Yes for the transmission because rebuilding is not something you can do at home.
There is one test to confirm if the problem is mechanical or otherwise. At transmission, disconnect the solenoid wire pack connector and g for a test drive. Start by manually shifting into each gear. The transmission is not going to shift automatically and if you have 1st, 2nd, 4th and reverse when each gear is shifted then problem is most likely to be the controls, meaning possible solenoid or valve body faults, a job that might not require a rebuild but repair to the valve body or electrical controls.
Check for trouble codes first.
