Code 26 is the Infamous Shift Delay fault code.

Most likely problem is a leaking cable control element at the tranny for delayed shift when engine is at warm up condition. This is an emmissions code and the concept is to hold the trans in second gear delay to help speed the cat up to temp.
Search archives for "Shift Delay'... I have a tutorial on the whole system in there somewhere.

Here are codes for you car and instruction for a retrieve tool for all the other Management Modules
