P0720 EXPLORER 2006

Transmission was jerky while driving forward, and reverse was almost non-existent. It seemed like the engine was back firing while in reverse. Changed out Output Shaft Speed Sensor, and Forward gears seem fine, but reverse is still very weak. Trans engages in R, but when you hit the gas, just engine revving and weak reverse action. Should I try to replace the Input Shaft Sensor as well? Had no problems until I changed out the EGR Valve, then P0190 Fuel Rail Pressure Sensor, P0720/0722 all showed up at the same time.

I am having the exaçt issue. I haven't done anything yet. Was going to clean my valve and change my sensor tomorrow. I'm not seeing any replies to your thread. I realize it was a couple years ago so I hope you see this. What did you do to fix this?
