4 litre automatic 4 speed trans shifts into 2nd at around 5000 RPMs, then falls back into 2nd, highway shifts into 3rd Jeep falls on it's face,changed shift solenoid, tps. Shifts are better but still not right.goes into 2nd and 3rd, but is to soon. Still falls on it's face, bucks like not getting fuel, then it goes again. Sometimes Jeep will stall also sometimes driving around the city. I changed shift solenoid and the tps from Napa...shifts to soon and still stalls out at times, still falls on it's face. Help thank you....
