About two months ago while driving the "trac off" light came on and the transmission shifted really hard after winding out the gears.
The next day the problem was gone. I changed the trans fluid and filter.

It started again today. The "transmission " light came on and shifts hard! The check engine light has always been on since I owned the car because of emissions issue. So I am not sure if there are additional codes to be read with this issue.


Any ideas? Maybe a sensor going bad?

It sounds like you have an input speed sensor that it not working right. We just had one in the shop with the same problem.
