2003 Saturn L300 Question: Transmission hard shift when check engine light comes on

I have a check engine light that won't go off and I have the battery disconnected hoping to reset the computer. I replaced the MAF sensor last night. However I also have had the transmission shift hard at times when the check engine came on. There was an post about this exact thing that wasn't answered and I wanted to know if you could help. Thanks -
Answer 1
I don't believe the check engine light has anything to do with trans shift, the light could be a number of things ie o2 sensor or catallitic converter or many other sensors. take to shop and have them run a code check first. -
