when i bought the jeep it was low on transmission fluid, so i filled it up and then discovered it was leaking, at first i thought it was a bad fluid pan gasket so i bought the filter kit and replaced the filter and the gasket, after i drove it after that fix, the tranny stopped shifting normally and the rpm would get real high, it leaked the fluid again, so i dug around and found it to be Common transmission leak on many Chrysler products which is the electrical plug housing so i bought it and replaced it, the tranny wouldn't shift right still and now it goes into neutral after the 3rd or fourth gear. the "professionals" at aamco said it was a bad solenoid and charged me 300 dollars to replace it and then take back out saying it wasn't the problem. the check engine light came out a long time ago so i took it to auto zone and got these codes all of them pertaining to the tcm p0700 p0730 p1731 can you help me please? i hope its an easy fix~!

I strongly recommend you have the TCM ( transmission control module ) checked and tested-start here
