It has OBD2. You can pull the trouble codes and see what is malfunctioning. Guessing is reckless.

Mechanic. I assume that by "slow" what you mean is slower than before.

Are you in fail safe mode? You only have reverse and 3rd gear when in fail safe. Starting out from a stop in 3rd gear will do that. Go to the dealer and have them use the factory scan tool to read any transmission codes you may have stored and read the transmission data to make sure all the sensors and solenoids are working with in spec.
