Hey, I have 1998 Jeep Cherokee 4.0 with mutiple codes on it, It started about a month ago I replaced the torque converter for the code that came on. About 2 weeks later I noticed that the transmission was not shifing into 3rd nor overdrive, rather going into a neutral state, the codes that came up were P0700,P0758. So I picked up a solenoid kit and installed it to the specifcations, now I have a new code P0700, P0756. The transmission is still not shifting into 3rd or overdrive. Reading posts online I have exhauseted my thoughts, checked grounds, wiring, TCM, TPS, main computers,ABS. Can anyone point me in the right direction???
