Get the codes read using Techstream, everything else is just guessing..

Yes, you need to check for any error codes first. The fact that it is going into 4th rules out the temperature sensor and control (which limits 4th  gear or higher when cold) so it is likely to be a shift solenoid and if one has open or short resistance you will get an error code. If no codes then it could be a sticking solenoid or poor quality ATF or low fluid level.
