There could be a problem with the engine, and the computer switched into "limp home" mode.
Which normally puts the transmission in 2nd gear and keeps it there.
There could be a simple problem with the transmission like a speed sensor that has failed and the computer doesn't know what gear to put the transmission in.
There could be a major problem with the transmission.
The codes would give us more information to help prepare you for what the problems could be.
