4.0 Loses power at highway speeds
Hello, I'm new to forums, so here I go. I bought a 2002 WJ a few months back, it will accelerate to 60 with no problems if I floor it. The problem is if I take off normal, it seems to shift early into higher gears, leaving it no power and I can floor it and the rpms will stay the same or even lower. If Iím driving along at 55 and go to pass, I have to press the O/D off button on the gear shifter to get any acceleration. Just last week, it was beginning to start out in 2nd gear only, so I replaced the transmission pressure solenoid and sensor, which corrected that problem, but not the incredible loss of power. Please help.
Well, since no one decided to help me out with my problem, I went to two mechanics who both told me to go see a transmission specialist. So I called a few transmission specialists, who both thought my Catalytic converter was clogged. My question is from a dead stop it will go 0 to 70 with no hesitations, but the second i let off the throttle and hit it again, it loses all power. It won't down shift. So after a bit more research and testing, I determined that It is most likely the Throttle Position Sensor. I replaced it and the jeep runs like i guess would be new. This also corrected my high idling problem.
