check engine light on code says not shifting into 2 or 4 could it be something besides the transmisson

Asked by for the 1995 Mercury Mystique
What codes are you getting? I'm not sure of a code saying not shifting into 2 or 4.

If you have transmission related codes, it must be transmission related, or at least transmission input related (range sensor, speed sensor).
