Question about 2004 Jeep Grand Cherokee
Transmission are slipping
The code you have means that an automatic test which the transmission controller performs each time failed twice. It is a test of a pressure switch inside the TRS/solenoid block. This could have several reasons, but the first check is to see the fluid level and smell the fluid. If the level is low, fill it to the right level. If the fluid looks black and/or smells burnt, then you really have a slipping clutch inside. But normally when a clutch starts slipping you will get more fault codes. The transmission controller compares the input with output speed to see if it slips and if it does, it will give you a code for it. It can be that the failing test causes the transmission to go into limp mode, which is third gear. You get then the feeling that it is sluggish and slipping. Most of the time the pressure switch itself is the problem. You then need to replace the whole TRS/solenoid block.

I just had the same with mine, pull the rubber boot back on the drivers side front door and look for a severed wire, mine was black...simply spliced the wires back together and problem solved!

12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle. Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.

There's a small space behind inside fender. You can get your hand in there to grab and twist the back of the bulb to release it. You need a flashlight.

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

You may have a faulty sensor, most cases a wheel speed sensor, the light is on warning you that you do not have abs basically your car will stop like an old 70's model car before abs. abs atands for anti lock brakes, it keeps your brakes from locking up under extreme braking.
