The transmission codes and functions are often controlled by the ecm, engine control module computer. The ecm stores the fault codes from the engine and transmission. It is telling you that you have a transmission problem, the vehicle must have the ecm scanned by a certified technician, to properly diagnose the problem.
Bad speed sensor.
If it is not shifting and the check engine light is on, then the trans computer has detected a malfunction and set a code. You need to have the code checked to know what to diagnose.
A bad knock sensor would illuminate the check engine light and allow the engine to ping (spark knock). The engine doesn't shift, the transmission shifts.

Every sensor on the engine and transmission can cause the light to come on.
A low battery can cause the electrical system to flash check engine lights
Transmission jumping hard is the malfunction causing check engine light to come on,most likely its the tcc solonoid causing this or a possibility of causing this.
