Codes P1768 and 0700

P0700 - Transmission Control System Malfunction
P1768 - Automatic Transaxle

Code 700 is in the engine computer. It just means there is a fault code that needs to be read in the transmission computer. That is done because the defect can put the transmission into "limp" mode which keeps it in second gear. That increases fuel consumption, which increases emissions. Anything that could adversely affect emissions must turn on the check engine light, and that is the job of the engine computer.

That is about the sorriest definition I have ever seen for the second code, however, you will see the number is highlighted in blue. Click on that to go to a list of posts with similar problems. Most of these fault code numbers are generic and are not specific to just your model, so look at some of the other posts on that page.
