time it doesn’t is when I’m 50% throttle, slowly as the truck warms up the rough idle gets worse and feels like it is bouncing me out of my seat, the hard shifts also get worse like it’s hesitating to shift and then bangs into the next gear, also if I’m driving down the highway at 100kmh and let off the throttle the tc will unlock(not sure if it’s supposed to do it), I checked the map wiring, all brake lights unhooked trailer brake controller Speedo and tach both work good, I haven’t had time to really dig into it and my mucar won’t scan it any place to start would be good thanks in advance

injectors need 45 PSi

Change the pump and clean the bowl out too or it can kill the pump quickly
