Very poor mid to high rpm performance.

I have a 96 cherokee inline 6. Ill start with the known issues. #1 transmission needs drained and filter needs replaced. recently on the highway its started shifting back n forth between drive and overdrive so im sure thats part of the problem. It also has a cracked header and possibly an exhaust leak. But now on the highway it will not go over 65mph. I held it to the floor for a few seconds and it wont budge over 3500rpms. It seems to still have decent pickup driving in town. Definetly not what it had before. I guess Im trying to figure out what the main part of the problem could be. Im on a bit of a budget and trying to fix one problem at a time. I just changed the oil and replaced the sparkplugs, wires and distributor cap and rotor. any help or advice would be great. thanks.
