Can you double check the engine codes becasue that number is not showing up.

Here is a guide:

Cannot find anything relating to a code 6100. From the description I would start with a scan with a dealer level tool to determine if this is engine or transmission related. It sounds like the transmission is going into limp mode but only testing it can confirm that.
