If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.
Is the engine light on? if so it sounds like it is going into "Limp Mode". This mode protects your transmission from damage should an error occur. Most of the time this error is a sensor that is going or has gone bad. Most of the time it is a speed sensor. Yours has two of these called an "Input" and an "Output" speed sensor. Since your transmission is shifted by a software package rather than a mechanical valve body like older transmissions, it needs to know what is going on by info received from all of the system sensors. When one sends an impossable value state, the software will put the transmission in 2nd gear and not let it shift. This is done to protect you transmission from catastophic failure by accendentally being in two different gear ratios at the same time.
You need to get the vehicle scanned at a trustworthy shop or dealer to determine what the code is. This will tell you what part is in question.
Also, just as a side note, check the transmission fluid level and make sure it is between add and full. Too much fluid can be just as bad as too little.
