I just bought a 2004 liberty don't know much about jeeps I was a ford man. It has 160 thousand miles and pulled the codes po700 po740 going to get the trans fluid changed and transfer case done think it was neglegeted, were would you suggest getting it done?

That's a torque converter out of range code. The P0700 simply means that you have a DTC in the TCM. You're probably looking at a failed torque converter clutch which is internal the the torque converter. If it shifts fine and doesn't default into limp-in then the transmission internals are working fine. A transmission service will not resolve your problem. I am a dodge jeep technician at at dealership and I suggest only OEM parts from a Chrysler dealer.
